Our R4™ multi purpose screws is a self-countersunk screw with saw-blade styled cutting teeth and six self-centered cutting pockets that functions similar to a circular saw blade. The screws transports the dust away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment. The design also further enhances versatility by allowing the fastener to be installed without countersinking in even the hardest of woods. The screw head closes the the hole off with precision leaving no damaged fibers around the head.

Sizes 2" and longer have a special CEE thread that enlarges the screw hole for the non-threaded portion of the fastener allowing the wood to to settle easily thus increasing the screw's drawing strength and reducing the friction on the screw shank that lowers the driving torque. The Zip-Tip™ is desgned for fast starts in any fibrous materials.

Applications for our multi purpose screw includes wood, particle board, plastic, sheet metal, cement fiberboard, composite decking, wood decking and melamine.   

The screws are Climatek™ coated and have been independently tested and approved for use in treated wood products. No pre-drilling is required except where building material limitations are specified. Stainless steel screws are recommended for tropical wood, cedar wood, pool, sauna and deck applications in areas with lage daily temperature variances.
