How to use
Select a compatible 3/4" drive ratchet, breaker bar, torque wrench or impact adapter, and fit the socket onto the tool's square drive until it locks. Place the 21 mm 6-point socket fully onto the fastener, ensuring full engagement on opposing flats before applying torque. For removal, apply force in the appropriate rotation while maintaining alignment to avoid slippage. For installation, set the torque tool to the required specification and tighten according to fastener manufacturer recommendations.
Usage recommendations
Use the socket only with tools rated for 3/4" drives and appropriate torque values. Inspect the socket and fastener for wear or damage before use. Avoid using damaged sockets or applying excessive force beyond tool or fastener limits. For impact applications, verify that the socket and tool are rated for impact use; when using with torque wrenches, follow the specified torque limits for the fastener and tool.
