Why choose brass machine screws?

Brass construction provides moderate strength with excellent corrosion resistance, ideal for indoor use and environments where a non-magnetic fastener is beneficial.

Flat, slotted design sits flush with panels and faces, creating a clean, low-profile appearance in electronics enclosures, cabinetry, and decorative fixtures.

4/40 thread size is a common choice for small hardware assemblies, offering reliable engagement in soft metals and plastics.
