Self Drilling Screw
Hi-Grips
Problem
Is there a better way to grip with roof fixing?
Solution
Hi-Grip, which is a secondary thread located at the top of the shank under the washer face. During installation, the washer face carries the fastener in downward motion while the Hi-Grip thread carries the roof profile in the upward motion. The upward pressure tends to straighten or reverse the indent made by the initial penetration and hence obstructing the possibility of water entry.
Advantages of High-Grips
- The operator may feel the thread bite, which is a clear signal to prevent over-drilling.
- Restricts “over-drilling” which leads to ponding or drimpling.
- Prevents sheet moving down the shank when roof is walked on.
- Grips sheet to provide “positive” joint with aluminium bonded EPDM washer.
- Extrudes metal around the fastener hole upwards making water ingress more difficult.
Shank Protection
Problem
There is a hidden danger of under-the-roof corrosion caused by scratching by the roof sheeting along the shank of the fasteners.
Solution
Shank Protection is a revolutionary patented design feature, to protect fastener shanks from scratching and scouring when crest fixing to metal roofing.
Advantages of High-Grips
- Cut a slightly larger hole in the roofing profile than the shank diameter, guarding and protecting it.
- Allow the fastener shank to remain unscuffed and scratch-free during installation, keeping the corrosion coating intact and fully functional.
