Raptr thread cutting screws, available from Scrooz Pty Ltd are revolutionary fixings specifically designed to fix directly to masonry and concrete without the need for any form of expansion or a plug.
Raptr thread cutting screws can be installed quickly and simply by drilling a 6mm hole and then driving the anchor in using an electric screwdriver fitted with a TX30 driver bit. If necessary, the thread cutting screws can be installed by hand using a suitable socket drive and ratchet. All Raptr thread cutting screws are 7.5mm in diameter and available from 50mm to 200mm in length.
Raptr thread cutting screws feature a torx drive for a secure connection preventing 'cam out', a ribbed head for self countersinking in timber and a flat base for use with steel brackets and fittings.
Raptr thread cutting screws are designed and manufactured using a unique self cutting rifled threadform profile which cuts its own thread into the masonry and concrete.
Raptr thread cutting screws are a step forward in plugless technology and where normal expansion plugs grip only at the expanded end, Raptr's grip over their full circumference and their full length giving a large contact area in the masonry. This provides a simple high strength fireproof fixing that requires just a small drillhole. Raptr thread cutting screws have a bright zinc plate finish for corrosion protection.
These self tapping hardened steel anchors can be used in any masonry, stone or medium strength concrete. Raptr thread cutting screws provide a cost effective and fast alternative for the more traditional expansion type hollow wall anchors and are ideal for hollow concrete block and hollow bricks where expansion fixings won't hold. Raptr thread cutting screws work by biting firmly into the masonry and as they don't expand they are well suited for decorative concrete and stonework that may crack, particularly if close to an edge. Subject to site testing, Raptr thread cutting screws can also be used in some high strength concretes, sample packs are available.
Raptr thread cutting screws are ideal for fixing, window and door frames, screens and louvers, battens and timber sections, brackets and assemblies, tracks and channels, ducting and building services, rainwater pipes, electrical services and signage.
