Socket Adapter NEO tools 1/2" to 22 mm Spline Coupler (08-594)

NEO tools spline socket adapter 08-594 converts a 1/2" drive to a 22 mm spline connection. The adapter is designed to interface between standard 1/2" ratchet handles or extensions and 22 mm spline sockets, enabling use of spline-head fasteners in repair and maintenance applications. Constructed to fit common workshop workflows, the adapter provides a compact transition between square drive tools and spline socket tooling.

Advantages

The adapter offers a direct mechanical link from a 1/2" square drive to a 22 mm spline socket, eliminating the need for separate spline-specific handles. Its compact form factor keeps access in confined spaces while retaining the leverage characteristics of a 1/2" drive. The design ensures a secure engagement with spline sockets and delivers repeatable torque transfer for installation and removal of spline-head fasteners.

Suitable for

• Automotive repair and maintenance tasks requiring spline-head fasteners
• General workshop fastening where 22 mm spline sockets are used
• Use with 1/2" ratchets, torque wrenches, and extensions

Key specifications

• Input connection: 1/2" square drive (female)
• Output connection: 22 mm spline interface (male)
• Intended use: adapter for spline sockets and 1/2" drive tools
• Form factor: compact inline adapter for hand tools

How to use

Attach the adapter to the 1/2" square drive of a ratchet, torque wrench or extension, then fit a compatible 22 mm spline socket onto the adapter's spline end. Apply torque through the 1/2" drive in the normal direction for tightening or loosening, observing the torque limits of the socket and fastener. For accurate torque application, use a calibrated torque wrench and ensure the adapter and socket are fully engaged before use.

Usage recommendations

Inspect the adapter and spline socket for wear or damage before each use. Use the adapter only with tools and sockets rated for the required torque. Avoid applying impact or pneumatic forces unless the adapter is specifically rated for such use. Store in a dry environment to prevent corrosion and prolong service life.
