S-93187A118 M4 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant nickel-plated brass construction ensures long-term reliability in humid or demanding environments
• Thin profile design (2.2 mm height) saves valuable space in compact assemblies while maintaining full thread engagement
• Class 6H thread fit precision guarantees secure, vibration-resistant fastening with consistent torque performance
• Coarse metric threading (M4 x 0.7 mm) enables quick installation and reduces cross-threading risks
• DIN 439B and ISO 4035 compliance provides guaranteed interchangeability and quality assurance for metric applications
• External hex drive style offers superior tool accessibility and torque transmission with standard wrenches
• Right-hand threading standardization ensures compatibility with common assembly procedures and components

Professional Applications & Engineering Value

This nickel-plated brass thin hex nut delivers critical performance advantages in applications where corrosion resistance and space constraints coexist. The M4 coarse thread configuration prevents galling during high-speed assembly while maintaining vibration resistance in automotive electronics, instrumentation panels, and electrical enclosures. The thin profile specifically addresses weight and clearance challenges in PCB mounting, control systems, and miniature mechanical assemblies where standard hex nuts would be prohibitive. The external hex drive ensures reliable torque application with common tools, reducing installation time and improving maintenance accessibility in confined spaces.
