## Summary description

Long 1/2" impact spline bit socket by Jonnesway, model S16A4512, with M12 spline interface and 100 mm length. Designed for use with impact wrenches and pneumatic tools to engage spline fasteners securely. Suitable for automotive, industrial maintenance and repair tasks where extended reach and impact-rated construction are required.

## Long description

Jonnesway 1/2" impact spline bit socket M12 x 100 mm long is a purpose-built accessory for impact wrenches and pneumatic power tools. The 1/2" drive interface and M12 spline tip provide positive engagement with spline fasteners, while the 100 mm length gives extra reach for recessed or hard-to-access bolts. Constructed for impact applications, this socket is intended to withstand repeated torque pulses and deliver reliable performance in automotive and industrial maintenance environments.
Advantages
The socket’s M12 spline geometry ensures accurate fitment and reduced rounding of fastener profiles. Impact-rated heat treatment and robust material selection increase resistance to fracture and wear under frequent high-torque use. The 100 mm overall length improves access to deep-seated fasteners without compromising control or stability when used with standard 1/2" impact tools. The part’s design balances durability with dimensional precision to maintain consistent engagement over time.
Suitable for
Automotive repair and brake, suspension, or transmission service where spline fasteners are used
Industrial maintenance and machinery overhaul requiring extended-reach impact tooling
Assembly and disassembly tasks on equipment with recessed or hard-to-reach bolts
Key specifications
Drive size: 1/2" (square drive compatible with 1/2" impact wrenches)
Tip interface: M12 spline profile for spline fasteners
Overall length: 100 mm for extended reach
Intended use: impact-rated socket for use with impact wrenches and pneumatic tools
Material/treatment: hardened and heat-treated for impact service (impact-rated construction)
How to use
Select a 1/2" impact wrench or extension bar compatible with impact sockets. Fit the spline bit socket onto the wrench’s square drive until it seats securely. Position the M12 spline tip onto the fastener ensuring full engagement of the spline profile before applying power. Apply controlled impulse or steady torque as appropriate for the fastener and follow manufacturer torque specifications when reassembling critical components.
Usage recommendations
Use the socket only with impact-rated 1/2" tools and avoid hand-only extension of torque beyond recommended limits. Inspect the spline tip and drive connection for wear or deformation before use and replace the socket if cracking or excessive rounding appears. When working on safety-critical assemblies, verify fastener torque with a calibrated torque wrench after using impact tools.
