Flat Head Square Drive Spax ® Stainless Steel ('Double-Lock' Thread)

Referred to as the "multi-material construction screw", SPAX ® screws can be used in concrete, sheet metal, drywall, particle board, cement board, and even plastic materials. These patented screws have a square drive for excellent torque, and are available in 18-8 Stainless Steel for excellent corrosion resistance. No pre-drilling is required in most materials. The 4CUT point and serrated thread eliminates the need to pre-drill unless you are going into masonry or sheet metal greater than 24 gauge. The 'Double-Lock' Thread allows for exceptional pull-down and holding power. SPAX ® screws are an instant solution for almost any construction project.
