S-93187A116 M2.5 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from nickel-plated brass construction, ideal for humid or chemically exposed environments.
• Space-saving thin profile (1.6 mm height) enables use in compact assemblies where standard nuts won't fit.
• Reliable thread engagement with Class 6H thread fit ensures secure, vibration-resistant fastening in metric applications.
• Easy installation and removal with standard 5 mm external hex drive, compatible with common metric tools.
• Consistent performance guaranteed by compliance with DIN 439B and ISO 4035 international standards.
• Quick assembly efficiency with coarse 0.45 mm pitch right-hand threads for faster installation.
• Durable plating protection maintains appearance and function while resisting wear and galvanic corrosion.

Professional Applications & Engineering Value

This M2.5 thin hex nut solves critical space constraints in precision metric assembly while providing lasting corrosion protection. The nickel-plated brass material offers excellent conductivity and resistance to oxidation, making it ideal for electrical components, instrumentation, and marine applications where moisture exposure is a concern. Its DIN 439B thin profile allows installation in tight clearance areas of consumer electronics, automotive controls, and medical devices without compromising strength. The Class 6H thread fit and coarse pitch design ensure rapid installation with reduced cross-threading risk, improving production line efficiency while maintaining vibration resistance in dynamic operating environments.
