Machine Screws Slotted Truss Serrated Zinc Plated 1/4-20 X 1/2 are precision manufactured fasteners designed for secure, vibration-resistant metal-to-metal assemblies. With a 1/4-20 thread and a 1/2 inch length, these screws fit standard tapped holes and are ideal for electrical, cabinet, and hardware applications.

Key features:

• Slotted drive: compatible with standard flat-head or slotted screwdrivers for quick installation.
• Truss head design: low-profile head with a broad bearing surface to distribute load and prevent pull-through.
• Serrated under-head: helps resist loosening from vibration and dynamic loads.
• Zinc plated finish: provides corrosion resistance for indoor and moderate outdoor environments.
• Material: typically steel, ensuring strength and durability.

Applications include mounting electrical panels, assembling metal framing, mounting hardware in equipment enclosures, and other light to moderate-duty fastening tasks where a clean, flush finish is desired.
