Screwdriver bit Forsage 25 mm L, multi-spline 1.0x5.5 mm, 1/4" drive

Forsage multi-spline screwdriver bit, 25 mm length, spline profile 1.0 x 5.5 mm with a 1/4" (6.35 mm) hex drive. Engineered for use with manual screwdrivers, powered drivers, bit holders and impact drivers that accept standard 1/4" bits, this bit is intended for fastening and loosening spline-head fasteners commonly found in automotive repair, machinery maintenance and equipment assembly.

Advantages

The multi-spline geometry provides uniform contact with the fastener, reducing cam-out and distributing torque more evenly across the head. At 25 mm length the bit offers a balance between access in confined spaces and sufficient engagement depth. The 1/4" hex drive ensures compatibility with a wide range of bit chucks, quick-change adapters and impact-capable holders, enabling use with both hand and powered tools.

Suitable for

• Automotive repairs involving spline-head screws and bolts
• Maintenance and servicing of machinery and industrial equipment
• Assembly work where spline fasteners are specified
• Use with manual screwdrivers, cordless drivers and impact drivers that accept 1/4" bits

Key specifications

• Bit type: multi-spline (spline-profile) screwdriver bit
• Working tip size: 1.0 x 5.5 mm (spline dimensions)
• Overall bit length: 25 mm
• Drive connection: 1/4" (6.35 mm) hex shank
• Intended use: fastening and loosening spline-head fasteners

How to use

Select the correct spline tip size for the fastener and insert the 1/4" hex shank into a compatible bit holder or driver chuck until it locks. Apply steady axial pressure and appropriate torque while turning the tool; when using impact drivers, ensure the holder and driver are rated for impact use. Keep the tip aligned with the fastener to avoid slipping and inspect the bit tip for wear; replace the bit if the profile becomes rounded or damaged.

Usage recommendations

Use with matching-quality holders and drivers, and choose torque settings appropriate for the material and fastener size. Store the bit in a protective case to avoid tip damage and avoid excessive side loading to prolong service life.
