An Introduction To Roofing Bolts & Spat Washers (Video)
In the video below, we discuss roofing bolts and spat washers; explaining how they are used and detailing the finish and sizes available.
What are Roofing Bolts & Spat Washers?
Roofing Bolts and Spat Washers are manufactured specifically for use within the roofing industry. However, they are handy fixings that can be used for other applications too.
What is a Roofing Bolt?
A Roofing Bolt is a fully threaded, mushroom headed bolt. They were traditionally used to affix corrugated roofing sheets to purlins on a roof structure; however, the versatility of the Roofing Bolt makes it an ideal choice for lots of different jobs. Roofing Bolts feature a slotted head, which means they can be tightened with either a flat head or cross head screwdriver.
Because of their large, flat head and fully threaded length, Roofing Bolts are most effective when used in conjunction with thin materials. The larger surface area of the head allows the holding force of a Roofing Bolt is stronger than a standard Bolt, meaning that the material it is affixed to is less likely to be damaged. Generally, Roofing Bolts are very secure, and can withstand strong weather conditions.
Our Roofing Bolts are supplied with a Square Nut for quick installation – however, they can also be used with any other type of nut with the same size. They feature a Bright Zinc Plated Steel finish and are available in M6 thread diameter. Our Roofing Bolt lengths range from 12mm to 80mm.
What is a Spat Washer?
Spat Washers are a type of Dowty Sealing Washer made of black plastic. They’re often used with Hook J bolts, but we recommend using them with Roofing Bolts too.
Like all washers, Spat Washers help to prevent damage to the material being fastened. They also provide a watertight seal between the fixing and material, which makes them ideal for roofing and other structures that will be exposed to extreme weather conditions.
Our Spat Washers are available in M8 diameter. They are made of nylon and feature a black finish.
