5/8-11 x 1 1/2 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert combines the familiar socket head profile with a nylon insert for added loosening resistance. Nylon contact at the thread adds frictional resistance while preserving the standard internal hex drive arrangement.
This size is often reviewed for automation equipment, robotic end-of-arm tooling, and stainless brackets when a stainless cap screw must retain a familiar socket head form. 18-8 stainless is a practical choice for ordinary moisture exposure, washdown-adjacent machinery, and equipment where a clean stainless finish is specified.
For torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. For non-catalog pellet positions or unusual sizes, in-house pelletizing at the Chicago facility gives Cold Headers added sourcing flexibility.
