Hillman 90197 #8‑32 x 1‑1/2 in. Round Head Combination Machine Screw – 100 Pack

The Hillman 90197 machine screw is built for dependable fastening performance across a wide range of mechanical, industrial, and home improvement applications. Manufactured from strong, durable steel and finished with a protective zinc coating, this screw offers reliable corrosion resistance suitable for both indoor and outdoor environments. Its precisely cut #8‑32 machine threads run the full length of the shank, ensuring stable engagement whether you're fastening directly into a threaded receptacle or pairing it with a matching nut.

This model features a rounded head profile paired with a versatile combination drive, allowing installation with either a slotted or Phillips screwdriver. This dual‑drive design helps prevent over‑tightening, reduces wear on tools and materials, and gives users flexibility regardless of the tools they have available. The 1‑1/2 inch length—measured from beneath the head—makes it ideal for medium‑depth fastening tasks where consistent, secure thread engagement is essential.

Packaged in a practical 100‑count box, these machine screws are ideal for maintenance professionals, contractors, facilities teams, and DIY users who want a reliable stock of hardware ready for metal‑on‑metal fastening, equipment assembly, component repair, and structural hardware installation.
