Custom Torx Screws & Non-Standard Fasteners
Send a drawing, get a production-ready fastener. Zhuhai Jiali Hardware (FASTKING) has been manufacturing Torx drive screws and non-standard fasteners for over 20 years as an ISO-certified factory — with 7 surface finishes, 304/316 stainless, carbon and alloy steel, and full control over head, drive, thread, length, coating and packaging.

ISOcertified production
Standard catalogue screws do not always fit a new design. We manufacture non-standard Torx screws and custom fasteners to drawing or to sample — from a single changed dimension on a standard part to a fully new profile. Every quotation starts with your drawing: we check feasibility, confirm the material and finish, then quote.
What we customize
Any of the following can be changed independently or together. If a dimension is not on your drawing, we will confirm it with you before production.
Head type
Pan, button, flat / countersunk, cheese, hex flange, pan-with-collar, or a custom head profile per drawing.
Drive type
Torx (6-lobe), Torx-pin (security / tamper-resistant), hex socket, Phillips, or a combined drive.
Thread
Machine screw threads, self-tapping, self-drilling and thread-forming screws — size, pitch and thread length to drawing.
Dimensions
Diameter, length, head diameter and height, under-head fillet, point type and tolerances as specified.
Material
Stainless steel 304 / 316 (A2 / A4), carbon steel, alloy steel, brass and aluminium.
Surface finish
Seven finishes, listed in the table below — selected against the base material and the corrosion level the part sees.
Patch coating
Pre-applied nylon patch or adhesive for anti-loosening, applied full-length or half-circumference as required.
Packaging
Bulk cartons, bagged or blister packs, labelled per SKU, custom carton printing for your own brand.
Surface treatment options
Finish choice drives corrosion life, appearance and cost. We recommend the finish together with the material, based on where the screw is used.
| Finish | What it is | Typical use |
|---|---|---|
| Zinc plating (clear / blue-white, yellow) | Electroplated zinc layer over carbon or alloy steel, bright appearance. | Indoor assemblies, general-purpose fastening, cost-sensitive volume parts. |
| Black oxide | Chemical conversion coating; dark surface with almost no dimensional change. | Tooling, precision mechanisms, dry indoor environments. |
| Phosphating | Porous conversion coating that holds oil well. | Parts that need lubricant retention or a paint base. |
| Passivation | Removes free iron from machined stainless surfaces and restores the oxide layer. | Machined 304 / 316 stainless parts after cutting and thread rolling. |
| E-coating | Electro-deposited organic film, uniform coverage including recesses. | Parts needing a colour finish plus corrosion protection. |
| Dacromet | Zinc-aluminium flake coating, applied without hydrogen embrittlement risk. | High-strength and outdoor parts, automotive and structural use. |
| Natural stainless | No coating; machined or passivated stainless surface. | Visible stainless assemblies, food equipment, marine-adjacent parts. |
How a custom order runs
Five steps from your file to a shipped lot. You approve the drawing and the sample before mass production starts.
- Send drawing or sample2D drawing (PDF / DWG) with material, finish and tolerance — or a physical sample with target quantity.
- Feasibility & quotationWe check tooling, material and process, then quote with lead time and packing details.
- Sample approvalSample parts are produced and sent for your dimensional and functional approval.
- Production & inspectionIn-process and final inspection; an inspection report is issued with the shipment.
- DeliveryFactory-direct shipping, with the agreed packing and labelling per SKU.
Why buyers send drawings to us
Torx specialists
Torx and Torx-pin drives are our core product, not a side line — 20+ years of forming, thread rolling and heat treatment experience.
Stock plus custom
Standard sizes ship from stock; the same team handles your non-standard parts on the same drawing standards.
Traceable quality
Incoming material verification, in-process checks and final inspection, with a report issued for each shipment.
Frequently asked questions
What is the minimum order quantity for a custom part?
It depends on the part and the process — a diameter change on an existing screw is very different from a new heading tool. Send the drawing with your target quantity and we will confirm the workable minimum in the quotation. Trial batches are accepted for first orders.
Can you produce a non-standard screw without a drawing?
Yes. Send a physical sample; we measure it, prepare a drawing with material, finish and tolerances, and send it back for your approval before any tooling is made.
What files should I send for a quotation?
A 2D drawing (PDF or DWG) showing material, thread, tolerances and surface finish, a 3D model (STEP / IGES) if you have one, the target quantity, and any packaging or labelling requirement. Photos of the mating part also help.
Which surface finishes can you apply?
Zinc plating (clear / blue-white, yellow), black oxide, phosphating, passivation, e-coating, Dacromet, and natural stainless finish. See the surface treatment table above for where each one is used.
Do you make security Torx screws?
Yes — Torx-pin (pin-in-Torx) security screws are a standard part of our range, in the head styles and lengths you specify, with or without patch coating.
