The sourcing reality: lead times, distributors & the 10% line item

The cleanest fastener selection in the world is useless if you can't get the part in time or afford it. Sourcing is a first-class selection constraint, not an afterthought.

Fasteners are a real cost line

On a structural assembly, fasteners are not a rounding error — they can approach 10% of unit cost once you count the high-value structural blind bolts and lockbolts. And pricing is wildly non-linear: a single grip length can cost several times its neighbor, for reasons that have nothing to do with the part being harder to make and everything to do with volume and stocking.

Lead time is a design input

Specialty blind bolts in titanium routinely run months out, and supply-chain shocks have wiped out meaningful fractions of available capacity. A part that's perfect on paper but 9 months out forces a redesign or a premium buy. Mature programs design to available inventory — which is why the selector flags lead-time risk and surfaces alternates.

You buy through distributors, not manufacturers

Monogram, Cherry, and Howmet make the fasteners; stocking distributors — Peerless, Incora, Boeing Distribution, Würth, FDH Aero — hold the inventory, manage min/max, and carry the AS9100 traceability. They're relationship businesses, not e-commerce. A clean, spec-complete RFQ is worth a lot to them because it cuts their quoting overhead.

How the tool helps

Every family shows its lead-time risk and the distributors that stock it, and the "Request a quote" button assembles a spec-complete RFQ you can send straight to them. Knowing the price-by-grip curve before you commit is where the real money is saved.
