Frequently Asked Questions

Why use a 3/8 inch drive from an impact driver?

3/8 inch drive sockets are a common middle size for automotive and trade work, and an adaptor lets you drive them with the impact driver you already carry instead of buying a separate impact wrench. It keeps the tool bag smaller and speeds up nut and bolt work.

Will the socket stay on during high torque work?

Yes. The spring loaded ball engages the socket detent and holds it firmly on the adaptor. The adaptor is designed for impact driver torque, so both the shank grip and the socket retention are built for the load, not just for light hand work.

Do I need a different adaptor for each socket size?

Each adaptor suits one drive size, so yes, you match the adaptor to the socket drive you want to run. Durum makes the range in 1/4, 3/8 and 1/2 inch drive, and many trades carry all three so they can run any socket from one impact driver.

Which sockets can I use with this adaptor?

The 3/8 inch drive adaptor accepts standard 3/8 inch drive sockets, which covers the common middle range of socket sizes used in automotive and trade work. Fit the socket onto the adaptor until the spring loaded ball clicks into the detent, and it will stay secure while you drive the fastener.
