Precision Shoulder Bolts for Pivot and Bearing Applications
Shoulder Bolts
Bolts with an unthreaded precision shoulder between the head and the threaded portion — the shoulder acts as a bearing surface, pivot axis, or exact stop-point for linkage, pulley, roller, and hinge assemblies.
Available for pivot and bearing applications where a precision-ground shoulder diameter with defined tolerance is specified by the customer drawing.
Why source through Way Fast
We serve Tier 1 and Tier 2 automotive suppliers — primarily to North American OEM programs, including platforms shared with European and Japanese brands — with day-to-day experience handling the documentation and tolerance standards these projects demand.
01 · Multi-source capacity
Working with multiple qualified manufacturing partners — we match each order to the best-fit production line, stabilizing lead times and cost when single-source capacity tightens.
02 · Submission-grade documentation
Full support for PPAP (Levels 1–3), IMDS submission, and RoHS / REACH documentation.
03 · Audited special-process chain
Partners certified to AIAG CQI-9 (heat treat), CQI-11 (plating), and CQI-12 (coating) — covering the full post-processing chain under audited special-process controls.
04 · Multilingual drawing review
Technical drawing review in English, German, Japanese, and Chinese — including ISO 8015 GPS callouts, JIS standards, thread tolerance classes, and coating specifications.
05 · Specification-matched supply
Shoulder diameter, tolerance, shoulder length, and thread spec matched to customer drawing — supplied per programme requirements. Contact with full shoulder tolerance spec (typically h7–h9 per ISO 7379 / ANSI B18.3) and application context for feasibility assessment and manufacturer selection.
