Roofing Bolts

M5 x 8mm - Roofing Bolt with Nut - BZP - Pack of 25

Roofing bolts are commonly used to secure corrugated roofing sheets to the purlins on the roof structure. We offer two types:

Cross-slotted mushroom head with square nuts
Hook bolts with nuts

Our standard roofing bolts have a low profile, large round head often referred to as a mushroom head. Roofing bolts are supplied complete with a square nut. The head has a cross head for tightening/holding with a screwdriver.

Our hook bolts, which are most commonly used to fix roofing sheets into position, are available in a zinc and yellow finish. Each bolt is supplied with a square nut.
