S-93187A100 M3 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance due to high-quality brass material, ensuring long-term reliability in harsh environments
• Space-saving thin profile design allows for use in compact assemblies where standard nuts won't fit
• Precision Class 6H thread fit guarantees secure fastening and vibration resistance in demanding applications
• International standard compliance with DIN 439B and ISO 4035 ensures consistent quality and global interchangeability
• Easy installation and removal with standard external hex drive compatible with common metric tools
• Environmental regulation compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Reliable coarse thread engagement provides quick assembly and reduced cross-threading risk in production environments

Professional Applications & Engineering Value

This thin brass hex nut delivers exceptional value in applications where corrosion resistance and space constraints are critical engineering considerations. The M3 x 0.5mm coarse thread configuration combined with Class 6H thread fit ensures reliable performance in electrical enclosures, precision instruments, and marine equipment where vibration resistance and environmental durability are paramount. The thin hex nut profile (1.8mm height) solves clearance issues in compact assemblies while maintaining full DIN 439B and ISO 4035 specification compliance. Brass construction prevents galvanic corrosion when paired with compatible materials, making it ideal for plumbing systems, electronic housings, and automotive components requiring non-sparking, conductive fasteners.

Specification Summary & Compliance

This metric fastener features M3 thread size with 0.5mm coarse pitch and Class 6H thread fit per ISO standards, ensuring precise dimensional accuracy. Manufacturing complies with DIN 439B for thin hex nuts and ISO 4035 for metric hexagon nuts. The product meets RoHS 3 (2015/863/EU) compliance with exemption 6(c) for lead in copper alloy and is REACH (EC 1907/2006) compliant. External hex drive design provides 5.5mm across flats compatibility with standard metric tools.
