This analysis covers Fastenal, which isn't just a bolt seller but acts as an outsourced procurement department for big clients like Amazon warehouses. Fund manager Delian Entchev is bullish, citing its frugal culture, high margins, and market share gains. Three key holdings: Fastenal (high profit margins, nearly debt-free), Amazon (a top customer), and Grainger (a competitor with lower margins).
Fastenal has evolved from a small fastener retailer in Minnesota into a key partner in the industrial supply chain, with a market capitalization of nearly $50 billion and annual sales of approximately $8 billion.

Delian Entchev, portfolio manager at Aoris Investment Management, breaks down Fastenal — from a small fastener retailer in Minnesota to a critical industrial supply chain partner with a market capitalization of nearly $50 billion and annual sales of approximately $8 billion. Delian Entchev argues that Fastenal's core is not that of a "distributor," but rather a "customer's procurement outsourcer" — through on-site locations, industrial vending machines, and smart inventory management systems, it embeds itself within customer operations, allowing customers to worry about none of their supply chain matters.
Delian Entchev emphasizes that simply describing Fastenal as an "industrial supplies distributor" severely undervalues its significance. "It's not just moving boxes from A to B; it's more like the customer's procurement outsourcing department." He uses Amazon as an example: Amazon is one of Fastenal's largest global customers. Amazon's warehouses need cleaning supplies, conveyor belt maintenance parts, and employee safety gear (gloves, goggles, earplugs)—Fastenal ensures these items are always in stock, allowing Amazon to focus on what it does best.
Core value proposition: reducing the customer's total cost of ownership. After analyzing its customer accounts, Fastenal found that, on average:
"Fastenal doesn't offer everything to everyone. Some customers just want the lowest price; Fastenal doesn't serve them." Approximately 120 new accounts are signed each year, of which 72% no longer do business with Fastenal after five years, and only 2% eventually grow into meaningful long-term accounts. If a customer does not spend enough, Fastenal will remove its vending machines or on-site personnel.
Delian Entchev points out that Fastenal’s culture of frugality is the core legacy left by founder Bob Kierlin, but “frugality should not be confused with stinginess.” Even today, the CEO and CFO still share a hotel room when traveling on business. This is not about saving money, but about sending a signal to “act like an owner.” Most Fastenal employees share offices within their branches.
The mechanism through which frugality creates a competitive advantage:
“Ordinary people, when given the opportunity, can do extraordinary things.” This is what Kierlin wrote in The Power of Fastenal People. 95% of branch managers and above (including the executive team) are promoted from within. New employees experience a higher turnover rate in their first 1–3 years (this model is not for everyone), but once they stay, they typically remain for 30–40 years.
Delian Entchev emphasizes that what is most impressive about Fastenal is its ability to disrupt itself. Over the past decade, Fastenal has closed approximately 40% of its branches (from nearly 3,000 down to about 1,700), while simultaneously raising the revenue contribution of onsite locations from roughly 10% to 40%.
Evolution of the Three Service Models:
| Model | Description | Revenue Share | Key Data |
|---|---|---|---|
| Traditional Branch | Local retail/distribution point | ~50% | ~1,700 locations, monthly revenue ~$200,000 |
| Onsite | Full-time Fastenal employees stationed at customer factories | 40% | ~2,000 sites, monthly revenue ~$100,000 |
| Automated Replenishment (Fast Bins/Vending Machines) | RFID/Bluetooth-sensed automated restocking | 40% (included above) | Largest industrial vending supplier |
"Fastenal believes there may be no branches in the future — only onsite sites and distribution centers." Its international business (17% of revenue) already operates under this model, as it started from scratch.
Three Service Pillars:
1. Expertise: Onsite personnel attend customer internal meetings, solving procurement/supply chain issues in real time
2. Inventory: Customized inventory placed at or near customer sites, remaining on Fastenal's balance sheet until the customer takes possession
3. Technology: RFID bins, vending machines, Fast Crib (on-site managed mini-warehouses), and data analytics services
Delian Entchev notes that Fastenal's organic growth has consistently outperformed the industrial economy it serves by approximately 5-6 percentage points. Over the past decade, nominal growth in the U.S. industrial economy has been around 2-3%, while Fastenal's organic growth has averaged approximately 8-8.5%.
