S-96439A080 2-56 Press-Fit Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
• Reliable, permanent installation in thin panels as thin as 0.056" for secure fastening without welding or adhesives.
• Quick and precise assembly using a standard No. 19 drill bit (0.166" diameter), reducing installation time and errors.
• Consistent thread engagement with Class 2B thread fit and UNC coarse threads for easy starting and robust performance.
• Enhanced material compatibility and environmental safety with full RoHS 3 compliance.
• Optimized for high-volume production with press-fit design, enabling fast, tool-free installation in automated processes.

Professional Applications & Engineering Value

This 2-56 UNC press-fit nut is engineered to solve common challenges in electronics enclosures, communication devices, and lightweight chassis assembly. Its 18-8 stainless steel material offers excellent strength and corrosion resistance, preventing failure in humid or corrosive conditions. The round head and precise press-fit design ensure flush mounting without protrusions, while the coarse UNC threads provide rapid screw engagement and high resistance to vibration loosening. By specifying the exact panel thickness (0.056" min.) and drill bit size (No. 19), it eliminates guesswork and reduces assembly defects, making it a reliable choice for high-volume B2B manufacturing where durability and repeatability are critical.

Specification Summary & Compliance

This press-fit nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent fastener compatibility. Manufactured to precise dimensions: head height 0.07", head OD 0.25", and thread size 2-56. It is compliant with RoHS 3 (2015/863/EU) and designed for use in inch-system applications, ensuring reliable performance and regulatory adherence.
