Request Information

For production equipment that needs a locking cup point, the 1/2-13 x 1 1/2 Cup Point Alloy Steel Socket Set Screw with Nylon Insert keeps the thread and length explicit. The internal hex drive keeps installation compact while the pellet adds resistance during installation and removal.

Mixer paddles and related shaft-mounted parts use cup point set screws where localized contact is acceptable. Confirm thread size, length, hex key size, cup point geometry, pellet diameter, and pellet location before substituting another set screw.

Cold Headers can help quote the requested cup point alloy size without substituting a different point geometry or head style. When a listed size is not the right fit, in-house pelletizing lets Cold Headers quote other set screw configurations.
