Decoding Fastener Specifications: A Guide to Reading Technical Data Sheets

Keywords: Fasteners, Bolts, Nuts, High-Strength BoltsSelecting the right fastener goes beyond size. It requires understanding technical data sheets. For bolts and nuts, key specs include grade/class (e.g., Grade 8, Class 10.9), material (AISI 304 Stainless, ASTM A307), tensile strength, proof load, and hardness. High-strength bolts will have detailed requirements for heat treatment and mandatory mechanical testing. Learning to read these specs empowers engineers and purchasers to make informed decisions, ensuring compatibility, safety, and optimal performance in every application.
