Hillman Fasteners 48585 Star Drive Wood Screw 3.5in X10

Product Description

The HILLMAN FASTENERS 48585 is a 3.5 inches x #10 star drive all purpose wood screw designed for general construction, decking, and interior framing applications. It features a sharp point for fast starts, serrated threads that reduce drive torque, and a coarse thread pattern engineered for maximum holding power in wood and composite materials. The 6-point star drive system eliminates cam-out during installation. Four sharp countersinking blades allow the head to seat flush without pre-drilling a countersink. A knurled shank section below the head minimizes wood splitting. Licensed contractors, carpenters, and experienced tradespeople are the typical installers of this fastener.

This screw is suited for residential and light commercial wood construction, subflooring, sheathing, framing, and general wood-to-wood fastening. The combination of serrated threads and coarse pitch makes it effective in softwoods, hardwoods, and engineered lumber. Sold in a box of 12 screws, making it appropriate for job-site stocking. The sharp point and self-countersinking blades reduce the need for pilot holes in most standard wood applications.

Key Features

• 6-point star drive system eliminates cam-out during high-torque driving
• Serrated threads reduce drive torque for faster, easier installation
• 4 sharp countersinking blades seat the head flush without a separate countersink step
• Coarse thread pattern provides optimal holding power in wood substrates
• Knurled shank section below the head prevents wood splitting
• Sharp point for fast, clean starts without pre-drilling in most applications
• Lifetime guaranty from the manufacturer

Compatibility

Designed as an all-purpose wood screw for standard residential and light commercial wood-to-wood fastening applications where a #10 x 3.5-inch coarse-thread star drive screw is specified.

Installation Notes

Installation requires a T20 or T25 star drive bit, depending on the drive recess size of this screw size — verify the correct bit before driving. In dense hardwoods or near board edges, a pilot hole is recommended to avoid splitting despite the knurled anti-split feature. Use a variable-speed drill or impact driver at controlled torque to avoid overdriving and stripping the countersink. Always follow applicable building codes when fastening structural or load-bearing assemblies.
