Fastenal is one of the largest industrial distributors in North America, with roughly $7 billion in annual revenue and more than 3,000 branch locations across the United States. Based in Winona, Minnesota, the company sells fasteners, tools, safety equipment, janitorial and facilities supplies, cutting tools, hydraulics, and pneumatics to manufacturers, contractors, and industrial operations. That scale creates real supplier opportunities, but getting in front of the right buyers requires more than a cold email.
Here is what you need to know to register, certify, and compete for Fastenal business.
What Fastenal buys from external suppliers
Fastenal's core product categories include:
- Fasteners (bolts, nuts, screws, anchors, rivets)
- Safety supplies (PPE, eyewear, gloves, hard hats, first aid)
- Tools and shop equipment (hand tools, power tools, tool storage)
- Janitorial and facilities maintenance products
- Cutting tools and abrasives
- Electrical and fluid power components
- Construction supplies
The company also sources private-label products and packaging under its own brands. If you manufacture or distribute within any of these categories, you are selling into a market Fastenal actively buys. The company operates on a distributed branch model, which means category managers at headquarters in Winona make vendor approval decisions, but individual branches can generate purchase orders once you are an approved vendor.
Beyond finished goods, Fastenal contracts for services related to its facilities, logistics, and professional services needs. Diverse businesses in those categories should not assume the only path in is through product sales.
How to register as a Fastenal supplier
Fastenal manages supplier onboarding through its supplier portal. To find it, navigate to the Fastenal corporate website and look for the supplier or vendor section, typically under a "Company" or "About" navigation heading. The program is branded as Fastenal Supplier Diversity, and registration instructions are available there.
During registration, expect to provide:
- Legal business name, EIN, and DUNS or SAM.gov UEI number
- Business address and contact information
- Business structure (LLC, corporation, sole proprietorship)
- Diversity certification documentation (certificate number, issuing organization, expiration date)
- Product or service categories using UNSPSC or NAICS codes
- Capability statement or product catalog
- Certificate of insurance with required coverage levels
- W-9
Fastenal uses a standardized vendor questionnaire common to large industrial buyers. Fill out every field. Incomplete submissions stall in review queues. If your certification is pending, note the application date and expected issuance date rather than leaving the field blank.
Which certifications carry the most weight
Fastenal participates in both NMSDC and WBENC, the two most recognized corporate diversity certification bodies in the United States.
NMSDC certification (MBE, for minority-owned businesses) and WBENC certification (WBE, for women-owned businesses) carry the most direct weight in Fastenal's supplier diversity program. These are the certifications Fastenal's procurement and supplier diversity teams have built relationships around, and both organizations connect certified suppliers with corporate members through matchmaking events and databases.
If you hold an NMSDC MBE certificate, you can be searched in the NMSDC supplier database, and Fastenal buyers can find you there before you ever reach out. The same applies to WBENC's WBENCLink2.0 database. These databases are how corporate supplier diversity teams fill gaps in their programs before a sourcing event forces the issue.
Other certifications worth noting:
- SDVOSB (Service-Disabled Veteran-Owned) and VOSB: Recognized in reporting and may support Fastenal's veteran business commitments
- SBA 8(a): Less directly relevant for corporate procurement but signals federal contractor credibility
- State-level MBE/WBE: Useful context but not a substitute for NMSDC or WBENC at a national buyer like Fastenal
If you are not yet certified, NMSDC certification runs through your regional affiliate council. There are 23 affiliate councils nationwide, and fees vary by revenue tier, typically ranging from $350 to $1,250 annually. WBENC certification also runs through regional partner organizations. Both processes require documentation of ownership, control, and day-to-day management.
How certification affects your chances
Fastenal's supplier diversity team tracks spend with certified diverse suppliers and reports that data publicly. That reporting obligation creates internal pressure to route purchases toward certified vendors when qualified options exist.
Practically, this means two things. First, being certified gets you onto the radar of Fastenal's supplier diversity team in ways that a cold application from an uncertified business does not. Second, when two vendors have comparable pricing and quality, diverse certification can be the deciding factor for a category manager trying to hit diversity spend targets.
Certification does not guarantee an order. Fastenal is a performance-driven industrial distributor. Fill rate, lead times, and pricing still determine whether you get reordered. But certification gets you into the conversation faster and keeps you in it longer.
Who handles supplier diversity at Fastenal
Fastenal has a dedicated supplier diversity function at its Winona headquarters. The team is typically led by a Supplier Diversity Manager or Director of Supplier Diversity, who coordinates with category managers across product lines. When you reach out, address your inquiry to the Supplier Diversity team rather than to a general procurement inbox.
NMSDC and WBENC both maintain corporate member directories. If you are a certified MBE or WBE, your regional affiliate council can often make a warm introduction to Fastenal's supplier diversity contact. That introduction carries more weight than a cold submission through the portal alone.
Tips for winning your first order
Getting approved as a vendor and getting your first purchase order are two separate milestones. The gap between them is where most diverse suppliers stall.
Start with a specific category pitch, not a general "we can supply anything" message. Fastenal's category managers own narrow product lines. Know your target category, know Fastenal's current suppliers in that category, and be prepared to articulate why your pricing, quality, or lead times compete.
Attend NMSDC or WBENC events where Fastenal participates. The company shows up at national conferences and regional matchmaking events. A five-minute conversation at a B2B matchmaking session at an NMSDC conference can compress months of portal limbo into a direct follow-up conversation with a category manager.
Build a product catalog formatted for industrial buyers. That means UNSPSC codes, unit pricing, minimum order quantities, lead times, and certificates of conformance where applicable. Sending a polished PDF or an EDI-ready catalog signals that you can operate at Fastenal's scale.
If you are a distributor rather than a manufacturer, be clear about what you stock versus what you drop-ship. Fastenal values fill rate. If your model depends on your own supplier's inventory, explain how you manage that risk.
Follow up. Supplier diversity teams at companies Fastenal's size manage hundreds of applications. A professional follow-up email 30 days after submission is expected, not pushy.
Supplier development programs and events
Fastenal does not publicly operate a formal supplier development academy the way some automotive OEMs do. The primary vehicle for supplier development is participation in NMSDC and WBENC programming, which Fastenal engages with as a corporate member.
Through NMSDC, certified MBEs can access mentoring, capacity-building workshops, and direct corporate matchmaking sessions. Through WBENC, certified WBEs can access the WBENC Business Dashboard, pitch events, and regional forums. Both organizations run annual national conferences where Fastenal's supplier diversity team participates in one-on-one meeting formats.
If you are not yet a certified member of either organization, that is the first investment to make before pursuing Fastenal directly. The certification opens the relationship-building channels that make the registration process move faster and the category conversations more productive.
