Torx Pin Key (T55) 6-Point 100 mm, GEKO CRV G13487

GEKO Torx Pin Key T55 is a 6-point tool with a 100 mm shank manufactured from chromium-vanadium (CRV) steel. Designed to engage tamper-resistant Torx fasteners that have a centre pin, this T55 key delivers precise fit and stable torque transfer for automotive repair, machinery maintenance and general workshop tasks. The 100 mm length provides additional reach for recessed or hard-to-reach screws while the 6-point geometry reduces cam-out and improves contact with the screw head.

Advantages

The CRV construction combines hardness and toughness to withstand frequent use and resist wear. The 6-point Torx profile ensures secure engagement with pin-type Torx screws, minimising slippage and damage to fastener heads. With its 100 mm length, the key offers extended access to recessed fasteners and improved leverage compared with shorter drivers. The compact single-piece design is suitable for use with hand-held drivers, ratchets or handle adaptors commonly found in maintenance kits.

Suitable for

• Removing and installing tamper-resistant Torx (T55) screws in automotive assemblies
• Maintenance and repair of machinery where recessed or pinned Torx fasteners are present
• Workshop and technician tool kits requiring a long-reach T55 driver

Key specifications

• Tip profile: Torx with centre pin, 6-point
• Size: T55
• Length: 100 mm
• Material: Chromium-vanadium (CRV) steel
• Finish: industrial heat-treated/tool steel finish (factory applied)

How to use

Select the T55 Torx pin key when the screw head matches the T55 pinned Torx pattern. Insert the tip fully into the screw recess ensuring the centre pin seats correctly in the driver cavity, then apply steady axial pressure while turning to avoid cam-out. Use with an appropriate handle, bit holder or ratchet adapter; avoid excessive torque beyond the fastener or tool rating to prevent tip deformation. Keep the tip clean and free from debris for accurate engagement.

Usage recommendations

For best results, inspect both driver tip and fastener for wear before use. When working in confined or recessed areas, use a bit holder with minimal play to maintain alignment. Store the Torx pin key in a dry tool tray to prevent corrosion and extend service life.
