Box of 100 7.5 x 82mm Reisser Concrete Frame Screws.
REISSER CONCRETE FRAME SCREWS offer a versatile fixing solution for a variety of materials. Ideal for fixing window / door frames, timber battens, facades etc. into masonry. With a TXD (Torx) drive for maximum torque transfer and reduced “cam out” the CONCRETE FRAME SCREW gives a through fixing solution to prevent the need for marking and re-positioning. Locking ribs under the head fix firmly into the material and the flat pan head gives a neat finish when in place. The interlocking high low thread pattern gives very high pull out values, whilst the serrations on the threads removes more debris and reduces fixing stress, this also allows for closer fixing centres than expansion anchors and can be used closer to the edge of substrates. Manufactured from high grade steel for maximum durability and finished with a high quality Yellow Tropicalised coating to prevent corrosion CONCRETE FRAME SCREWS are available in a wide range of lengths to suit any application.
