Screwdriver Bit set Irwin 10504373 Torx T20 1/4" 50 mm, 5 pcs

Pack of five Irwin Torx T20 screwdriver bits with a 1/4" hex shank and 50 mm working length. These bits are intended for use with standard bit holders, impact drivers and cordless drills that accept 1/4" hex bits. The Torx T20 tip profile provides positive engagement with compatible fasteners, reducing cam-out and ensuring repeatable torque transfer for fastening and assembly tasks in woodworking, furniture fitting and general maintenance.

Advantages

The bits are manufactured to provide accurate tip geometry and consistent fit in Torx T20 fasteners, which improves driving efficiency and reduces damage to screw heads. The 50 mm length gives a balance between accessibility in recessed locations and control when used in hand-held drivers. The 1/4" hex shank ensures secure retention in common bit holders and quick-change chucks. Supplied as a set of five, they offer spare pieces for repetitive jobs and reduce downtime caused by worn tips.

Suitable for

• Fastening Torx T20 screws in furniture assembly and cabinet making
• General maintenance and repair tasks requiring T20 drive
• Woodworking projects where reliable screw engagement is needed
• Use with impact drivers, cordless drills and manual bit holders accepting 1/4" hex bits

Key specifications

• Tip type: Torx T20
• Shank: 1/4" hex
• Length: 50 mm
• Quantity: 5 pieces per pack
• Compatibility: designed for use with bit holders, quick-change chucks, impact drivers and cordless drills accepting 1/4" hex bits

How to use

Insert the 1/4" hex shank into a compatible bit holder, quick-change chuck or directly into a drill/driver designed for hex bits. Position the Torx T20 tip into the screw head ensuring full engagement before applying drive torque. When using cordless drivers or impact tools, start at low speed to seat the tip, then increase torque as needed. Replace the bit when signs of tip rounding or wear appear to maintain secure engagement and avoid damage to fasteners.

Usage recommendations

For prolonged life, avoid excessive side loading and use the appropriate torque setting on power tools. Store bits in a dry environment and replace any bit showing visible deformation or rounding of the Torx profile.
