Jonnesway screwdriver spline XZN bit M10×30mm 6-point 10mm D10M30M10A

Jonnesway screwdriver spline XZN bit M10×30mm 6-point 10mm (model D10M30M10A) is a single-piece replacement bit designed for driving spline (XZN) fasteners and 6-point fittings. With a 30 mm working length and a 10 mm tip diameter, this bit is intended for use in automotive repair, mechanical maintenance and assembly tasks. It fits standard bit holders, ratchets and compatible power drivers, providing a direct interface with spline-head screws where precise engagement is required.

Advantages

The bit is manufactured to provide accurate engagement with spline/XZN profiles, reducing cam-out and wear on both the fastener and the tool. Its 6-point tip geometry ensures even contact with mating fasteners, improving torque transfer and stability during use. The 30 mm length offers reach for recessed fasteners while remaining compatible with common bit holders and hand tools.

Suitable for

• Automotive repair and engine assembly where spline/XZN fasteners are used
• Mechanical maintenance and equipment servicing requiring 6-point engagement
• Assembly lines and workshops using bit holders, ratchets or power drivers
• Tight or recessed fasteners that need a 30 mm bit length for access

Key specifications

• Bit type: spline (XZN) with 6-point tip geometry
• Size: M10 (spline profile)
• Tip diameter: 10 mm
• Working length: 30 mm
• Compatibility: standard 1/4" hex bit holders, ratchets and compatible power drivers (subject to tool adapter)
• Intended applications: automotive, mechanical repair, assembly tasks

How to use

Select a compatible bit holder or driver that accepts the spline bit. Insert the Jonnesway M10×30mm spline bit securely into the holder, ensuring correct seating before applying torque. Engage the spline/XZN fastener with the bit tip and apply steady, even torque using a ratchet, driver or power tool as appropriate for the fastener and application. Inspect the fastener and bit for proper fit to avoid rounding the profile.

Usage recommendations

Use appropriate torque settings and hand-start fasteners where possible to prevent damage to spline profiles; for power tool use, select lower speed and controlled torque to maintain tool and fastener life.
