130k+ vending machines from a business you wouldn't expect

Today, I'm digging into Fastenal Company (FAST).

They sell nuts, bolts, screws, and then a long tail of safety gear, cutting tools, janitorial supplies, and general maintenance products. Fasteners are obviously where the name comes from and still about a third of sales.

This is a company that pretty much sells commodities and it still earns roughly 20% operating margin. That is not normal for distribution and the reason why is probably the most interesting part of the company.

A few things that stood out to me:

• They moved the store inside the customer. Fastenal has more than 136,000 vending machines and sensor-equipped bins installed on customer factory floors, plus a growing base of Onsite locations that are literally branches inside a customer's building. I'm sure this is done in other businesses, but honestly I think this is the first I've heard of this type of on-site installation. I love it, and it obviously builds sticky relationships.

• About 61% of 2025 sales now flow through their digital channels and managed-inventory technology, and contract customers are nearly 74% of revenue.

• The stock has returned roughly 420% over the past decade on a dividend-adjusted basis.

• Net debt is essentially zero. This is especially impressive given that their business has morphed into what is inventory/parts-as-a-service. And a growing distribution business typically funds working capital increases with debt.

But it's not all clean and perfect:

• Demand is cyclical and tied to manufacturing activity and non-residential construction.

• Gross margin has drifted down slightly as big national accounts and Onsite customers negotiate better pricing. Growth and margin play a game of tug of war for them!

The key takeaway for me: In a commodity business, your customer can buy the same thing from multiple companies, so the most natural place to compete is on price. Fastenal's answer was to stop being a vendor the customer visits and embed themself with the customer.

In further reflection on this, this isn't a completely novel model. Here are a few examples where this exists today.

• Office coffee/pantry supplies

• Managed printers/copy machines

• Office micro-grocery stores

• Ecolab cleaners

• Branded and managed soda fountains

• Quite a few more

At the end of the day, if you have a commodity product, you need to come up with a differentiated way to add a service to your offering. That's exactly what Fastenal has done.

I really like this model. I'm going to keep my eye open for any unique opportunities to place consumable-type products close to customers that aren't being done today. And you should do the same.

With that, I'll see you on Tuesday!

TL;DR

• Fastenal is the largest fastener distributor in North America, and a broad industrial and construction supplies business with about $8.4 billion in TTM revenue.

• It makes money selling fasteners (around a third of sales) plus safety, tools, and MRO products, increasingly delivered through on-site vending machines, bins, and embedded Onsite branches.

• Recent growth has re-accelerated, with full-year 2025 sales up about 9% and the most recent quarter up over 12%, driven by managed-inventory adoption.

• The financial profile is rare for distribution: roughly 45% gross margins, around 20% operating margins, near-zero net debt, and about 33% return on equity.

• On the stock, Fastenal has compounded roughly 420% over ten years, but over the past year its return actually trailed both Grainger and MSC Industrial.

• Operator takeaway: in a commodity category, you can win by owning the customer's point of consumption.

The 30,000-Foot View

Fastenal buys industrial and construction supplies in bulk and gets them to the people who need them, fast and reliably. The classic version of this was a local branch full of bins, staffed by people who know the contractors and plant managers in town. That branch model still exists, with roughly 1,600 locations, but it is no longer the growth engine.

The growth engine is what they call FMI, or Fastenal Managed Inventory. Think industrial vending machines (FASTVend), smart bins with weight and infrared sensors (FASTBin), and stocking programs that sit physically inside the customer's facility. When a worker pulls a part, the device records it, and Fastenal sees consumption in real time and restocks before the customer runs out. Layer on Onsite locations, which are dedicated Fastenal branches operating inside a large customer's plant, and you get a business that is woven into the customer's daily operations rather than competing for their next order.

That embedded model is why the numbers look the way they do. Sales through FMI technology reached $3.71 billion in 2025, about 44.7% of total sales, with FASTBin and FASTVend alone driving $2.68 billion, or 32.2% of the company. Their broader Digital Footprint, which adds eCommerce and electronic data integration, hit 61.4% of sales. Contract customers, the large signed accounts, were nearly 74% of revenue. The more of the customer's plant Fastenal stocks, the harder it is to ever pull them out.

Company History

• 1967: Bob Kierlin founds Fastenal in Winona, Minnesota, originally hoping to sell fasteners out of vending machines, an idea decades ahead of the technology.

• 1987: Fastenal goes public on the Nasdaq.

• 1990s to 2000s: Aggressive branch expansion across the U.S., growing into the largest fastener distributor in North America while broadening into non-fastener product lines.

• 2008 to 2011: Pushes hard into industrial vending, planting the seed for the FMI model that now defines the company.

• 2015 to 2017: Pivots from opening branches to signing Onsite locations and deploying vending devices, a strategic shift toward embedding inside large customers.

