Product Description

What are roofing bolts used for? 

Roofing bolts are actually made to be used in lots of different applications other than roofing. While they are ideal for joining metal to metal, they also work for other construction materials. Primarily we supply these bolts for fitting cable tray and trunking.
They are designed with a large flat head because the wide surface on that head allows the holding force to be spread further than a standard bolt. This means a more secure holding. Damage to the material is also reduced as the stress/tension spreads throughout the bolt.
Typically, roofing bolts are fully threaded which makes them even more suitable for diverse applications as they can join thin or thick materials, dependent on how far the bolt needs to be installed.

How to Use

As roofing bolts are versatile, it's obvious that they would be available in different sizes to suit different applications and fixtures.

The first number in a metric bolt size refers to the bolt's outer diameter. For example, a bolt specified as "M6 x 30" fits a 6mm diameter hole. The "M" indicates that it is a metric size.

The length of the rod follows in millimetres. The size of the nut will also be M (followed by a number) and this has to match up with the thread diameter in order to create the tightest seal.
