Midwest Fasteners Zinc Plated Steel Indented Hex Head Self-Tapping Sheet Metal Screws

Midwest Fasteners Zinc Plated Steel Indented Hex Head Self-Tapping Sheet Metal Screws

Midwest Fasteners Zinc Plated Steel Indented Hex Head Self-Tapping Sheet Metal Screws are tapping screws built for drilling into sheet metal, thin gauge panels, and similar light-duty metal assemblies. This family is available in sizes ranging from #4 x 3/8" up to 3/8" x 1-1/4", giving fabricators and contractors a single source for a range of light-gauge metal fastening needs. Every size in the lineup shares the same steel construction with a zinc-plated finish for corrosion resistance, along with an indented hex head and hex drive connection that allows for fast, slip-resistant installation with a nut driver or socket — no stripped slots or cam-out like you get with Phillips or slotted heads. The silver finish matches most unpainted steel and galvanized surfaces for a clean, factory-style look on finished work.
