Hillman Fasteners 48596 Star Drive Deck Screw 1.75in No.8

Product Description

The HILLMAN FASTENERS 48596 is a No. 8 x 1.75-inch star drive deck screw engineered for outdoor wood decking applications. It features serrated threads that reduce drive torque, a 6-point star drive system that eliminates cam-out, and four sharp countersinking blades that seat the head flush without pre-drilling. The coarse thread pattern delivers strong holding power in treated lumber and composite decking substrates. A knurled shank section reduces wood splitting near board edges. The 2000-hour corrosion-resistance rating makes this fastener suitable for exterior exposure. Deck installers and carpenters are the primary users of this screw.

This screw is intended for residential and light commercial deck construction and repair. It is well-suited for fastening deck boards to wood framing, including pressure-treated lumber. The sharp point starts without pre-drilling in most softwood and composite deck board applications. This SKU is packaged as a box quantity of 12 units, making it appropriate for stocking service trucks or job-site supplies.

Installation Notes

Installation is performed by carpenters, deck builders, or experienced DIYers using a star-drive bit matched to the 6-point drive system. No pre-drilling is required in most softwood applications, though pilot holes are recommended near board ends to prevent splitting. Confirm fastener corrosion rating meets local building code requirements for the specific treated-lumber preservative in use.
