Specifications

TX10 carries the 5-lobe pin drive onto sheet metal and plastics: a self-tapping thread that cuts its own path under a button head, so a panel or housing gets the higher-security lobed fixing without a nut or a tapped hole. The collected tabulation runs gauges No.6 to No.12 (nominal 3.5 to 5.5 mm) with head diameters 5.7–10.5 mm and head heights 2.1–3.3 mm, with gauge-specific driver tools (F10-B to F27-B in the collected tool row). Supply is stated in A2 and A4-70 stainless steel with zinc-plated steel on request. One collected discrepancy is recorded rather than resolved: the page title and the dimension table identify a button head, while one prose sentence on the same page describes a countersunk head — the tabulated button-head line governs this page, and countersunk buyers should cross-check at quotation. The availability matrix is imperial, marked cell by cell and material-coded: No.6 marks at 1/2″, 3/4″, 1″ and 1 1/2″; No.8 and No.10 mark across 1/2″–2″; No.12 marks from 1″ upward, with the 2″–3″ tail in A4-70 only. The 5/8″ row carries no markers at all. Unmarked pairs are quotation lines, and the drive remains a reusable two-way fixing — a rare combination on a self-tapper, where most security drives are one-way.

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 (TX10 5-Lobe Pin TX Button Self Tapping 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

Is a reusable security self-tapper really possible?

Yes — that is the point of the pin drives. One-way heads like clutch refuse to back out at all, which protects the fixing but ends its service life the first time maintenance opens it. TX10 keeps the 5-lobe pin drive: the matched insert bit drives it in and out indefinitely, while everyone without the restricted bit sees an immovable screw. That makes it the standard choice for removable panels on enclosures and plant equipment where the panel is sheet metal and there is no thread to receive a machine screw.

Button or countersunk — what does the source conflict actually mean for ordering?

The catalogue title, the slug and the dimension table for TX10 all describe a button head; a single prose sentence describes countersunk. Physical dimensions are what arrive, so this page follows the table: expect a domed button head with a 2.1–3.3 mm height, and do not design a flush countersink around it. If your detail genuinely needs flush, the countersunk self-tapping TX11 on the same drive is the designated page — state the head explicitly on the RFQ either way.

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; unmarked matrix pairs, zinc-plated steel on request, and specials made to order 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 and head style, the drive (5-lobe pin TX or 7-lobe pin — matched restricted insert bits required), thread or tapping size and length, the material marker you expect (A2 or A4-70 stainless; zinc-plated steel on request), the substrate or mating part, required certificates, and quantity per size — plus destination country. If you are matching existing fixings, name the drive generation explicitly: 5-lobe, 6-lobe and 7-lobe pin bits are not interchangeable.
