Metric Torx Socket Drive Serrated Flange Bolt, Stainless Steel
A Torx-40 wrench is used to install these screws, allowing access into 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. Serrated flange bolts are meant to permanently mar the material they are installed against.
A2-70 Stainless Steel is commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, agriculture, food processing, clean energy, etc.
These bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.
Also known as metric flanged torx socket head screw with serrations, ribbed flange bolt, flange bolt with integrated / built-in washer
