Professional Applications & Engineering Value

This nylon patch locking set screw delivers exceptional engineering value in applications where vibration resistance and positional security are critical. The alloy steel construction with Rockwell C45 hardness provides the necessary strength for permanent fastening in machinery, automotive components, and precision equipment. The extended tip design ensures maximum contact with the shaft or component, preventing rotational movement while the Class 3A thread fit guarantees precise engagement in tight-tolerance assemblies. The permanent nylon patch thread locker eliminates the need for additional locking components, simplifying inventory and installation while maintaining reliability up to 250°F. This headless hex drive set screw is particularly valuable in space-constrained applications where flush mounting is required without compromising fastening integrity.

Specification Summary & Compliance

Manufactured to exacting standards with Class 3A external thread fit and 1/2"-20 UNF fine threads ensuring precision engagement. The extended tip features controlled dimensions with tip diameter of 0.344" and length of 0.13" with tight tolerances. This set screw complies with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring certified components.
