Specifications
TX20 moves the pin-TX principle into plastics and other soft materials: a thread-forming screw that roll-forms its own mating thread in a pre-drilled or moulded hole — no chips, no cutting debris, and a plastic-friendly fixing that can be removed and reinstalled for maintenance without chewing the boss. The collected tabulation runs M3 to M6, with thread diameters from 5.3 mm to 10.5 mm, head heights from 2.3 mm to 4.2 mm, and driver sizes in the TT series — TT10 at M3 stepping to TT30 at M6 — reflecting the Torx-family tooling this SKU is driven with. The drive is the standard pin-TX arrangement: medium security against casual tampering at low cost, reusable two-way, with the six-lobe engagement reducing slippage and cam-out compared with Phillips or two-hole drives. The collected page states A2 stainless steel or steel with zinc or black zinc finish as the material lines, and non-standard sizes or finishes as available to order including parts made to drawings. The collected availability matrix carries no legible markings, so length availability is confirmed at quotation. Typical ground: electrical housings, appliance assemblies and any moulded enclosure that must still open for service.

Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (TX20 6-Lobe Pin TX Pan Head Thread Forming Security Screws) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 10,000 pieces. Stock items run 3–7 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
Thread forming versus thread cutting in plastic — why does it matter?
Forming rolls the plastic aside instead of cutting it, so the boss keeps its material continuity — higher strip torque, no chips to contaminate the assembly, and better performance across repeated servicing. That is why the collected page points this SKU at plastics and soft materials with a pre-drilled or moulded hole. The pilot diameter is the critical dimension: too small and the boss cracks from hoop stress, too large and the formed thread is shallow. Confirm pilot sizing against the moulding at quotation.
Why TT tool sizes instead of TX?
The collected table lists driver sizes TT10 through TT30 for this SKU — a Torx-family tool series tabulated separately from the TX sizes used by the machine and self-tapping pages in this batch. Practically it means the driver for TX20 is not automatically the driver for the same nominal Torx number elsewhere in the line; keep the drive callout per SKU on the RFQ and order bits against the designation you are buying.
What is the MOQ and lead time for these security screws?
Minimum order quantity is 10,000 pieces per item. Stocked sizes ship in 3–7 days; sizes quoted as available to order, and non-standard sizes or materials, are quoted with a confirmed schedule. Confirm the exact schedule against quantity and size mix at quotation.
What should an RFQ for these security screws state?
State the designation code (TX01 through TX20) and head style, the drive (6-lobe pin TX — the matching pin-TX driver or bit is required), nominal thread size and length, material and finish, the substrate or mating nut where relevant, required certificates, and quantity per size — plus destination country.
