Nylon Insert Locknut Program

Manufacturing Innovation

A domestic manufacturing proposal for nylon insert and thin nylon insert locknuts in carbon steel, 18-8, and 316 stainless. US-made from domestic melt and pour, DFARS-qualifying and built to applicable Military Standards where applicable. Quoted across two production processes with a 24-36 weeks lead time.

Program Overview

What We Are Quoting

Two product categories, three materials, two manufacturing processes. 86 cold-formed line items across the full size range, plus 36 small-diameter items available on domestic screw machines.

🔩

Nylon Insert Locknut

Full UNC/UNF range, 2-56 through 1"-12. Carbon (cadmium & zinc yellow), 18-8 stainless, and 316 stainless.

⚙️

Thin Nylon Insert Locknut

Low-profile variant across carbon and 18-8 stainless in the common production sizes.

📐

Two Processes

Cold forming for the full line; Davenport screw machining for parts up to 3/8 in carbon and 304. Both fully domestic.

How We Make Them

Two Manufacturing Paths

Cold Formed: US material drawn and cold-headed into blanks, then tapped, plated, nylon-inserted, and closed. Best across the full size range and highest volumes.

Davenport: Screw-machined from hex bar in our own shop for parts up to 3/8 in carbon and 304. Lower minimums, ideal for faster and smaller runs.

Both paths are fully domestic, from domestic melt and pour, DFARS-qualifying and built to applicable Military Standards where applicable.

Program Value at MOQ

Combined Order Scenario

If the Davenport-eligible parts run on our domestic screw machines and the balance is cold-formed (no overlap), the total program value at minimum order quantities is:

ProcessLine ItemsTotal $ at MOQ
Davenport   Machined parts (≤3/8 carbon & 304)36$357,114
Cold Formed   Cold-formed remainder50$881,763
Combined program at MOQ86$1,238,877
If the entire line is cold-formed instead (no Davenport), the headed program totals $1,531,434 across all 86 items. The combined scenario lowers minimums on the small sizes by running them domestically.
Totals are at minimum order quantity, not annual or forecast volume. Lead time 24-36 weeks.
