Frequently Asked Questions

Q: Why do drill chuck fixing screws use a left-hand thread?

A: Left-hand thread fixing screws are specifically designed for drill chucks because the forward rotational force of the drill naturally tightens a left-hand thread rather than loosening it. This prevents the screw from backing out during normal operation, keeping your drill chuck shank adapter securely in place.

Q: Are these M5 and M6 screws compatible with all electric drill chuck adapters?

A: These M5 × 22mm and M6 × 22mm left-hand thread countersunk screws are compatible with most standard UNF drill chuck shank adapters. However, we recommend verifying your adapter's thread size and pitch before ordering to ensure a proper fit.
