Choose a hex head fastener with the right threading, thread size, material, and strength for your equipment.
Extreme-Strength Stainless Steel Flanged Hex Head Screws
Fully Threaded
Partially Threaded
For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength and can be used in heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.
450 stainless steel screws are more corrosion resistant than 18-8 stainless steel screws and have good resistance to chemicals and salt water. They are magnetic.
