Hex Flange Bolt Serrated Full Thread UNC 3/8 x 2 1/2 inch in BZP Grade 5 - ASME B18.2.1 / SAE J429

Hexagon headed bolt with a flange. Also known as a washer bolt. The wider surface area beneath the head spreads the clamping pressure and negates the need for a washer. These UNC hex head flange bolts are serrated. The serrations are anti-rotational and bite into the material which they are connecting to secure the fixing.