Sources of Growth:
Financial Discipline:
Cyclical Risk: Revenue is indeed cyclical (organic growth was only 2% in 2016, and is expected to be 3-4% in 2024), but it has never turned negative since the Global Financial Crisis. Profit margins are extremely stable. A conservative balance sheet ensures that cycles do not impair long-term value.
Delian Entchev shared two key lessons:
1. The value of honest communication. Fastenal's management openly discussed sales process issues, sales team personnel changes, and the impact of branch network closures during quarterly conference calls. "Every business makes mistakes. When the stock price tells you that you're wrong, honest feedback helps us distinguish between cyclical issues and structural problems, allowing us to stick with the right investment decisions."
2. The value of field research. Flying from Sydney to Winona, Minnesota (then driving another 3 hours from Minneapolis), spending at least half a day each time communicating with management and visiting distribution centers. "The CFO told us that only ten to twenty investors are willing to visit each year. This is a S&P 500 company with a market cap of $45-50 billion." This "scuttlebutt" approach led to a deeper understanding of the company's culture and service.
| Position | Analyst Stance | Key Data |
|---|---|---|
| Fastenal | Bullish (long-term hold) | Market cap ~$50B, revenue ~$8B; EBIT margin 20%; return on capital >30%; organic growth 8-8.5%/year |
| Amazon | Mentioned (as a customer case) | One of Fastenal's largest global customers, accounting for a low-single-digit percentage of revenue |
| Grainger | Mentioned (as a competitor comparison) | EBIT margin 10-15%, broader SKU range |
| MSC Industrial | Mentioned (as a competitor comparison) | EBIT margin 10-15% |
1. "Fastenal is not a distributor; it is the customer's procurement outsourcing department." — Delian Entchev. It helps customers manage inventory, analyze usage data, and eliminate waste, allowing customers to focus solely on production. Amazon's warehouses rely on Fastenal to keep cleaning supplies and conveyor belt parts in stock.
2. "Frugality is not stinginess—it allows Fastenal to operate in small markets where competitors cannot be profitable." — Delian Entchev. Winona has a population of 26,000, yet Fastenal maintains multiple branches there; 50% of U.S. revenue comes from cities with fewer than 500,000 residents. High profit margins are reinvested into technology and infrastructure, creating a virtuous cycle.
3. "Over the past decade, Fastenal has closed 40% of its branches—it dares to disrupt its own successful model." — Delian Entchev. The shift from branches to onsite locations has seen the latter's revenue share rise from 10% to 40%. The company believes the future may hold no branches, only onsite sites and distribution centers.
4. "Of the 120 new accounts added each year, 72% have no business with Fastenal five years later, and only 2% grow into meaningful long-term accounts." — Delian Entchev. Fastenal is highly selective in choosing customers; if a customer does not spend enough, it will remove vending machines or onsite personnel.
5. "Fastenal's EBIT margin is 2-3 times that of other industrial distributors and has remained nearly a straight line over the past decade." — Delian Entchev. Grainger and MSC Industrial are around 10-15%, while Fastenal is consistently at 20%. This discipline comes from serving only customers willing to pay for the service.
6. "Even during economic downturns, Fastenal's revenue has never posted negative growth since the Global Financial Crisis." — Delian Entchev. In 2024, the PMI contracted for 22/23 consecutive months, yet Fastenal still expects 3-4% organic growth. A conservative balance sheet (zero net debt) ensures that cycles do not impair long-term value.
7. "95% of branch managers and above are promoted internally—this is a company that cultivates its own people." — Delian Entchev. Founder Kierlin wrote that "ordinary people can do extraordinary things when given the opportunity." New employees have a high turnover rate in the first 1-3 years, but once they stay, they typically work for 30-40 years.
8. "The CFO told us that only ten to twenty investors visit Winona each year—this is a $50 billion market cap S&P 500 company." — Delian Entchev. On-the-ground research (flying in from Sydney) provided a deeper understanding of the culture and service, helping to hold the position through difficult times.
