In heavy equipment where the screw is adjusted from the socket end, the 4-48 x 3/16 Cup Point Alloy Steel Socket Set Screw with Nylon Insert keeps the drive compact. The cup point is selected for localized holding contact; final selection still depends on shaft material, load, and access.

Packaging machinery and indexing assemblies can use the nylon insert where a cup point setting should hold through repeated cycling. Confirm thread size, length, hex key size, cup point geometry, pellet diameter, and pellet location before substituting another set screw.

Since 1962, Cold Headers has helped industrial buyers source specialty socket products for repair, replacement, and production needs.
