Jonnesway screwdriver spline (XZN) bit M14 x 75 mm, 6-point, tip 10 mm D10M75M14A

Jonnesway screwdriver spline (XZN) bit M14 x 75 mm, 6-point, tip 10 mm D10M75M14A is a replacement spline (XZN) bit designed for precise engagement with spline-head fasteners. With a 75 mm overall length and a 10 mm tip diameter, this 6-point bit is intended to be used in combination with compatible bit holders, impact drivers, or manual handles for automotive, mechanical and maintenance work where XZN/spline fasteners are specified.

Advantages

The 6-point spline geometry ensures secure contact with matching fastener profiles to reduce rounding and slipping during torque application. The 75 mm length provides reach into recessed or partially obstructed fasteners while maintaining tool control. Manufactured to fit common bit holders, the bit offers straightforward replacement and compatibility with a range of torque tools used in vehicle repair and mechanical servicing.

Suitable for

• Automotive repair and assembly involving spline/XZN fasteners
• Mechanical maintenance of machinery and equipment using spline heads
• Workshop tasks that require extended reach to recessed fasteners
• Use with compatible bit holders, ratchet adaptors, and power drivers

Key specifications

• Spline (XZN) drive profile, 6-point geometry
• Tip diameter: 10 mm
• Overall length: 75 mm
• Shank interface compatible with standard M14 sockets/holders
• Designed for use with hand and power tools for fastening tasks

How to use

Select a compatible bit holder or adaptor that accepts the specified shank interface and insert the spline bit securely. Position the tip into the matching spline-head fastener and apply steady torque, ensuring axial alignment to avoid cam-out. For power tools, use controlled speed and appropriate torque settings; for manual use, ensure the driving tool is rated for the required torque. After use, store the bit in a dry holder or toolbox to prevent corrosion and maintain tip integrity.

Usage recommendations

Use the bit only with fasteners that match the spline/XZN profile and the stated tip diameter to minimize wear and damage. Avoid using excessive impact torque beyond the ratings of the tool or fastener. Inspect the tip for wear before high-torque operations and replace when deformation or rounding is visible.
