Screwdriver Bit Rockforce SPLINE M12 x 30 mm L, 10 mm tip

Rockforce SPLINE screwdriver bit M12 x 30 mm L with a 10 mm tip is a replacement bit engineered for use with SPLINE-head fasteners. Manufactured to fit compatible bit holders and impact drivers, this bit provides accurate engagement with spline screws commonly found in automotive and machinery applications. The compact 30 mm length and sturdy tip dimension make it suitable for confined spaces while maintaining reliable torque transfer.

Advantages

The SPLINE geometry ensures a positive and repeatable fit with spline-head fasteners, reducing the risk of cam-out and wear. Precision machining of the tip and hardened construction deliver consistent torque transfer and extended service life under repeated use. Its standardized M12 size and 30 mm length allow compatibility with a wide range of holders and drivers, and the 10 mm tip profile provides stable contact on mating screw heads.

Suitable for

• Automotive repair and assembly
• Machinery maintenance and overhaul
• Industrial assembly lines requiring spline fasteners
• Tasks in confined or recessed fastening locations

How to use

Select a compatible bit holder or impact driver and insert the Rockforce SPLINE bit securely into the chuck or magnetic holder. Align the spline tip with the fastener head, apply steady axial pressure, and operate the driver at appropriate speed and torque settings for the fastener and material. Inspect the tip periodically for wear; replace the bit when rounding or deformation is detected to maintain secure engagement and prevent fastener damage.

Usage recommendations

Use appropriate personal protective equipment and follow tool manufacturer torque guidelines. For high-torque or repetitive impact applications, ensure the bit is rated for impact use and replace it if signs of wear appear. Store the bit in a dry, organized holder to prevent corrosion and tip damage.
