Precision Shoulder Screws

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.

Mil. Spec. shoulder screws are designed to meet or exceed U.S. military specifications and standards to ensure high performance and reliability in extreme conditions. They are commonly used for defense-specific applications, aerospace, and in other highly demanding situations.

Self-Locking Standard Shoulder Screws

Self-Locking Standard Shoulder Screws
Self-locking shoulder screws resist unwanted rotation by using a thread-locking compound that is applied to the threaded part of the shank. This compound engages the threads on both components to prevent the screw from backing out or loosening due to vibration.

Self-Locking Precision Shoulder Screws

Self-Locking Precision Shoulder Screws

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.
