Thread Forming Screws for Plastic — Industry standard
Thread Forming Screws for Plastic are bought for a small number of well-defined jobs. These are the ones we ship them for. Stocked from 2.0 to 6.0 (screw size).
Industries that specify Thread Forming Screws for Plastic
Volume assemblyAppliance and consumer products driven at speed with power tools.
Construction & fit-outFixing board, batten, framing and trim into timber and light-gauge steel.
Sheet-metal & HVACDucting, enclosures, trunking and cladding assembled without tapped holes.
Joinery & furnitureHardware, hinges and fittings into solid timber and wood-based board.
Roofing & claddingProfiled sheet and rainscreen fixed to purlins and rails.
Typical applications
forming a thread directly in sheet, board or timber
fixing where there is no access to add a nut behind the panel
high-volume driving with a bit and a clutch-set driver
Service conditions to specify against
Marine and coastal
Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
Pilot hole
Selection is really a hole-size decision: too small and the screw snaps or splits the material, too large and it strips. The size is stated per row.
Where to use something else
Not for a joint that will be dismantled and reassembled repeatedly in the same hole — use an insert or a rivet nut instead.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Industry standard
Thread Forming Screws for Plastic (Industry standard) are a type of screws used across industrial assembly. Below is the complete size table together with material, standard and application guidance.
What Are Thread Forming Screws for Plastic?
Thread Forming Screws for Plastic are screws defined by Industry standard. They are selected by screw size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
Materials & Finishes
Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.
Specification Guides
Each size, material and standard of Thread Forming Screws for Plastic has its own reference page with the figures for that one configuration.

Pricing
Thread Forming Screws for Plastic are supplied to order. Pricing starts from approximately US$0.030 per piece for standard sizes in case-hardened steel, zinc plated; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Custom manufacturing · Made to drawing
Need a thread forming screws for plastic outside the standard range?
Dimensions, material, finish and form are specified from the drawing — a screw outside the standard range is a variation on existing tooling rather than a new design. Made by cold heading or warm forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
