Featuring a zinc-plated finish for corrosion resistance, these slotted round-head screws provide clean, flush seating in metal-to-metal connections. The 5/16-18 thread is common in many enclosures, panels, and equipment housings, making them a versatile choice for maintenance, assemblies, and repair work.

Applications

Ideal for electrical panels, control cabinets, automotive components, machinery assemblies, and other projects that require reliable slotted round-head machine screws.

Installation tips

Pair with a compatible nut or threaded hole and a driver suitable for slotted screws.
