Double locking carcase screw Zinc diecast for precision Titus Double locking carcase screw makes an almost invisible connection Collar under the head to pull panels together 2nd ‘lower' thread pulls against a ‘faster' thread to provide maximum connection force and prevents overdriving of fastener Almost invisible in position Head can be ‘fastcapped' or filled Hi-Lo™ carcase construction screw The Hi-Lo™ carcase construction screw (CCS) offers a strong, tolerant and cost effective connection with minimal panel preparation. The combination effect of the elements of a Hi-Lo™ screw means • A greater differential between drive torque and strip torque in fibrous and particle materials to ensure a reliable and repeatable fixing • Hi-Lo™ threads provide minimum bursting forces • ‘Hi' thread gives low bursting component force from the sharp 30 degree angle thread • ‘Lo' thread at 60 degree angle uses the vertical force component to press fibrous and particle components of panels onto the ‘Hi' thread and are contained by their greater height • The very small shank on a Hi-Lo™ screw means less material displacement than conventional threads and enables minimum or partial drilling of pilot holes for quicker panel processing Barrel nut (plastic) • Used with Titus Hi-Lo™ screws • Titus barrel nuts provide maximum strip torque for reasonable drive torque • Capable of multiple reconnection repeatability Cover caps • Available in multiple colours • All recess and head types offered • High quality engineering polymers used in their construction • Uniformity of holding with good tolerance • Wide range of application and use conditions
