About this item

Hillman® XL-SDS Self-Drilling Screw – Model 41644 (#8-32 Thread, 1-1/4 in Hex Washer Head)

Product Overview

The Hillman® XL-SDS Self-Drilling Screw is engineered for fast, secure fastening in wood, fiberglass, and thin-gauge metal without the need for pre-drilled pilot holes. Featuring a self-drilling point and coarse threads, this screw creates its own hole and mating thread during installation, saving time and effort. Its hex washer head provides superior driving control and a clean finish, while the zinc-plated coating offers moderate corrosion resistance for indoor and light outdoor applications.

Perfect for general construction, HVAC, electrical, and metal-to-metal fastening, this screw is a versatile solution for professionals and DIY enthusiasts alike.
