Hillman Fasteners 48398 Deck Screws 1-5/8in X 8 5lb Box

Product Description

The HILLMAN FASTENERS 48398 is a 5-pound box of Deck Plus Green Ceramic exterior screws sized 1-5/8 inches by No. 8. These screws are designed for outdoor wood decking applications where moisture resistance and long-term holding power are the primary concerns. The green ceramic coating provides corrosion resistance rated at 1,500 hours of salt spray exposure, making them suitable for treated lumber and exposed exterior environments. The self-drilling cut point eliminates the need for pre-drilling in most softwood decking material. Drive type is star (Torx-style), which reduces cam-out during installation. This box contains a 5-pound quantity sold as part of a 4-package unit.

These screws are intended for use in residential and light commercial deck construction and wood framing applications involving pressure-treated or composite-adjacent lumber. The coarse, serrated thread pattern is designed to pull boards tight and resist backing out over time. Licensed contractors, deck builders, and experienced DIYers working on exterior structures will find these screws appropriate for treated wood substrates where ACQ or similar chemical treatments accelerate corrosion on standard fasteners.

Key Features

• Green ceramic coating rated for 1,500 hours of salt spray resistance
• Self-drilling cut point for faster installation without pre-drilling in softwood

Compatibility

Designed for use in exterior deck construction with pressure-treated lumber and standard softwood decking boards where a corrosion-resistant, coarse-thread exterior screw is required.

Installation Notes

Installation should be performed with a variable-speed drill or impact driver fitted with the appropriate star bit to match the drive recess. Follow deck framing guidelines per applicable local building codes for fastener spacing and edge distances. Wear appropriate eye protection when driving self-drilling fasteners. Do not use these screws as a structural shear fastener in applications requiring code-listed structural connectors.
