The Long Black Oxide Torx Key Set for Standard and Tamperproof Star Screws
Nine long Torx star keys covering T10, T15, T20, T25, T27, T30, T40, T45 and T50 - the sizes on cars, motorbikes, appliances and household fittings - with long arms from 68mm to 167mm, in one friction clip holder with clear size markings.
Security holes on both ends
Tamperproof Torx screws carry a centre pin that blocks ordinary keys. Every key in this set has the security hole on both the short and long arm, so it drives pinned and plain Torx screws alike - tighten or loosen from whichever arm the space allows.
Reach further, turn harder
Long arms from 68mm to 167mm reach recessed Torx screws a stubby key cannot touch - and the longer the arm, the more torque it puts through a stubborn or seized fixing. Reach with the long arm, then spin the screw home fast with the short one.
Industrial CR-V steel, twin-layer finish
Each Torx key is forged from chrome vanadium steel and heat treated to resist twisting and wear under torque. The black oxide finish is sealed under a clear high-gloss enamel, giving lasting corrosion resistance with a deep black look. Chamfered tips on both arms guide each key cleanly into the star recess. Keys arrive under a light protective oil film - wipe it off before first use and store the set dry.

Care and use
Wipe the protective oil film off before first use and keep the keys clean and dry. Apply light oil before long-term storage. Always match the key size to the screw - a loose fit damages the star recess.
