The Hillman 90425 machine screw is a long‑reach, zinc‑plated fastener designed for durable metal‑to‑metal fastening in construction, industrial, mechanical, and general hardware applications. With a 1/4‑20 coarse machine thread and an extended 4‑inch length, this screw is ideal for deep fastening situations such as mounting thick panels, securing brackets, connecting equipment housings, or fastening through multi‑layer assemblies.
The screw features a round head that distributes pressure evenly, helping protect work surfaces from damage during tightening. Its combination slotted/Phillips drive design offers compatibility with both flat‑blade and Phillips screwdrivers, making installation flexible across job sites and toolkits.
Constructed of steel with a zinc‑plated finish, the screw provides moderate corrosion resistance, suitable for indoor or outdoor use. Supplied in a 100‑count pack, this fastener is ideal for shops, contractors, maintenance teams, and inventory stocking programs requiring consistent performance for large‑scale or repeated installations.
