Professional Applications & Engineering Value

This 1/4-20 UNC press fit nut delivers critical engineering value by solving common panel mounting challenges in industrial equipment, telecommunications enclosures, and electronic chassis applications. The zinc-plated steel construction provides essential corrosion protection where environmental factors threaten fastener integrity, while the coarse thread design ensures reliable performance in high-vibration environments that typically cause fine-thread fasteners to loosen. The press-fit installation methodology eliminates the need for welding or adhesives, preserving material properties and reducing thermal stress on sensitive panel substrates. Engineered for 0.054" minimum thickness panels with precise 0.5156" drill size compatibility, this fastener delivers consistent installation results across production runs, making it ideal for automated assembly processes where repeatability is paramount.

Specification Summary & Compliance

This press-fit nut features 1/4"-20 UNC coarse threads with Class 2B thread fit tolerance for precision engagement with mating components. Manufactured to inch system specifications with right-hand thread direction, the fastener ensures compatibility with standard industrial components. The product maintains compliance with RoHS 3 (2015/863/EU) environmental standards, making it suitable for global distribution and use in regulated industries. Installation requires a 33/64" (0.5156") drill bit for proper press-fit application in panel thicknesses starting from 0.054".
