Screwdriver Bit Set BAHCO 1/4" drive, 3 mm hex, 25 mm length, 5 pcs in plastic box

BAHCO 1/4" drive screwdriver bit set includes five 3 mm hex bits with a 25 mm working length, supplied in a compact plastic storage box. The set is designed for use with 1/4" bit holders, manual drivers and compatible impact drivers where short 25 mm bits are required for reach and control. Constructed from high-performance alloy steel with a protective zinc phosphate finish, these bits are intended for general assembly, maintenance and precision fastening tasks with hexagonal head screws.

Advantages

The bits provide consistent fit in 3 mm hex screw heads and a secure 1/4" drive connection for most standard bit holders. The 25 mm length offers improved accessibility in confined spaces compared with longer bits while maintaining adequate engagement depth. The alloy steel construction and surface treatment improve wear resistance and reduce corrosion in normal workshop conditions. The plastic box keeps the five bits organized and protected during transport and storage.

Suitable for

• Assembly and disassembly of small machinery and equipment
• Maintenance and service tasks on appliances and electronics
• Precision fastening in carpentry, metalwork and joinery
• Use with 1/4" bit holders, manual drivers and compatible impact drivers
• Work in confined or recessed areas where a 25 mm bit length is advantageous

How to use

Select a 3 mm hex bit from the plastic box and insert its 1/4" drive end into a compatible bit holder, manual driver or impact driver until it locks. Align the hex tip with the screw head and apply steady pressure while turning to engage the fastener. For impact drivers, ensure the bit and driver are rated for impact use and apply controlled short bursts. After use, clean debris from the bit tips and return the bits to the plastic box to prevent loss and protect the tips.

Usage recommendations

Use the 25 mm 3 mm hex bits for tasks that require access into tight spaces or recessed fasteners. Match bit size precisely to the screw head to prevent rounding. For high-torque or continuous impact applications, verify compatibility of both bit and driver with impact-rated accessories and consider using a magnetic bit holder to improve retention.
