S-99051A120 M4 Press-Fit Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Exceptional panel retention with press-fit design that eliminates the need for welding or adhesives in panels as thin as 0.97mm
• Precision thread engagement with Class 4H thread fit for consistent, reliable fastening performance in metric applications
• Quick installation efficiency with right-hand coarse thread (0.7mm pitch) that speeds assembly while reducing cross-threading risks
• Optimized head design featuring 11.18mm round head that distributes load evenly and prevents rotation during press-fit installation
• Environmental compliance assurance with RoHS 3 (2015/863/EU) compliance for use in regulated electronics and industrial applications
• Perfect panel compatibility with precisely engineered 9.4mm drill size requirement for secure, vibration-resistant installations

Professional Applications & Engineering Value

This M4 press-fit nut delivers exceptional engineering value by solving critical panel fastening challenges in electronics enclosures, control panels, and thin-sheet metal assemblies. The 18-8 stainless steel construction provides superior corrosion resistance that withstands industrial atmospheres and chemical exposure, while the press-fit installation eliminates thermal distortion risks associated with welding. The Class 4H thread fit ensures precise engagement with mating components, preventing loosening under vibration - a common failure point in machinery and transportation equipment. With its 0.7mm coarse thread pitch and right-hand thread direction, this fastener enables rapid assembly in high-volume production environments while maintaining the structural integrity of thin panels starting at just 0.97mm thickness.

Specification Summary & Compliance

This precision metric press-fit nut features M4 x 0.7mm coarse threads with Class 4H thread fit per ISO standards, ensuring dimensional accuracy and reliable performance. The round head design measures 11.18mm OD with 3.31mm height, engineered for installation in 9.4mm drilled panels. Manufactured from 18-8 stainless steel with RoHS 3 (2015/863/EU) compliance, this fastener meets stringent environmental regulations while providing corrosion-resistant performance in industrial applications.
