Screwdriver bit NEO tools 10-904 — 12-spline flange bit, size M12

NEO tools 10-904 is a set of two 12-spline flange screwdriver bits engineered for M12 fasteners. Each bit has a spline tip sized M12 and a length of 30 mm, manufactured from S2 steel for strength and durability. The flanged spline profile ensures positive engagement with 12-spline screws and bolts, enabling accurate torque transfer when used with compatible drivers and impact tools. This two-piece set is intended for professional assembly, maintenance and repair tasks where M12 12-spline connections are present.

Advantages

The two-piece NEO tools 10-904 set provides a precise fit to M12 12-spline fasteners, reducing cam-out and wear on both the bit and the screw head. S2 steel construction offers improved toughness and resistance to deformation under high torque. The 30 mm tip length balances reach and control, making the bits suitable for confined spaces while maintaining stability during use. Being a compact set, it is convenient to store and integrate with existing bit holders or impact driver adapters.

Suitable for

• Automotive repair and assembly involving M12 12-spline screws and bolts
• Maintenance and servicing at professional car shops and service stations
• Mechanical assembly tasks where spline fasteners require accurate torque transfer
• Electronics and equipment repair where M12 spline attachments are used

Key specifications

• Tip type: 12-spline flange (spline tip)
• Size: M12
• Tip length: 30 mm
• Material: S2 steel
• Set quantity: 2 pieces
• Compatibility: for use with compatible bit holders, drivers and impact tools

How to use

Insert the M12 spline bit into a compatible bit holder or driver and ensure it is fully seated. Align the flange tip with the 12-spline fastener and apply steady axial pressure while turning the driver or activating the impact tool. For loosening, apply controlled reverse torque to avoid rounding the fastener. After use, inspect the tip for signs of wear and store the bits in a protective holder to maintain tip geometry.

Usage recommendations

Use the bits with drivers or impact tools rated for spline fasteners and select appropriate torque settings to prevent damage to fasteners and bits. Avoid excessive side loading and replace bits when the spline profile shows noticeable wear. Keep bits clean and free of debris to ensure reliable engagement with M12 12-spline screws and bolts.
