Hex Flange Bolt Serrated Full Thread UNC 5/16 x 1-1/4 inch in A2 Stainless Steel - ASME B18.2.1

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.
