Description

Frame Bolts Flange Black Phosphate 5/8-11 x 4-1/4 are precision-engineered flange bolts designed for rugged frame assemblies. The black phosphate finish provides modest corrosion resistance and a low-reflection appearance for outdoor or mechanical environments.

Key features

  • Finish: Black phosphate coating for corrosion resistance and a low-gloss look.
  • Thread size: 5/8-11 for strong engagement and compatibility with standard frames.
  • Length: 4-1/4 inches overall length.
  • Flanged head: Built-in flange distributes load and reduces the need for a separate washer.
  • Application: Suited for frame assemblies, equipment mounting, and heavy-duty mechanical applications.

Applications

Use these frame bolts in automotive frames, machinery housings, and other equipment where secure, durable flange bolts are required. The 5/8-11 thread pitch ensures compatibility with standard nuts and threaded inserts commonly used in frame hardware.

Installation tips

For best results, pair with the appropriate nut or insert and, if specified by your equipment manufacturer, apply the recommended torque. Clean threads before installation and avoid overtightening to prevent damage to the bolt or the mating surface.

Add the Frame Bolts Flange Black Phosphate 5/8-11 x 4-1/4 to your cart today for reliable frame fastening that lasts in demanding environments.
