Precision shoulder screws are manufactured with more exacting tolerances than standard shoulder screws. This makes them ideal for applications requiring high degrees of precision such as laboratory equipment, certification equipment, and measuring devices.

Self-locking precision shoulder screws combine the strict tolerances of precision screws and the ability to resist unwanted rotation due to vibration. They feature a thread-locking compound applied to the screw threads which engages both components and helps prevent the screw from backing out or loosening due to vibration.
