Collection: Specialist Bolts Purlin Bolts

Purlin Bolts Overview

Purlin bolt assemblies are commonly used in the fastening of roofing, framing, and wall sheeting across various industrial, commercial, and civil applications. Purlin bolts are a hexagon head flanged bolt with a matching flange nut, and come pre-assembled for added convenience. The flange design of the both the bolt and nut maximizes the grip and contact with the fastened components and maximises clamping load by distributing the force over a greater surface area, offering both higher performance and increased efficiency during installation. Made from both mild steel 4.6 grade steel and structural grade 8.8 steel, purlin bolts are available in bright zinc plate CR3+ and hot dip galvanised finishes. Each assembly comprises a flanged hexagon bolt coupled with a flanged hex nut.
