1/4-20 x 2 1/2 Cup Point Alloy Steel Socket Set Screw with Nylon Insert is the alloy version of a self-locking cup point set screw for machinery work. The cup point is selected for localized holding contact; final selection still depends on shaft material, load, and access.

Plant maintenance repairs often need the exact thread, length, cup point, and locking feature shown on the service record. 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.
