Specifications
TX30 is the small end of the pin-TX family doing a different job: instead of machine threads into a nut or tapped hole, its Type B thread forms its own path in plastic — and in some metals — from a pre-drilled or moulded hole. The Type B form carries a larger root diameter with a finer pitch than a standard tapping screw, which is what lets it work in heavier plastics without splitting the boss. The 6-lobe pin recess gives it the family’s tamper profile on what is otherwise an ordinary plastics screw: reusable two-way, medium security, driven only by the matched insert bit, with the cam-out resistance that matters when a small screw in a soft boss is easy to strip. The tabulated envelope is deliberately compact — M2, M2.6, M3 and M4, with head diameters 3.5–7.0 mm and head heights 1.3–2.6 mm, driven by TX6 to TX20 tools, and a stated size list of 4, 5, 6, 8, 10 and 12 mm lengths. One fail-closed note governs the availability matrix: its legend defines an available marker, but the matrix itself carries no marks at all, so no per-pair availability is claimed — the 4–12 mm list is the source’s stated available-sizes row, and stock status for a specific pair is a quotation step. Manufactured as standard in zinc-plated steel.

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 (TX30 6-Lobe Pin TX Pan Thread Forming Security Screw — Type B) 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
Why specify Type B thread forming instead of a self-tapping screw?
Forming, not cutting: the Type B thread displaces plastic as it goes, leaving no chips and a work-hardened, thread-tight fit in the boss. The collected page states the Type B form’s larger root diameter and finer pitch as what suits heavier materials — the formed thread has more load-bearing engagement than a coarse cutting thread of the same nominal size. The cost is that you must respect the pre-drilled or moulded hole size; forming threads generate boss hoop stress, so the host part’s hole specification is part of the design, not an afterthought.
The matrix is empty — does that mean nothing is available?
No — it means the published matrix defines an availability marker but never uses it on this SKU’s matrix. This page reports what the published data states (the 4–12 mm size list across M2–M4, zinc-plated steel standard) and refuses to invent a stock status it does not mark. Treat every size pair as confirm-at-quotation; small security screws like these are also commonly made to order in small volumes per the manufacturer’s specials note.
What should an RFQ for TX30 state?
State the designation (TX30 6-lobe pin TX pan thread forming Type B), thread size and length from the 4–12 mm list, the host plastic (or metal) and its hole diameter, zinc-plated steel or the finish you need, quantity per size — and request stock-status confirmation per pair, since the source matrix carries no marks. Include the matched TX-series insert bit in the tooling plan.
