A307 Grade B Hex Bolts

Click image to enlarge
Our ASTM A307 Grade B heavy hex bolts are manufactured from a high-quality medium carbon steel, providing a significantly stronger hold than grade A hex bolts. While these fasteners offer a similar tensile strength, their yield strength is almost double that of Grade A, making them ideal for more demanding connections. To complete a secure installation, be sure to pair your heavy hex bolts, A307 Grade B, with a compatible hex nut and flat washer
 
As a trusted supplier of industrial threaded fasteners, we offer a wide range of products, from standard hex bolts to specialized bolts for all your needs. These fasteners are available in finishes like plain finish, zinc-plated, and hot-dipped galvanized for superior corrosion resistance.
