Torx T20 Long Bit Key, Dedra, CRV steel

Long Torx T20 key bit from Dedra manufactured from chrome-vanadium (CRV) steel. This long T20 bit is designed to reach recessed or hard-to-access Torx T20 fasteners while maintaining accurate engagement with the screw head. The chrome-vanadium construction provides strength and abrasion resistance for repeated use in automotive, assembly, maintenance and DIY tasks where extended reach and reliable contact are required.

Advantages

The Dedra Torx T20 long bit offers precise fit to standard T20 Torx screw profiles, reducing cam-out and fastener damage. Its extended length improves access to deep or narrow cavities without compromising torque transfer. Made of CRV steel, the bit has improved toughness and wear resistance compared with ordinary carbon steel bits and benefits from corrosion resistance suited to workshop and field use. The compact cross-section and accurate machining ensure consistent seating in the screw recess for effective turning.

Suitable for

• Automotive repair and component disassembly
• Furniture and equipment assembly where fasteners sit deep
• Maintenance and repair in confined or recessed spaces
• Hobbyist and DIY projects requiring Torx T20 fastener access

Key specifications

• Tip profile: Torx T20 compatible geometry for secure engagement
• Material: Chrome-vanadium (CRV) steel for strength and wear resistance
• Form factor: Long bit for extended reach in recessed or confined areas
• Compatibility: Fits standard bit holders, drivers and bit sockets designed for Torx bits
• Typical applications: Suitable for high-torque manual and powered drivers when used within recommended torque limits

How to use

Select the Dedra Torx T20 long bit and insert it securely into a compatible bit holder or driver. Align the Torx T20 tip with the fastener recess, ensure full seating to minimise wear and cam-out, then apply steady torque appropriate for the fastener and material. For powered drivers, use controlled speed and torque settings; for manual use, avoid excessive bending or side load on the long bit to prevent deformation. After use, clean debris from the tip and store the bit in a dry place.

Usage recommendations

Use the bit with drivers or holders that provide axial support to reduce side loading. Inspect the tip regularly for rounding or wear and replace when engagement becomes loose. For corrosion protection, keep the bit dry and remove residues after use; avoid using the bit with fasteners that require higher torque than the bit or driver is rated for.
