Specifications
The self-tapping member of the pin-TX line cuts its own thread in sheet metal and plastic — no nuts, no pre-tapped holes — while keeping the pin-TX drive: six lobes around a centre pin, opened only by the matching driver, reusable where maintenance is expected. The collected tabulation covers sheet gauges No.2 to No.14, with head diameters from 4.3 mm to 10.5 mm and driver sizes from TX6 to TX27. Two readings of the table matter at purchase time. First, the collected legend states this SKU ships as a pan head rather than the button head its name suggests — plan the head envelope accordingly. Second, length availability is legible only where the source marks it: No.2 is marked available to order in 3/16"–1" (4.5–25 mm) lengths and No.7 in 1/4"–2 3/4" (6.5–70 mm); the remaining gauge columns carry no legible markings and are confirmed at quotation. As with the whole line, the fixing is classed medium security — it stops casual tampering with ordinary tools, not a determined attack with the right driver.

Frequently asked questions
Why does the table show a pan head for a button head SKU?
The collected page carries an explicit legend note that the pan head is supplied on this SKU rather than the button head. That is a real sourcing detail, not a formatting quirk: a pan head stands a little taller and flatter than a button profile at the same gauge — compare the tabulated No.8 head at 7.6 mm diameter by 2.2 mm high. If the flush or low profile of a true button head is a design requirement, state it on the RFQ and confirm the supplied head form before ordering.
What length can I get in which gauge?
Only what the collected matrix actually marks: No.2 in 3/16"–1" (4.5–25 mm) and No.7 in 1/4"–2 3/4" (6.5–70 mm), both as available to order. The other six gauge columns — including the common No.8 and No.10 — print no legible markings in the collected table, so their length availability is a quotation question, not something this page invents.
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.
