Roofing Bolts & Nuts

Roofing Bolts are general-purpose fasteners featuring a large, flat (mushroom-style) head and a fully threaded shank. Designed to spread load over a wider surface area, they are ideal for fixing thin materials such as sheet metal, plastic and timber.

 
Supplied complete with a square nut, they offer a simple, cost-effective fastening solution for a wide range of construction and installation applications.

Product Description

Roofing Bolts are characterised by their wide, flat head - often referred to as a mushroom head - which allows the clamping force to be spread over a larger area compared to standard bolts. This makes them particularly suitable for thin materials, reducing the risk of pull-through or surface damage under load.

Typically fully threaded, these bolts provide flexibility across a range of fixing applications and are commonly used where a flush, low-profile finish is required. They are usually installed with a square nut, which can be easily tightened by hand or with standard tools, improving installation efficiency.

 
While commonly associated with roofing and guttering, Roofing Bolts are also widely used in racking systems, cable management, sheet metal assembly and general construction due to their versatility and ease of use.

 
Available in Bright Zinc Plated (BZP) for general indoor use and Hot Dip Galvanised (HDG) for enhanced corrosion resistance in external environments, they provide a dependable and economical fastening solution.

Applications

Ideal for roofing, guttering, sheet metal fixing, timber applications, cable trays, racking systems and general construction where a wide load-bearing surface and neat finish are required.
