Professional Applications & Engineering Value

Engineered for thin panel applications starting from 0.056" thickness, this 18-8 stainless steel press-fit nut solves critical challenges in electronics enclosures, aerospace components, and industrial control panels where space and weight constraints are paramount. The UNF fine thread configuration (1/4"-28) provides enhanced thread engagement compared to coarse threads, significantly improving vibration resistance in high-stress environments. The press-fit round head design creates a permanent, torque-resistant connection without requiring welding or adhesives, eliminating potential failure points while maintaining corrosion resistance throughout the product lifecycle. This combination of precision threading, material durability, and simplified installation makes it ideal for applications demanding reliable performance with minimal maintenance.

Specification Summary & Compliance

This precision press-fit nut features 1/4"-28 UNF fine threads with Class 2B thread fit tolerance, ensuring consistent mating with standard UNF threaded components. Manufactured to precise dimensional specifications including 0.44" head OD and 0.17" head height for optimal panel engagement. Compliant with RoHS 3 (2015/863/EU) environmental standards and engineered for installation in panels prepared with standard 11/32" (0.3438") drill bits. The right-hand thread direction follows industry-standard fastening conventions for seamless integration into existing assembly processes.
