Torx 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 M8X1.25, these Stainless Steel flange bolts are great for solar applications
