The Fastshifter TX15 × 89 mm bit is a long T15 Torx bit with an integrated depth stop, made for use inside hidden deck fastening tools. The depth stop drives every screw to exactly the same depth, so the board edge is never over-driven or crushed.
The 89 mm length is what allows the bit to reach the fixing point through the body of the tool. Supplied in a pack of 2.
Key features
- T15 Torx, 89 mm long — reaches fixing points inside hidden fastening tools.
- Integrated depth stop — consistent driving depth, no damage to the board.
- Compatible with other and Fastshifter tools.
- Hardened for a long working life at high screw counts.
- Available separately as a spare or a second bit.
- Pack of 2 pcs.
Where it is used
- Hidden edge-fix decking installation.
- Fastshifter Invisible C4 and A2 screw systems.
- High-volume professional decking work, where bits wear out.
- As a spare on site — a worn bit is the usual cause of a stalled deck build.
An essential consumable rather than an accessory: bit wear is what causes cam-out, and cam-out is what damages both the screw head and the board edge.
