Torx extra-long key set Dedra T10–T50, S2 steel, 9 pieces

Dedra Torx extra-long key set T10–T50 (9 pieces) is a professional-grade assortment designed to reach recessed and hard-to-access Torx fasteners. Manufactured from S2 tool steel, the keys combine extended length with durable tips to provide improved reach and leverage during assembly, maintenance and repair operations. The set covers common sizes from T10 up to T50, offering a practical range for automotive, electrical and general mechanical applications where standard-length keys may not suffice.

Advantages

The extra-long design increases clearance and access to fasteners located in deep or confined spaces without compromising control. S2 steel construction ensures wear resistance and tip durability for repeated use under torque. A graduated range of sizes simplifies selection for different fastener heads, while the consistent geometry of the Torx profile reduces cam-out and enables efficient torque transfer.

Suitable for

• Automotive repair and maintenance
• Electrical equipment assembly and servicing
• General mechanical and workshop tasks requiring extended reach
• Appliance repair where fasteners are recessed

Key specifications

• Sizes included: T10, T15, T20, T25, T27, T30, T40, T45, T50
• Material: S2 tool steel for enhanced hardness and durability
• Design: Extra-long shank for increased reach and leverage
• Tip profile: Torx geometry for improved torque transfer and reduced cam-out
• Quantity: 9 pieces in the set

How to use

Select the key that matches the Torx fastener size and insert the tip fully into the fastener recess to ensure correct engagement. Use the longer shank to access fasteners located deep within housings or behind obstacles, applying steady, axial torque to avoid stripping the head. For higher torque requirements, position the long arm for leverage and, where practical, use the short arm for tighter spaces while maintaining full tip engagement.

Usage recommendations

Inspect tips for wear before use and replace keys if the Torx profile is rounded. Apply torque within the tool’s intended limits and avoid using damaged keys. Clean and store the set in a dry place to prevent corrosion and maintain tip accuracy.
