Spline socket bit 1/2" M16 x 100 mm long, NEO Tools 08-746

Spline socket bit 1/2" M16 x 100 mm long from NEO Tools is a long-reach spline bit designed for driving and removing M16 spline fasteners. The 100 mm length gives extra access into recessed or confined areas while the 1/2" square drive fits common ratchets, torque wrenches and breaker bars. The tool is intended for mechanical, automotive and industrial maintenance tasks where a precise engagement with spline-profile fasteners is required.

Advantages

The spline design provides multiple contact points to reduce rounding of fastener corners and to transmit torque more evenly. A 1/2" drive interface ensures compatibility with a wide range of hand and powered drive tools. The extended 100 mm length allows access to bolts and nuts located in deep housings or behind obstacles, improving reach without needing adapters. Constructed to meet typical workshop durability requirements, it supports repeated use in maintenance and repair environments.

Suitable for

• Accessing and turning M16 spline fasteners in tight or recessed locations
• Automotive repair and suspension work requiring deep access
• Mechanical assembly and maintenance where spline profiles are used
• Industrial equipment servicing where extended reach is necessary

Key specifications

• Drive size: 1/2" square drive
• Bit profile: M16 spline
• Overall length: 100 mm
• Application: manual and compatible powered drive tools (ratchets, breakers, impact wrenches)

How to use

Select a compatible 1/2" drive tool, seat the spline socket bit fully onto the M16 spline fastener ensuring correct alignment, and apply steady torque. For initial loosening of seized fasteners, use controlled force and, if needed, apply penetrating lubricant and allow it to work before applying higher torque. When using impact tools, confirm the bit and tool are rated for impact use and maintain firm control to prevent slipping. After use, inspect the bit for wear and clean any debris to prolong service life.

Usage recommendations

Use the spline socket bit with tools matched to the 1/2" drive and avoid applying torque beyond the tool or fastener ratings. For reuse and safety, replace the bit when significant wear or deformation of the spline profile is observed.
