S-96439A640 M4 Press-Fit Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Secure, vibration-resistant installation through press-fit design that eliminates the need for additional locking mechanisms
• Precision thread engagement with Class 6H thread fit ensuring reliable, consistent fastening in metric assemblies
• Optimized for thin panels with a 2mm head height and 1mm minimum panel thickness requirement for space-constrained applications
• Simplified assembly process using a standard 5.4mm drill bit, reducing installation time and tooling costs
• Broad material compatibility due to RoHS 3 compliance, making it suitable for various regulated industries
• Right-hand coarse threading (0.7mm pitch) for quick installation and high resistance to loosening under dynamic loads

Professional Applications & Engineering Value

This M4 press-fit nut delivers exceptional engineering value by solving critical challenges in panel fastening and electronic enclosures. Manufactured from 18-8 stainless steel, it provides superior corrosion resistance where environmental factors threaten fastener integrity. The round head shape and precise 7.87mm OD ensure flush mounting without protrusions, while the Class 6H thread fit maintains consistent clamping force in metric coarse thread applications. Its press-fit technology eliminates threading operations in thin materials, preventing strip-out in panels as thin as 1mm – a common failure point in conventional nuts. This makes it indispensable for industrial fastening in telecommunications, automotive control units, and medical device assemblies where reliability and rapid installation are paramount.

Specification Summary & Compliance

This press-fit nut features M4 x 0.7mm metric coarse threads with Class 6H thread fit tolerance per ISO standards, ensuring precise engagement with mating components. The round head design measures 7.87mm OD with 2mm height, engineered for installation in 1mm minimum thickness panels using a 5.4mm drill bit. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) adherence, confirming suitability for electronics and regulated industrial applications requiring environmental safety standards.
