Post Torx Bits

Pin Torx (Post Torx) Security Bits
Pin Torx bits, also called Post Torx, are Torx bits with a hole down the centre so they fit over the centre pin of a Pin Torx security fastener. A standard Torx bit cannot enter the drive - only the matching pin-torx bit fits.
Bit Range
Common Pin Torx sizes (T10, T15, T20, T25, T27, T30, T40) in 25mm standard and long-shank lengths. Standard 1/4" hex shank for drill chucks, impact drivers and bit holders. The screws they drive are in Security Machine Screws and Security Self Tappers.
Recommended Use
Match the bit T-number to the fastener drive exactly. Use a magnetic bit holder to keep the screw on the bit. Replace worn bits early - a slipping bit rounds the recess and the screw then has to be drilled out.
