Product Description

The Hillman 90389 machine screw is a zinc‑plated steel fastener designed for strong, dependable metal‑to‑metal fastening in mechanical, construction, electrical, and general hardware applications. With a 1/4‑20 coarse machine thread and a 3/4‑inch length, it is ideal for short‑reach fastening tasks such as mounting brackets, attaching panels, securing components, and general assembly work.

This screw features a round head that distributes pressure evenly across surfaces and helps prevent material damage. Its combination slotted/Phillips drive design allows installers to use either a flat‑blade or Phillips screwdriver, offering greater flexibility in the field.

The zinc‑plated finish provides moderate corrosion resistance, making the screw well‑suited for indoor or outdoor use. Packaged in a 100‑count box, this SKU is an excellent choice for contractors, shops, facilities maintenance teams, inventory replenishment, or anyone performing repeated fastening operations.
