#8 x 1-5/8″ Drywall Screws Coarse Thread Black Phosphate

Drywall screws designed for fast fastening into drywall, wood and metal studs. Coarse thread type (UNC) with a flat head and sharp point that prevents damage during installation and eliminates the need for pre-drilling on most materials.

Specifications: #8 diameter, 0.32″ head diameter, 1-5/8″ overall length. Pack of 100 pieces. Black phosphate coated carbon steel construction. The black phosphate coating provides superior corrosion resistance and rust protection compared to uncoated fasteners, extending service life and maintaining structural integrity over time.

These screws perform reliably in residential and commercial applications including drywall installation, furniture assembly, and general woodworking. The flat head design sits flush with the surface, and the sharp point penetrates quickly without slipping during installation. Suitable for use on timber framing, plasterboard and engineered wood products.

The black phosphate coating offers protection in moderate moisture environments. For exterior or high-moisture applications, consider stainless steel alternatives.

Check the diameter and length suit your substrate thickness before ordering. Install using a power drill with an appropriate bit to avoid stripping.
