Screwdriver Bit Set Forsage F-4156C — Torx T20–T55, 15 pieces, lengths 30 mm and 75 mm

Forsage F-4156C is a 15-piece screwdriver bit set containing Torx sizes T20, T25, T27, T30, T40, T45 and T55 in two lengths: 30 mm and 75 mm. Designed for use with hand drivers and bit holders, this set provides a selection of Torx bits for assembly, repair and maintenance tasks on machinery, automotive fasteners and equipment where Torx heads are specified. The combination of shorter and longer bits helps reach recessed fasteners and work in confined or deeper locations.

Advantages

The set brings together commonly used Torx sizes in a compact kit, allowing quick selection of the correct bit without purchasing individual pieces. Two lengths increase versatility for both shallow and recessed fasteners. Bits are intended for use with standard bit holders and hand drivers to extend reach and access; the organized set simplifies storage and transport.

Suitable for

• General assembly and disassembly of Torx fastened components
• Automotive repair and maintenance where Torx fasteners are present
• Machinery and equipment servicing requiring varied bit lengths
• Electronics and appliances with Torx-head screws (where manual bits are appropriate)
• Workshop use for technicians and DIY projects involving Torx screws

Key specifications

• Total pieces: 15 screwdriver bits
• Bit type: Torx
• Included sizes: T20, T25, T27, T30, T40, T45, T55
• Bit lengths: 30 mm and 75 mm options
• Intended use: compatible with hand drivers and bit holders

How to use

Select the Torx size matching the screw head and insert the bit into a compatible bit holder or hand driver. Use the 30 mm bits for standard, shallow fasteners and the 75 mm bits to reach recessed or hard-to-access screws. Apply steady, even torque and ensure the bit is fully seated in the screw to avoid cam-out and damage to the screw head. Change bits as needed for different sizes and lengths during the task.

Usage recommendations

Inspect bits regularly for wear and replace any with rounded or damaged tips. Use the appropriate length to maintain control and avoid over-torquing; when working on precision electronics, consider torque-controlled drivers to prevent damage.
