About This Product
Need a left-hand thread bolt for a specific project or repair?
These reverse-thread hex socket screws are what you're looking for.
They're grade 12.
This listing lets you choose from a range of metric sizes – from M3 (3mm) all the way up to M16 (16mm) diameter, and you can pick the length you need.
Thread pitches vary by size: M3 is 0.
5mm, M4 is 0.
7mm, M5 is 0.
8mm, M6 is 1.
5mm, M12 is 1.
75mm, M14 and M16 are 2.
0mm.
These are machine screws with a hex socket head – so you'll need an Allen key to drive 'em.
The left-hand rotation is key for applications where standard right-hand threads would loosen over time – things like certain machinery, woodworking jigs, or custom builds.
Available in single piece quantities or bulk packs.
Just pick your size and get the reverse-thread fasteners you need.
