5/16″ -18 x 3/4″ Conquest Grade 8 Indented Flange Bolt

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

The 5/16″ Conquest Grade 8 Indented Flange Bolt delivers strength and reliability where high tensile performance is required. Designed for precision, this bolt features a built-in indented flange head that distributes load and eliminates the need for separate washers, streamlining your assembly process.