• 2016: Daniel Florness becomes CEO after years as CFO.

• 2020 to 2022: Demand surges through the industrial recovery, and FMI technology becomes the clear growth driver.

• 2025: FMI device base passes 136,000, Digital Footprint clears 61% of sales, and the company announces a CEO transition, with Jeff Watts set to succeed Florness in July 2026 as part of an orderly succession that began in 2024.

• 2026: Raises the quarterly dividend about 9% to $0.24, extending a 33-year payout streak, and sets a higher device-signing goal of 28,000 to 30,000 units.

Show Me the Money

Standout financial features:

• Steady revenue growth. From $7.0 billion in 2022 to $8.2 billion in 2025, and growth re-accelerated to over 12% in the most recent quarter as managed-inventory adoption picked up.

• Operating margins around 20% are exceptional for distribution. For context, a well-run IT reseller like CDW earns closer to 8%.

• Net debt fell from $572 million in 2022 to about $165 million in 2025, and most of what remains is finance leases on vehicles and buildings rather than borrowed money.

1-year total return vs. peers:

Peer notes for the comparison: W.W. Grainger (GWW) is the largest North American MRO distributor and the closest scaled competitor, and MSC Industrial (MSM) is a metalworking and MRO distributor that competes directly for the same plant-floor spend. Both are public with long trading histories, which makes them clean comparisons.

The N.O.O.B. Nine: Competitive Powers

The Nerd Out on Business Nine is made up of Hamliton Helmer's famous "7 Powers" of competitive advantage (Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource, and Process Power) combined with two of my own (Data Flywheel and Distribution Advantage).

Average Score: 3.3/5 - a scale-and-distribution moat where the real edge is embedded, on-site delivery that turns a commodity business into sticky, recurring volume.

Memorable Marketing

Fastenal does almost no traditional advertising. Its marketing budget is essentially its distribution model: the most persuasive sales pitch is a Fastenal vending machine already sitting on your factory floor. The product-delivery mechanism is the brand.

Notable tactics:

• Industrial vending as land-grab (ongoing): Placing a branded FASTVend or FASTBin device inside a customer's building claims permanent shelf space and quietly locks out competitors.

• Onsite locations (ongoing): Moving a staffed branch into a large customer's facility makes Fastenal part of the customer's operation rather than a supplier they call.

• Milestone PR: The company turns operational achievements, like installing its 100,000th vending device, into press and credibility with prospects.

• The Blue Print content hub: A practical content site aimed at supply-chain and operations leaders, building trust through education rather than hype.

Tactical takeaways:

1. Make your delivery method the marketing channel, so growth and fulfillment reinforce each other.

2. Win physical or digital real estate inside the customer, because presence beats persuasion.

3. Use consumption data from that presence to surface the next product to stock.

4. Publicize operational milestones as proof points, not vanity metrics.

AI Uses & Opportunities

Current exposure:

• Fastenal has been quiet about AI specifically, but it sits on an unusually rich, real-time dataset: granular consumption from 136,000-plus connected devices across thousands of customer sites.

• That data already powers automated replenishment and demand signals, which is the unglamorous, working version of machine learning in a distribution business.

Future opportunities:

• Predictive replenishment and stockout prevention tuned per device, per part, per facility.

• Dynamic pricing and quoting informed by account-level consumption patterns.

• Computer vision in bins and cameras to track inventory and usage without manual scanning.

• Sales-rep copilots that recommend which product lines to add at a given Onsite based on what similar plants consume.

• Demand forecasting that ties device-level signals to broader manufacturing activity for smarter purchasing.

Bumps in the Road

• Cyclicality. Revenue tracks manufacturing output and non-residential construction, so an industrial slowdown directly reduces how many parts customers consume.

• Tariff and supply-chain exposure. Fastenal sources a large share of fasteners from overseas, so tariffs and freight swings hit cost and pricing.

• Slow margin dilution. The biggest, stickiest customers get the best pricing, so the same national accounts that drive growth also pressure gross margin over time.

• Demand sensitivity in signings. Cutting the 2025 device-signing goal mid-year showed that even the embedded model is not immune to a soft industrial backdrop.

• Leadership transition. Daniel Florness steps down in July 2026 with Jeff Watts taking over, and while the succession looks orderly, any CEO change at a finely tuned operator carries some risk.

• Premium valuation. The market prices Fastenal like a proven compounder, which leaves little room for execution stumbles.

Your Swipe File

• Put your product-delivery mechanism inside the customer's building.

• A device that meters usage and restocks itself can be quite valuable to customers. And give you some extra margin while greatly increasing stickiness

• Push P&L responsibility down to the store or site level so every location behaves like an owner.

• Be willing to trade a little gross margin for recurring volume, because lifetime value is what matters most.
