Match the 3/8 in hex bit to the connector or bolt recess. Clear dirt from the recess so the bit can engage fully.
Use a compatible 1/2-inch square-drive tool or adapter. Verify that the retention feature is properly engaged.
Installation & Care
Check the available space around the connector as well as the fastening depth. Keep the bit aligned with the recess during use.
Inspect the hex corners and square drive for wear or cracks. Follow the connector maker’s installation procedure and replace damaged accessories.

Important Product Questions
What does the fastening depth mean?
The listed hex fastening depth is 1-3/4 inches. Check it against the depth of the connection and the space around the socket body.
Can I use it with a hand ratchet?
Yes. This hex bit socket is listed for both hand and power tools with a compatible 1/2-inch square-drive connection.
Can I use a nearby hex size?
Use the size specified for the fastener or connector. A loose fit can damage the recess, even when two nominal sizes are close.
