Description

Frame Bolts Flange Black Phosphate 1/2-13 x 2 3/4 are precision-engineered fasteners designed for secure frame assemblies. Featuring a flange head and a 1/2-13 UNC thread, these bolts provide reliable, flush mounting in machinery, equipment, and structural frames. The 2 3/4 inch length offers versatile fit across a range of configurations, while the black phosphate finish adds a low-glare appearance and helps protect the fastener surface.

  • 1/2-13 UNC thread: compatibility with common frame hardware and tapped holes.
  • 2 3/4" length: suitable for medium-length fastening in frames and assemblies.
  • Black phosphate finish: durable, low-glare appearance with mild surface protection.

Ideal for frame construction, equipment mounting, and other structural assemblies requiring sturdy flange bolts. These fasteners are designed for reliable performance in industrial settings and are a dependable choice for professional-grade hardware projects.
