Torx star key set Polax 25-008, 9 pieces T10–T50, CrV, long

Polax Torx star key set 25-008 contains nine long Torx keys in sizes T10–T50 made from chrome-vanadium (CrV) steel. The set is designed to fasten and loosen Torx-headed fasteners in automotive, mechanical and assembly applications. The extended length of each key improves access to recessed screws and increases leverage for controlled torque application while maintaining resistance to wear and deformation under normal workshop use.

Advantages

The long Torx keys are manufactured from CrV steel to deliver strength and durability for repeated use. Their extended shafts enable reach into deep or obstructed screw locations while providing improved control compared with short keys. A consistent profile and precise tip fit reduce cam-out and protect fastener heads. The compact nine-piece selection covers commonly used Torx sizes from small to large, supporting a range of tasks without requiring additional tools.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and machinery servicing
• Electronics and appliance repair requiring Torx fasteners
• DIY projects and hobby work involving Torx screws
• Accessing recessed or hard-to-reach fasteners

Key specifications

• Material: chrome-vanadium (CrV) steel
• Number of pieces: 9
• Sizes included: T10, T15, T20, T25, T27, T30, T40, T45, T50
• Type: long-shaft Torx keys for extended reach
• Finish: industrial-grade heat-treated steel (corrosion resistance typical for CrV tools)

How to use

Select the Torx key that matches the screw head size and insert the key fully into the fastener to ensure correct engagement. Use the long shaft to reach screws located in recessed or obstructed positions; apply steady turning force while keeping the key aligned with the fastener axis to minimize slippage. For higher torque requirements, position the long key so that you use the longer arm for leverage and the shorter arm for clearance if needed. After use, store keys in their holder or toolbox to protect tips and maintain size organization.

Usage recommendations

Inspect key tips and fastener heads before applying high torque. Replace any key that shows significant wear or deformation to avoid damaging fasteners. Use appropriate hand tools—avoid using cheater bars or impact tools on these hand keys unless explicitly rated for such use.
