For use in applications where a larger bearing surface is needed underneath the head. Used to fasten lath to wood. Type-17 point for fast starts. #2 Phillips drive.

Sharx ™ screws bite and hold fast in fiberglass, plywood and wood substitute materials. Use for projects exposed to harsh marine or many chemically caustic conditions. Ideal for applying trim, rub rail and molding to fiberglass boat hulls. Extra-sharp points speed screw starts during assembly. Specially engineered, high/low thread form incorporates indentations (“teeth”) that cut easily and quickly through high-density materials. Back-out resistance: once driven home, Sharx ™; are locked in place thanks to their “teeth” (the thread indentations will resist back-out even after prolonged vibration). Holding power: Pull-out values of Sharx ™; ;screws exceed those of ordinary tapping screws in fiberglass and wood. Screws up to 1" in length are fully threaded. Screws more than 1" long are threaded 2/3; of the shank length. Phillips drive.

Type-17 point for fast starts. Coarse threads approximately 2/3; up the shank draw board tightly to the substrate. Pre-drilling recommended near board ends to prevent splitting. Use with stable woods and wood substitutes when screw heads need to be hidden. #7 screw has 0.230" head diameter and #1 square drive recess. #9 x 3 1/2 " screw has 0.250" head diameter and #1 square drive recess. #9 x4" screw has 0.250" head diameter and #2 square drive recess. Choose type 316 for seaside applications and superior corrosion resistance.

Designed for installation in Simpson Strong-Tie ® structural connectors as well as wood-to-wood applications. Type-17 tip for fast starts, no pre-drilling required in most applications. Patented 4CUT™ 4-corner thread form greatly reduces driving torque. Double barrier coating provides corrosion resistance equivalent to hot-dip galvanization. Head is stamped with the Simpson Strong-Tie “No Equal” sign and fastener length for easy identification after installation. A low-speed 1/2 " drill with a 3/8 " hex driver is the recommended tool for installation. Code listed under ICC-ES ESR-2236.

For superior corrosion resistance in a range of applications including timber framing, pole barn construction, log homes, gutter installation and landscape timbers. Available in screw sizes 1/4 " and 3 ⁄ 8 " and lengths from 3 to 12 inches . 4-corner thread form significantly reduces driving torque. Drive with standard 5/16 " or 1/2 " hex nut drivers. Specify Timber Tamers ™ for outdoor construction projects requiring longer length screws.

These longer screws are ideal for fastening rain gutters to wood facia board. Sold in a kit of 12 screws, 12 aluminum ferrules and a hex driver. 3/16 Hex socket drive
