Screwdriver Bit GRAPHITE T20 × 50 mm model 57H986, Torx T20 tip, 50 mm length

GRAPHITE screwdriver bit model 57H986 features a Torx T20 tip and a 50 mm overall length, made for use with manual screwdrivers and powered drivers that accept standard bit holders. The bit is manufactured from hardened steel to provide accurate fit and reliable torque transfer when engaging T20 fasteners. Its compact size and straight shank make it suitable for confined spaces and routine assembly, repair and maintenance operations.

Advantages

The hardened-steel construction improves wear resistance and maintains tip geometry under repeated use, reducing cam-out and deformations. The 50 mm length balances reach and control, allowing access into moderate recesses while retaining torque feedback. Its Torx T20 tip ensures secure engagement with matching fasteners, which helps speed up fastening tasks and minimizes damage to screw heads. The bit’s standard shank fits common bit holders and quick-change chucks used in workshops and on job sites.

Suitable for

• Assembly of small-to-medium-size components with T20 fasteners
• General home repairs and maintenance tasks
• Workshop and professional repair work requiring repeated Torx fastening
• Use with cordless screwdrivers, electric drivers and manual bit handles

Key specifications

• Tip type: Torx T20
• Overall length: 50 mm
• Material: hardened steel tip
• Shank style: straight standard bit shank for quick-change holders
• Intended use: manual and powered screwdrivers with bit holders

How to use

Insert the bit into a compatible bit holder or quick-change chuck until it seats securely. Align the Torx T20 tip with the fastener recess and apply steady axial pressure while turning the driver at appropriate speed or torque setting. For removing screws, reverse the rotation and maintain alignment to avoid stripping. After use, inspect the tip for wear and store the bit in a holder or case to protect the geometry.

Usage recommendations

For best results, match the Torx T20 bit to correctly sized T20 fasteners, avoid excessive torque that can deform the tip, and regularly check the bit for rounded edges. Use appropriate torque settings on powered drivers and replace the bit when tip wear affects engagement.
