Extreme-Strength Steel Extra-Wide Hex Nuts—Grade 2H
Also known as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts and distribute the load over a large area. Grade 2H nuts are comparable in strength to Grade 9 bolts. They're about 20% stronger than high-strength steel nuts and are used in heavy machinery, such as earth-moving equipment.
Blue PTFE-coated steel nuts have a slippery surface to resist sticking during installation. They're resistant to chemicals and salt water.

High-Strength Steel Nylon-Insert Locknuts—Grade 8
A nylon insert grips the bolt to resist loosening without damaging threads. These nuts are reusable, but their holding power lessens with each use. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel locknuts.
Steel locknuts without a finish are ready to be painted or finished.
