Bolts 101: Types, Grades, and How to Choose the Right One

Keywords: Bolts, High-Strength BoltsBolts are the heavy-duty connectors of the fastener world. A bolt is a threaded fastener designed to pass through holes in mating members and be secured by tightening a nut. They provide reliable, high-clamp-force joints ideal for structural applications. Not all bolts are created equal. They come in various types (hex, carriage, anchor) and are marked with grades (like SAE Grade 5 or metric 8.8/10.9) that indicate their strength. For critical applications in construction or machinery, high-strength bolts are essential as they are engineered to withstand extreme loads and prevent joint failure. Choosing the correct grade and type is paramount for safety and performance.
