Description

Frame Bolts Flange Black Phosphate 7/16-14 x 3 1/2 are precision-engineered fasteners designed to secure frames and structural components with a built-in flange that distributes load for a cleaner, more reliable assembly. The black phosphate finish provides a durable, corrosion-resistant coating and a low-friction surface for smooth tightening.

Specifications

  • Thread size: 7/16-14
  • Length: 3 1/2 inches
  • Finish: Black phosphate
  • Type: Flange bolt

Benefits

  • Flange design helps seal and spread load, reducing the need for an external washer.
  • Black phosphate coating provides moderate corrosion resistance and aids lubrication during installation.
  • Suitable for automotive frames, machinery, and equipment assemblies requiring a robust 7/16-14 threaded bolt.

Applications

Use these frame bolts in framing, mounting, and structural connections where a 7/16-14 flange bolt of 3-1/2 inch length is appropriate. Confirm material compatibility and torque specifications for your project.
