1/2-13 x 1/2 Cone Point Alloy Steel Socket Set Screw with Nylon Insert combines heat-treated alloy steel construction, internal hex drive access, and a nylon insert in one cone-point set screw. A spotted shaft gives the point a defined pocket, so the set screw can locate more positively during installation. Use this alloy steel body with the nylon locking pellet where the drawing calls for a mechanical set screw, not a corrosion-focused stainless part.
Pulley hubs and sheaves often use cone points when a prepared seat is available and the setting should not creep in service. Plain alloy steel is not selected for corrosion resistance, so keep parts oiled or choose a stainless request when the environment requires it.
Cold Headers installs nylon locking pellets in-house at its Chicago facility for this cone point set screw family. Cold Headers supports exact-size and hard-to-find cone point nylon-insert sourcing for industrial repair, replacement, and production requirements. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
