Allen Socket Drive Serrated Flange Bolts are an excellent choice for tight locations where a traditional external hex drive bolt would not fit. A flanged head design ensures superior force distribution over a greater area, eliminating the need for a separate washer.
The serrations on the bottom of the flange provide a locking action, digging into the parent material when tightened down.
Available in diameters M4 to M12, these Class 12.9 flange bolts are great for high strength applications.
