Model # 77269102077 Store SKU # 1000739586

GRK's R4 self-countering screw has a new underhead with saw-blade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular saw blade, transporting the drill 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 treaent. This design also further enhances the R4 versatility by allowing the fastener to be installed without countersinking into even the hardest woods. The R4 screw closes the hole off with precision, leaving no damaged fibers around the head. Applications include wood, particle board, plastic, sheet metal, cement fiberboard, composite decking, wood decking and melamine.

  1. Recessed Star Drive: zero stripping, with 6 points of contact
  1. CEE Thread: enlarges hole to reduce splitting
  1. W-Cut: low torque, smoother drive
  1. Zip-Tip: no pre-drilling, faster penetration
  1. Cutting pockets: provide a clean hole, reduces splitting, and bore with precision
  1. ESR-3201 approved for structural application
  1. Case hardened steel: for high tensile, torque and shear strength
  1. Climatek Coating is AC257 code approved for use in treated lumber
  1. For interior/exterior use in wood, plastic, cement fibre board, particle board, sheet metal, wood decking and melamine

Can I use this screw for house framing?

Asked by: Geordie
Of course. GRK is a phenomenal product, however you need to be aware of local building code for lengths and screw # in order to frame anything properly. Act accordingly and this type of screw will be a good experience for you

How many screws in a package? The details claim each package contains just one screw, but this certainly is incorrect.
