GRK FASTENERS 01141 10X4 R4 Star Drive FH 270/ProPak offers the perfect solution for both interior and exterior construction projects. This pack includes 270 screws designed for decking, stairs, and residential construction, making it an essential addition to any builder's toolkit. The R4™ self-countersinking screw features a patented underhead with saw-blade-like cutting teeth and six self-contained cutting pockets. This innovative design acts like a circular saw blade, effectively removing drill dust while creating a clean hole, even in the most brittle materials. It countersinks effortlessly into hard woods without damaging fibers around the head, ensuring a polished finish. With no pre-drilling required unless specified by the material, these screws streamline the installation process. The Starhead recess prevents stripping, adding to their reliability. Whether working with fibrous materials or tougher substrates, the extreme threads enhance grip and stability. For best results, use the red driver tip for #6 and #8 screws, and the green driver tip for #9 and #10 screws. With a length of 4 inches and a size of #10, these screws weigh 4.91 pounds and can be conveniently shipped via UPS. Elevate your woodworking and construction projects with GRK FASTENERS.
