10-Pack Left-Hand Thread Hex Nuts – Metric Reverse Thread, 304 Stainless Steel, M4 To M20 Sizes Available, Hexagon Left Tooth Nuts

About This Product

Need reverse-thread nuts for a special project?

These left-hand thread hex nuts are made from 304 stainless steel, so they're strong, rust-resistant, and built to last.
Available in a bunch of metric sizes – M4, M5, M6, M8, M10, M12, M14, M16, M18, and M20 – so you can get exactly what you need.

Left-hand threads are essential when you're dealing with applications where standard right-hand nuts would loosen over time – think rotating assemblies, certain machinery, or custom builds.

These hex nuts thread on the opposite direction, giving you a secure lock that won't back off unexpectedly.

Solid construction, clean threads, and that classic stainless steel finish that resists corrosion.

This listing is for 10 pieces of your chosen size.

A must-have for any shop that does mechanical or metalworking repairs.
