Use and selection
The painted hex head is intended to coordinate with the roof sheet colour. Supply a colour reference or agreed sample alongside the roof-sheet and support details. Steel and timber are named support contexts; the required point, thread, screw length and washer configuration still need to match the actual fixing detail beneath the visible head.
Compare the configuration
Reduced Tip Roofing Screw is identified by its reduced drill point for light steel battens. Double Thread Roofing Screw identifies separate thread sections for sheet-and-support engagement. A colour match and a connection configuration are separate parts of the roofing specification.
For your enquiry
- What colour reference or approved sample should the head match?
- What roof-sheet profile, support material and thicknesses form the joint?
- What point, thread, length, finish and washer arrangement are specified?
