S-99051A230 M5 Press-Fit Nuts

Key Features & Benefits at a Glance

• Permanent, Vibration-Resistant Installation: Press-fit design ensures a secure, one-time installation that resists loosening under dynamic loads, eliminating the need for additional locking mechanisms.
• Superior Corrosion Resistance: Made from 18-8 stainless steel, this nut offers excellent resistance to rust and corrosion, ensuring long-term reliability in harsh industrial environments.
• Optimized for High-Volume Assembly: The round head and press-fit technology allow for rapid, tool-less installation into pre-drilled panels, significantly reducing assembly time and labor costs.
• Precision Thread Integrity: Features a Class 4H metric thread fit, providing consistent, high-quality engagement with mating screws for reliable, high-clamp force connections.
• Designed for Thin Metal Panels: Engineered for a minimum panel thickness of 1.38 mm, it provides a robust threaded solution in space-constrained and lightweight sheet metal applications.
• Guaranteed Material Compliance: As RoHS 3 compliant, this fastener meets stringent international environmental regulations, making it suitable for global electronics and machinery markets.
• Simplified Installation Process: Requires a standard 10.4 mm (0.4094 in) drill bit, streamlining the preparation process and ensuring a perfect, interference fit for maximum retention.

Professional Applications & Engineering Value

This M5 press-fit nut is engineered to solve critical challenges in metal panel fabrication and assembly. Its 18-8 stainless steel construction provides the necessary strength and corrosion resistance for demanding applications in electronics enclosures, telecommunications hardware, automotive control units, and industrial machinery. The press-fit (or interference fit) installation method permanently embeds the nut into the panel, creating durable threads without the need for welding, adhesives, or complex tooling. This eliminates the risk of thread stripping in thin materials and provides a reliable, high-strength point for component attachment. The coarse thread with a 0.8 mm pitch and right-hand direction ensures quick and easy screw engagement, making it ideal for high-volume production lines where speed, reliability, and a permanent threaded insert are paramount.
