S-91390A090 M2 x 3 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with cup point design that bites into mating surfaces for permanent, vibration-resistant fastening
• Exceptional durability from Rockwell C45 hardened alloy steel that withstands heavy loads and repeated adjustments
• Precise thread engagement with Class 5g6g thread fit ensuring consistent performance and reduced assembly issues
• Optimized for industrial environments with coarse 0.4mm thread pitch that resists loosening under vibration and enables quick installation
• Space-saving headless design allows for flush mounting in confined spaces where protruding fasteners aren't feasible
• Global compliance assurance meeting both DIN 916 and ISO 4029 standards for international project specifications
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance for sustainable supply chain integration

Professional Applications & Engineering Value

This M2 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel construction with Rockwell C45 hardness provides the necessary strength to maintain clamping force in demanding applications like precision machinery, automotive assemblies, and electronic enclosures. The cup point tip creates permanent dimples in shaft components, preventing rotational slippage that compromises alignment in power transmission systems and precision instruments. Manufactured to DIN 916/ISO 4029 standards with Class 5g6g thread fit, these metric set screws ensure dimensional consistency across global production lines while the hex drive design allows for high-torque installation without stripping. The coarse thread spacing enhances resistance to vibrational loosening, making them ideal for industrial equipment subject to dynamic loads.

Specification Summary & Compliance

This precision set screw features M2 x 0.4mm coarse metric thread with Class 5g6g thread fit tolerance, 3mm length, and right-hand thread direction. Manufacturing complies with DIN 916 ISO 4029 specifications for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant (06/14/2023 235 SVHC), ensuring environmental regulatory adherence for global industrial applications.
