Professional Applications & Engineering Value

This nylon insert locking thumb nut delivers critical engineering value by solving common industrial fastening challenges. The zinc alloy body provides excellent strength-to-weight ratio and corrosion resistance, ideal for outdoor or humid settings where metal degradation is a concern. Its wing-style head enables rapid hand-tightening, drastically reducing assembly time for maintenance covers, electrical enclosures, or adjustable components on machinery. The nylon insert acts as a resilient locking element, absorbing vibrations in motors, conveyors, or mobile equipment to prevent accidental loosening—a frequent cause of downtime. With UNC coarse threads and a 3/8" base diameter, it offers broad compatibility with standard inch-system bolts, making it a versatile choice for MRO and OEM applications requiring both speed and security.

Specification Summary & Compliance

This thumb nut features a 10-24 UNC coarse thread with Class 2B thread fit for consistent engagement and interchangeability. It is manufactured to applicable inch-system standards, including ASME B18.6.9 for wing nuts, and the zinc alloy construction complies with RoHS and REACH environmental directives. The locking mechanism utilizes a nylon insert rated for temperatures up to 225°F, ensuring reliable performance within specified thermal limits.
