Frequently Asked Questions
Q: What makes left-hand thread screws different from standard screws?
A: Left-hand thread screws are designed to tighten in the counter-clockwise direction. This is intentional for drill chuck adapters — as the drill spins clockwise, the screw naturally stays locked in place rather than loosening, making your drill setup safer and more secure during use.
Q: Which drill chuck adapters are these M5/M6 fixing screws compatible with?
A: These left-hand thread fixing screws are designed for UNF (Unified National Fine) standard drill chuck shank adapters used with common electric drills. The M5×22mm and M6×22mm sizes cover the most widely used adapter thread sizes — check your adapter's specifications to confirm the correct size before ordering.
Q: Do I get both M5 and M6 screws in this 6-piece set?
A: The set contains 6 screws in the M5×22mm and M6×22mm sizes. Please check the specific listing variant you select to confirm the exact size combination included, as configurations may vary.
