Product Description
The HILLMAN FASTENERS 48593 is a coarse-thread, star drive all purpose screw designed for general construction and wood fastening applications. Each screw measures 3.5 inches in length at a No. 10 diameter and features a sharp point for fast starts without pre-drilling. The 6-point star drive system eliminates cam-out, reducing stripped drives during installation. Serrated threads cut through material with less drive torque, and four sharp countersinking blades allow the head to seat flush without a separate countersink step. A knurled shank section reduces the risk of wood splitting near the fastener head.
These screws are suited for residential and light commercial wood framing, decking, sheathing, and general carpentry work. The coarse thread profile provides strong pull-through resistance in dimensional lumber, OSB, and similar wood-based substrates. Sold in a 5-pound box, this quantity is practical for production framing crews, finish carpenters, and remodeling contractors who need a reliable general-purpose fastener on hand in volume. The star drive requirement means a T25 or compatible bit is needed at the point of installation.
Key Features
- 6-point star drive system eliminates cam-out during high-torque driving
- Serrated threads reduce required drive torque for faster installation
- Sharp point starts without pre-drilling in most wood substrates
- 4 countersinking blades allow flush seating without a separate countersink step
- Coarse thread profile delivers strong holding power in wood and wood composites
- Knurled shank section minimizes splitting near fastener head
Compatibility
Designed as a general-purpose wood screw for use in dimensional lumber, OSB, plywood, and similar wood-based construction materials where a No. 10 coarse-thread fastener is specified.
Installation Notes
Installation requires a T25 star drive bit. Driving with an impact driver or drill at controlled speed reduces the risk of overdriving and splitting. In hardwoods or near board edges, pilot holes are recommended to prevent splitting even with the knurled shank feature. Follow applicable building codes for fastener schedules in structural applications.
