Bolt Depot - How to Identify Nuts, Bolts, and Screws

General. 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 Bolt Depot - Printable Fastener ToolsThe printable fastener tools series also includes general charts and tools for identifying and measuring fasteners, including a ruler and thread gauge. Note If you can't open these PDF files directly in your browser, you can use a PDF viewer, such as Adobe Reader (free).Bolt Grades What is It? What you should know about itThe nominal size of the grade 8 bolts can be from 1/4 to 1 1/2. The minimum yield strength of this grade bolt is 130,000 psi. A maximum of 120,000 psi of tensile force (proof load) can be applied to grade 8 bolts. Grade S Grade S bolts have the capability to withstand 45 to 49.9 MT of stress per 6.45 cm 3.

A metric bolt designated as ISO class 6.8 roughly corresponds in strength to an SAE Grade 2 bolt. Bolts of ISO class 8.8 and the slightly stronger class 9.8 roughly correspond to an SAE Grade 5 bolt. An ISO Class 10.9 bolt roughly corresponds to an SAE Grade 8 bolt.
