The Long 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 160mm, 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 160mm 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.
Chamfered tips, satin CR-V steel
Precision chamfered tips on both arms locate the star recess and guide the key smoothly in, even working blind behind a panel. Each key is forged from chrome vanadium steel and heat treated to resist twisting and wear, with a bright satin finish that resists corrosion and wipes clean.

Why choose this set
- Fits standard and tamperproof Torx screws with either arm
- Long arms reach recessed screws and multiply torque on stubborn fixings

Care and use
Keep the keys clean and dry, and apply light oil before long-term storage. Always match the key size to the screw - a loose fit damages the star recess.
