## Long description

NEO tools spline socket adapter 1/2" to 18mm (model 08-590) is a compact drive accessory that converts a 1/2-inch ratchet or breaker bar into an 18 mm spline-drive connection.

The adapter provides a reliable mechanical interface between a 1/2" drive and 18 mm spline sockets, maintaining torque transfer and alignment under load. Its compact size and precise fit reduce play and slippage when working with spline fasteners. Manufactured to match common workshop tolerances, the adapter simplifies socket changes and reduces the need for multiple drive tools.

How to use
Attach the adapter to the 1/2" drive of a ratchet, breaker bar or other compatible tool until it seats securely. Connect an 18 mm spline socket to the spline output and ensure the fit is fully engaged before applying torque. Use steady, controlled force when loosening or tightening fasteners and verify that the adapter and socket remain aligned during operation.
Usage recommendations
Inspect the adapter and mating sockets for wear or damage before use. Use appropriate torque settings for the fastener and avoid sudden impacts that exceed hand-tool ratings. Clean and lightly lubricate contact areas if corrosion or dirt impedes fit; store the adapter in a dry place to maintain dimensional integrity.
