This 5/16"-18 x 3/4" serrated flange bolt is engineered for high-vibration applications where a secure, permanent hold is essential. The integrated flange acts as a built-in washer to distribute clamping pressure over a wider surface area, while the sharp under-head serrations bite into the mating material to resist loosening. Featuring a standard coarse thread and a durable finish, it provides a reliable, self-locking fastening solution without the need for additional lock washers.
