The Flange bolt or screw is identifiable by the ridge of the bolt head. The bolt’s circular flange under the head acts as a non-rotating washer to distribute the load. Flange bolts are manufactured to provide the same holding power as a standard washer, and come in both serrated and non-serrated options. Browse our selection of hex head serrated flange screws, indented hex flange screws, and non-serrated hex flange screws.

Serrated & Non-Serrated Flange Heads
Fastener Solutions offers serrated and non-serrated heads on our flange head screws, with various coating material options.
Serrated Flange Heads
Serrated head flange screws have grooves cut into the head of the screw, providing advantages in certain contexts. Serrations provide resistance when used with gaskets, helping create an ultra-tight seal and reducing the likelihood of leakage. The teeth of the serrated head also help to bite into the surface of the mounting material, improving resistance to vibrations.
Non-Serrated Flange Heads
Non-serrated flange heads are smooth and do not “bite” into the mounting surface as the serrated heads do. Non-serrated flange heads are versatile, providing significant weight distribution and strength for various applications.
