U2 Fasteners - Universal Screw


A countersink fastener that allows the head to sit flush or below the surface of the surrounding materials. This ensures stability when other objects rest upon it. The countersink portion offers a good centering possibility.

Use: Decking, framing, sub-floors, fencing, lattice, shelfing, railings, stairs, fine wood working, lateral bracing, concrete forms and more.


  • Headtype: Countersunk head with burrow pockets to countersink in tough materials. 
  • Tight Star Recess system grasps the U-Bit tightly and can be installed with one hand.
  • Tapper Point consisting of the Cork Screw Start and Blade Cutting Thread for easy piercing and alleviating strain on material. Below the smooth shank is the Reamer Thread, which englarges the hole to create a passage when drawing materials together and reduces tension for the screw head.
  • Coating: It is hexavalent chromium (CR6+) free and complies with the strictest standards governing chemical substances. Prop 65 compliant U-Gold coating is compliant with Structural & ground contact ACQ treated lumber.
