Federal Supply Class
Federal Supply Class 5310 — Nuts and Washers — clustered reference parts from bounded catalog scan. Classification does not certify fit-for-purpose, interchangeability, trace sufficiency or stock readiness.
Why buyers stay
Replied to by a named sales executive
Sal Faruqui owns inbound RFQs end-to-end — no generic queue, one contact through fulfillment.
Priority review for AOG lines
Routine RFQs are reviewed promptly; AOG-marked lines bypass the routine queue and are prioritized for callback.
Documents lined up before purchase
FAA Form 8130-3, ATA-106, Certificate of Conformance, and mill-cert requirements are captured before quoting.
PUB LOG referenceEvidence-safe related rows — not stock, price, or GTIN claims. Bounded sample; always confirm particulars with procurement engineering and records teams.
