How do you classify fasteners?
Fasteners are identified by four or five attributes; Type, Material, Diameter, Length, and Thread Pitch or Count (machine thread fasteners only). This page describes what these attributes represent. Information on how they are written can be found on our How Fastener Measurements Are Notated page.

What are the grades of bolts?
A. The grade of a bolt indicates the tensile strength of the steel. The higher the number the harder it is. The most common grades are 2, 5 and 8. Grade 2 bolts are made out of mild steel and have no marks on the head, except maybe ‘A 307A’ . Grade 5 bolts are a medium hard bolt and have 3 lines on the head.
