TX08 6-Lobe Pin TX Pan Head Self Drill Security Screws
Pan head self-drilling security screws on the 6-lobe pin TX drive, No.8–No.14 as tabulated (4-40, 8-32 and No.6 marked CALL in the source and not tabulated): head diameters 7.9–12.3 mm, head heights 3.0–4.2 mm, tool sizes TX20–TX30.

Specifications
TX08 is the pan-head take on the self-drilling pin-TX screw: the same drill-and-tap-in-one-pass point and the same pin-blocked six-lobe drive as TX07, but with a low dome head that needs no countersinking — the faster seating choice on thin sheet where a flush finish is not required. The collected tabulation covers No.8 through No.14 cleanly (head diameters 7.9, 9.3, 10.5 and 12.3 mm; head heights 3.0, 3.2, 3.9 and 4.2 mm; tool sizes TX20, TX25, TX27 and TX30); the source marks the 4-40, 8-32 and No.6 columns CALL, so those are not tabulated here. The design is classed for medium-torque applications with medium security against vandals and thieves at relatively low cost, and like the whole line it pairs with pin-TX barrel nuts, wave nuts, shear nuts, Kinmar nuts or four-hole nuts where the assembly needs a second layer of security. The collected availability matrix carries no legible markings, so lengths are confirmed at quotation.

Frequently asked questions
Pan or countersunk self-driller — how do I choose?
By the hole you are willing to prepare and the profile you can accept. TX08 drives straight into a flat face — no countersink cut, faster on long panel runs — but the dome stands proud by the tabulated head height (3.0 mm at No.8, 4.2 mm at No.14). TX07 seats flush but needs the countersink machined or punched into the panel. On painted architectural panels where flushness matters, TX07; on ducting, trays and internal frames where speed wins, TX08.
Can I get machine-thread sizes like 4-40 or 8-32?
The collected table lists 4-40 and 8-32 columns but marks them CALL, together with No.6 — the source publishes no dimensions for them. This page tabulates only the clean sheet-gauge columns No.8 through No.14. If a machine-thread security self-driller is genuinely needed, that is a quotation enquiry, not something to order off this page.
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.
