Midwest Fastener 5/16-18 x 3 in. Grade 8 Flange Bolt

The Midwest Fastener 5/16-18 x 3 in. Grade 8 Flange Bolt is engineered for high-stress fastening applications requiring exceptional strength and reliability. Manufactured from heat-treated Grade 8 steel and coated with a protective zinc finish, this bolt provides superior tensile strength and corrosion resistance in tough environments. Featuring an integrated circular flange beneath the hex head, this bolt acts as a built-in washer to distribute clamping force evenly across a broader surface area. This design helps prevent damage to mating surfaces and reduces the risk of loosening caused by vibration.
