Hillman Fasteners 48620 Stainless Exterior Screw 1.75in X 8

Product Description

The HILLMAN FASTENERS 48620 is a stainless steel exterior screw built for demanding outdoor fastening applications. Sized at 1.75 inches by number 8, it features a self-drilling point that eliminates the need for a pilot hole in most substrates. The star drive recess provides high torque transfer and reduces cam-out during installation. A knurled shank section beneath the head helps prevent wood splitting on entry. Rated for 2000-hour salt spray resistance, this screw is designed to hold up in coastal, high-humidity, and wet-exposure environments. It is sold in a box of 12 and carries a lifetime warranty from the manufacturer.

This screw is suited for residential and light commercial exterior construction and finish work. Typical applications include deck boards, fencing, trim, siding, and other outdoor wood assemblies where corrosion resistance is a code or performance requirement. The self-drilling tip makes it practical for production work where speed and consistency matter. Contractors, finish carpenters, and experienced DIYers working on exterior projects will find this fastener appropriate for pressure-treated lumber and exterior-grade composites.

Installation Notes

Installation is performed by carpenters, general contractors, or qualified tradespeople using a star drive bit. Verify the drive size matches the recess before applying torque to avoid stripping. When fastening into pressure-treated lumber, confirm the stainless grade is compatible with the preservative treatment used. Follow applicable building codes for fastener spacing and penetration depth on structural assemblies.
