Use the 5/16-24 x 1 1/4 Brass Cup Point Socket Set Screw when the design calls for brass material, a cup point, and an internal hex drive. It has a 5/16-24 thread and 1 1/4 in. length for matching a drawing, parts list, or maintenance requirement. The cup point concentrates contact at the end of the screw to help position or retain the mating component. Brass provides corrosion resistance, electrical conductivity, and non-magnetic behavior in compatible equipment environments. The internal hex drive supports installation with standard socket tooling in compact assemblies. Common uses include medical equipment, small mechanisms, and precision fixtures, along with OEM machinery and industrial maintenance applications. Confirm thread engagement, mating material, and holding requirements before release to production. Call Cold Headers at 773-775-7900 or email your quote request to Sales@coldheaders.com.
