Grade A nuts are used with low carbon steel heavy hex bolts. Grade 5 are used with medium carbon cap screws and bolts. Grade C nuts are recommended to be used with A325 structural bolts. Grade 2H nuts are recommended for use in high pressure and high temperature service.
What is Grade C nuts?
What is the difference between Grade A and Grade B bolts?
What is a class 12 nut?

What is a Grade F nut?
F. This nut grade is for use with grade 5 bolts and usually denotes hex flange nuts.
What is a class 10 nut?
Class 10 nuts are metrics nuts with a steel grade equivalent to the SAE grade 8 classification. These are high-strength steels used in the automotive and structural industries.
What is Grade G nut?
An irregularly-shaped thread grips the bolt for a stronger hold than nylon-insert flange locknuts. They have a flange that distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Grade G locknuts are comparable in strength to Grade 8 bolts.
What is Grade A nut?

Will Grade 8 bolts rust?
Many other grades exist but are used far less often. Grade 2, 5, and 8 are usually plated with a slightly blue-ish or yellow zinc coating, or are galvanized, to resist corrosion. Bolts are typically marked on the head to show what grade bolt they are.
What is a grade G nut?
An irregularly-shaped thread grips the bolt for a stronger hold than nylon-insert flange locknuts. They have a flange that distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Grade G locknuts are comparable in strength to Grade 8 bolts.
How can you tell if a bolt is zinc plated?
Hot dip galvanising or zinc plating can be used on anything from small nuts and bolts to large beams for buildings. The steel is put in a big bath, where the coating is applied. If it’s galvanised, it will be dull grey and a little rough. A zinc plated product will be shiny and smooth.
What is yellow zinc used for?
