"I've been buying AN hardware from Wicks for years. When I found out the same parts with 8130-3 tags were 50% less here, I switched my whole RV-9A fastener order. No complaints."
"Our shop goes through hundreds of AN4 bolts a month. The price difference adds up fast. Traceability paperwork is solid — no issues with our DER."
"Ordered on a Tuesday, shipped same day, arrived Thursday. Castle nuts and locknuts all came with the 8130-3. This is how surplus hardware should work."

Is Aerospace Spec Bolt cheaper than Wicks Aircraft Supply?
Yes. On the 22 SKUs in this comparison, we're 40–65% below Wicks list prices. We source certified surplus from military contracts and MRO overstock programs — the hardware is identical, the acquisition cost is not.
Is surplus hardware the same quality as new hardware from Wicks?
Surplus hardware sourced from overstock programs is the same hardware — made to the same MIL-SPEC by the same manufacturers. Every part we ship includes an FAA Form 8130-3 Airworthiness Approval Tag. That's the same documentation the FAA and your A&P require. The only difference is provenance: ours came from a government warehouse, not a fresh production run.
Does Aerospace Spec Bolt carry the same parts as Wicks?
For standard AN, MS, and NAS fasteners — yes. AN3 through AN6 bolts, AN310 castle nuts, AN365 elastic stop nuts, MS21042 all-metal locknuts, AN960 washers, MS24665 cotter pins — all stocked. We carry 35,000+ surplus AN/MS/NAS parts. If we don't have it, we'll tell you.
Is this legal for certified aircraft?
Yes. The FAA 8130-3 tag is the certification instrument — it documents the part's traceability to an approved manufacturer and production batch. Your A&P or IA will recognize it. EAB builders have the same access with zero additional requirements.
How do Wicks Aircraft and Aircraft Spruce pricing compare?
Wicks and Aircraft Spruce are both established general aviation retailers and price similarly on standard AN/MS/NAS fasteners. Both are reliable. Aerospace Spec Bolt undercuts both because we buy certified surplus — not new production. See our Aircraft Spruce comparison →
