Machine Screws Unslotted Indented Hex Washer Zinc Plated 4/40 x 1/4 are high-precision fasteners designed for secure, flush seating in metal assemblies. Featuring an unslotted indented hex washer head, these screws distribute clamping force across the washer to resist loosening and provide a clean, low-profile appearance in panel mounting and equipment enclosures. The zinc-plated finish delivers corrosion resistance for reliable performance in indoor environments and light-duty outdoor applications.
Ideal for electronics enclosures, control panels, appliance assemblies, and other metal-to-metal connections, these 4/40 x 1/4 inch machine screws pair compatibility with standard 4/40 threaded holes and common hex-driver tooling.
