AN Washers, Safety Washers, Jam Nuts, and Nylock Nuts
Jam Nuts, Nylock Nuts, AN Washers & Safety Washers — The Right Hardware Matters
Details count, and fastening systems are no exception. When you’re running down the track at triple-digit speeds, the right hardware should not be overlooked. At The Chassis Shop, we carry Pro-Werks specialty fasteners — those hard-to-find but correct parts that serious builders rely on. Like everything from Pro-Werks, this is the good stuff.
AN Washers — Cadmium Plated, Aircraft Spec, 100 Pack or Complete Kit
AN (Army-Navy) specification washers are precision-dimensioned flat washers used throughout aerospace and racing applications. Unlike standard hardware store washers, AN washers have a smaller outside diameter and tighter tolerances on ID, OD, and thickness — ensuring proper load distribution and correct fit under bolt heads and nuts. Made of non-hardened steel, cadmium plated (gold in color). Ideal for applications where space is limited and weight savings matter.
- AN Washers — Cadmium Plated, Individual Sizes, 100 Pack — Pro-Werks Cadmium Plated AN Washers — non-hardened steel, gold cadmium plated, AN3–AN8 sizes available
- AN Washer Kit — 100 of Each Size (AN3–AN8) in Durable Organizer Box — Pro-Werks Cadmium Plated AN Washer Kit — fits in a tool box drawer, refillable by size, all 6 sizes included
Safety Washers — Zinc Plated, CNC Machined, Sold in Pairs or Bags of 20
Safety washers (also called rod end washers) are used with rod ends and heim joints to prevent the ball of the rod end from pulling through rod end body should the body fail — a critical safety component for any suspension or steering linkage. The generous radius undercut allows for maximum rod end misalignment angle. May also be used as spacers on each side of the rod end. Precision CNC machined mild steel, gold zinc-plated for corrosion resistance. Made in USA

Jam Nuts — Grade 5 Plated Steel, RH & LH Thread
Jam nuts are thin profile nuts — half the height of a regular nut — used to lock a rod end, clevis, or tube adapter in position after adjustment. Available in right-hand (RH) and left-hand (LH) thread configurations to match your linkage setup. Essential for any 4-link bar, control arm, or steering linkage build. Conveniently packaged in moderate quantities.
- Jam Nuts — Grade 5 Plated Steel, RH & LH Thread, Multiple Sizes — Pro-Werks Plated Steel Jam Nuts, Grade 5 — positive lock on final adjustments, packaged in moderate quantities
Nylock Nuts — Grade 5 Plated Steel, Full Height & Half Height
Nylon insert lock nuts provide vibration-resistant fastening for applications where standard nuts would back off under load. Available in Full Height or Half Height versions — choose based on your load application.
- Full Height Nylock Nut — Grade 5, UNF Thread, Full Strength for Tension or Shear — Pro-Werks Plated Steel Nylock Nuts, Grade 5 — Full Height — nylon insert retention, right-hand UNF thread, use in tension or shear applications
- Half Height Nylock Nut — Grade 5, UNF Thread, Lightweight for Shear Applications — Pro-Werks Plated Steel Nylock Nuts, Grade 5 — Half Height — nylon insert retention, thinner profile saves weight, typically used in shear load applications
