Crest Grip™ roofing screws are designed for crest fixing in roofing applications.͍A special thread section beneath the screw head grips tight to prevent movement and extrudes sheeting towards the washer for maximum water tight seal. This also prevents the sheet from moving when being walked on.͍These screws are assembled with a EPDM sealing washer and are completely compatible with zinc and COLOURBOND™ coated sheets.
