Press-Fit Knurled Fasteners
Knurl Bolts
Knurled-shaft fasteners — the knurl pattern press-fits into an unthreaded hole and creates retention without tapped threads, heat-staking, or secondary fastening.
Available for specialty retention applications: plastic moulded components, die-cast brackets, thin-wall sheet anchors, and similar substrates where knurl geometry 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
Knurl pattern, pitch, and engagement length matched to customer drawing and substrate specification — supplied per programme requirements. Contact with full application context (substrate material, wall thickness, retention force target) for feasibility assessment and manufacturer selection.
