TX07 6-Lobe Pin TX Countersunk Self Drill Security Screws
Countersunk self-drilling security screws on the 6-lobe pin TX drive, No.8–No.14 as tabulated (No.6 dash-celled in the source and not tabulated): head diameters 7.9–13.5 mm, head heights 3.0–4.1 mm, tool sizes TX20–TX27. Case-hardened steel with anti-corrosion plated finish, lengths 1/2"–2".

Specifications
The flush-seating self-driller of the pin-TX line: a countersunk head that disappears into the panel, a drill point that skips the pilot hole, and a solid dowel in the six-lobe drive that blocks standard Torx bits. The collected tabulation covers No.8 through No.14 — head diameters 7.9 to 13.5 mm, head heights 3.0 to 4.1 mm, tool sizes TX20 to TX27 (TX27 shared by the two largest gauges); the No.6 column is dash-celled in the source, so it is not tabulated here. The collected page states the material as case-hardened steel with an anti-corrosion plated finish and sizes No.8 to No.14 in lengths from 1/2" to 2" — the only page in this batch where the source states a length range in prose. The screw is a two-way reusable fixing rated for medium-torque applications, with the reduced cam-out of the six-lobe drive protecting tip, head and panel through powered installation. No per-cell availability markings are legible in the collected matrix, so individual length/gauge combinations are confirmed at quotation.

Frequently asked questions
Why is this the pin-TX choice for outdoor panels?
It is the only screw in this batch whose collected page states a plated, case-hardened steel construction — the standard self-driller combination for fixing to steel sections, with the corrosion protection doing the weather work and the hardness carrying the drill point. TX01 through TX05 are tabulated in A2/A4 stainless for corrosive or hygiene environments, but they need pilot holes; TX07 trades the stainless option for one-operation installation into steel. Choose by substrate and exposure, and state both on the RFQ.
Is No.6 available?
The collected table carries a No.6 column but cells it with dashes — the source publishes no dimensions for it, so this page does not either. The stated range is No.8 to No.14. If a small flush self-driller is needed, confirm No.6 directly at quotation against the source of supply rather than assuming the No.8 dimensions scale down.
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.
