Self-Tapping and Thread-Forming Screws for Sheet Metal, Plastic, and Cast Materials
Tapping Screws
Self-tapping and thread-forming screws — form their own internal thread in sheet metal, plastic, die-cast, or soft alloy substrates without pre-tapping or a separate nut.
Full type range across ASME B18.6.4 and DIN 7970 / 7971 / 7972 / 7983 — Type A, AB, B, BT, BP, F, 25, and custom geometries supplied per customer drawing. Applications across automotive interior panels, HVAC ducts, appliance housings, electronic enclosures, and furniture metal frames.
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 · Screw type and substrate matching
Screw type (A / AB / B / F / 25 / BT / BP), point style, thread pitch, and material grade matched to substrate (mild steel sheet thickness, galvanized, aluminum, plastic, ductile vs brittle) — drawing-reviewed against customer joint specification. Contact with full scope (drawing, substrate spec, and target annual volume) for programme-level quotation.
Family coverage · 3 types
Common tapping screw types in production
Type A / AB
Sheet metal · sharp point
Widely-spaced threads with gimlet (sharp) point. Type A for thin sheet metal and non-ferrous materials. Type AB for slightly thicker gauges or where tighter thread engagement is preferred. Standard choice for HVAC, appliance housings, and light-gauge automotive panels.
Type B
Sheet metal · blunt point
Blunter point than Type A, with machine-screw-style thread profile. Selected for thicker sheet metal, non-ferrous castings, and applications where the blunt point prevents thread damage to the opposite face.
Type 25 / F
Hardened substrates · thread-cutting
Thread-cutting (not forming) with a machine-screw body. Used in brittle or hardened substrates (cast iron, zinc die-cast, hard plastic) where thread-forming would crack the host material. Cuts chips during installation.
