Screwdriver Bit Forsage 12-prong SPLINE M8×10 mm L30 mm

The Forsage 12-prong SPLINE screwdriver bit is a precision bit designed for spline fasteners. It features an M8×10 mm interface and a working length of 30 mm, made as a single replacement bit to fit standard bit holders and manual or powered drivers. This bit is intended for applications where accurate engagement with spline heads and reliable torque transfer are required, including automotive, mechanical assembly, and precision maintenance tasks.

Advantages

The 12-prong SPLINE profile provides multiple contact points for secure engagement with compatible fasteners, reducing the risk of cam-out and wear. The compact 30 mm length allows use in confined spaces while maintaining reach and control. Manufactured to fit common bit holders, the bit is compatible with both hand tools and power drivers for flexible use. The solid construction supports precise torque application and repeated use in professional environments.

Suitable for

• Automotive repairs and component assembly
• Mechanical and industrial equipment maintenance
• Precision assembly tasks requiring spline drive engagement
• Use with hand drivers and powered drivers in confined spaces

Key specifications

• Drive type: 12-prong SPLINE
• Interface size: M8×10 mm
• Overall working length: 30 mm
• Compatibility: standard bit holders and driver chucks
• Application: designed for spline fasteners and controlled torque transfer

How to use

Insert the bit securely into a compatible bit holder or driver chuck, ensuring the interface seats fully to prevent slippage. Match the 12-prong SPLINE profile to the corresponding fastener head and apply steady, controlled torque using a hand or powered driver. For powered drivers, start at low speed to ensure correct engagement, then increase speed as needed. Inspect the bit and fastener before use to confirm clean, undamaged mating surfaces.

Usage recommendations

To prolong bit life and maintain secure fastening, avoid excessive side load and use appropriate torque settings for the application. Replace the bit if the splines show signs of rounding or deformation. Keep the bit clean and store in a protective case when not in use.
