Sheet Metal Screws – High Precision Fastening for Thin Gauge Materials
Product Description
Sheet Metal Screws are specially designed fasteners with sharp threads that cut through sheet metal, plastic, or other thin, rigid materials. Unlike machine screws, they don’t require pre-threaded holes—thanks to their self-tapping and self-piercing capabilities.
At SM Fasteners, we manufacture pan head, flat head, hex washer, and truss head sheet metal screws using high-quality case-hardened steel and stainless steel for superior thread cutting, rust resistance, and fastening strength. These are available with Phillips, Slotted, Torx, and Hex drive options.
Applications
Sheet metal screws are essential in industries where fastening thin-gauge materials is frequent and efficiency is critical:
HVAC Duct Installations
Electrical and Panel Fittings
Sheet Metal Fabrication
Automotive Trims and Interiors
Roofing, Cladding & Siding
Furniture & Modular Assemblies
Appliance Manufacturing
