Professional Applications & Engineering Value
This 4-40 UNC press fit nut is engineered to address common challenges in sheet metal assemblies and electronic enclosures where space and weight are critical. The zinc-plated steel material offers excellent durability against oxidation and wear, while the press-fit design ensures a permanent, vibration-resistant installation without secondary operations. With its Class 2B thread fit and coarse thread spacing, it provides reliable performance in high-vibration environments, reducing maintenance needs. Compatible with a No. 19 drill bit (0.166" diameter), it streamlines panel preparation, making it ideal for automotive, aerospace, and telecommunications applications where precision and efficiency are paramount.
Specification Summary & Compliance
This press fit nut adheres to UNC thread standards with a Class 2B thread fit for consistent dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances. The nut is designed for a minimum panel thickness of 0.04" and requires a No. 19 drill bit (0.166" diameter) for installation, following industry-standard practices for press-fit nuts in inch-based systems.
