About this item

Hillman 90383 #1/4‑20 × 1/2" Round Head Slotted Machine Screw – 100 Pack

The Hillman 90383 machine screw is a durable, zinc‑plated steel fastener designed for reliable metal‑to‑metal fastening in mechanical, construction, industrial, and general repair applications. Built with a 1/4‑20 coarse thread, this screw provides strong, secure engagement when driven into tapped holes or used with properly matched nuts.

The screw features a round head that distributes pressure evenly against the fastened surface, helping protect materials from damage during tightening. Its combination slotted/Phillips drive offers installation flexibility, allowing use with either a flat‑blade screwdriver or a Phillips driver.

At 1/2 inch in length, this fastener is ideal for shallow fastening tasks, equipment mounting, machinery assembly, electrical hardware installations, and any project requiring a short but sturdy machine screw. The zinc‑plated finish provides moderate corrosion protection, making it suitable for both indoor and outdoor use. Packaged in a 100‑count box, it is a dependable bulk choice for professional trades, maintenance teams, and dedicated DIY users.
