HiGrip® is a revolutionary design in roof fasteners that overcomes the traditional problems with crest fixing metal roofing to steel or timber.

HiGrip® - The Better Roof Fixing

Normal roofing screws often create an indent area around if the operator uses too much force while drilling.

HiGrip® is a secondary thread located at the top of the shank under the washer face. During installation the thread of the HiGrip® carries the roof profile in an upward motion; while the washer face is carried into the fastener in the downward motion.

  1. The operator feels the thread bite, a clear signal to prevent over-drilling.
  2. Restricts 'over-drilling' which leads to ponding or dimpling.
  3. Prevents sheet moving down shank when roof is walked on.
  4. Grips sheet to provide 'positive' joint with EPDM washer.
  5. Extrudes metal around the fastener hole upwards making water ingress more difficult.
  6. Unthreaded shank prevents profile riding up during fixing.
