Screwdriver Bit Set DeWalt DT7373 T40 x 25 mm Torx (5 pcs)

DeWalt DT7373 T40 x 25 mm Torx screwdriver bit set includes five identical T40 bits designed for fastening tasks requiring a Torx T40 profile. Each bit measures 25 mm in length, making the set suitable for use with hand screwdrivers, bit holders and compatible power tool adapters. The bits are manufactured to meet general workshop and on-site requirements for assembly, construction and repair jobs that use T40 fasteners.

Advantages

The set provides consistent T40 engagement and repeatable fit for Torx fasteners, reducing cam-out and wear when used with a correctly sized driver. The 25 mm length offers a balance between reach and control for both recessed and surface-level fasteners. Materials selected for these bits are intended to deliver durability under regular fastening cycles and compatibility with common bit holders and adapters.

Suitable for

• Assembly of furniture and metal components using T40 fasteners
• Construction and carpentry tasks with Torx screw heads
• Maintenance and repair work on equipment requiring T40 bits
• Use with manual screwdrivers, bit holders and compatible power tool adapters

Key specifications

• Bit type: Torx T40
• Quantity: 5 pieces
• Length: 25 mm per bit
• Shank style: standard 1/4" hex for bit holders and adapters
• Intended use: general fastening tasks for T40 fasteners

How to use

Select a T40 bit from the set and insert it into a compatible 1/4" hex bit holder, screwdriver or adapter. Ensure the bit seats fully in the holder and that the tool is set to the appropriate torque or speed for the fastener and material. Apply steady pressure and maintain alignment with the screw head to avoid stripping. For power tools, use controlled torque settings and short bursts when approaching final tightening.

Usage recommendations

Inspect bits periodically for wear or damage and replace any bit that shows rounding or chipping. Use the correct T40 size and appropriate torque to preserve bit life and fastener integrity. When working with impact drivers, ensure the bit holder and driver are rated for impact use.
