S-91390A087 M1.6 x 3 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a cup point tip that bites into surfaces for secure, vibration-resistant fastening in demanding applications.
• Exceptional strength and durability from alloy steel construction and a Rockwell C45 hardness rating, ensuring long-term reliability under stress.
• Precise and reliable installation with a hex drive design, allowing for high torque application and reducing the risk of tool slippage or damage.
• Optimized for coarse threading (0.35mm pitch) and Class 5g6g thread fit, enabling quick assembly and robust performance in a wide range of materials.
• Space-saving headless design ideal for applications where a flush or low-profile finish is required without compromising on clamping force.
• Guaranteed dimensional consistency and interchangeability, manufactured to meet stringent DIN 916 and ISO 4029 standards.
• Safe for global use with full compliance to RoHS 3 and REACH environmental regulations, ensuring no hazardous substances are present.

Professional Applications & Engineering Value

This M1.6 metric set screw is engineered to address critical challenges in precision assembly, such as component slippage and loosening under dynamic loads. The alloy steel material, combined with Rockwell C45 hardness, provides excellent resistance to wear and deformation, making it ideal for high-stress environments. The cup point tip creates a permanent indentation for maximum grip on shafts and gears, preventing rotational movement in right-hand thread applications. Its hex drive and headless design allow for compact installations in machinery, automotive systems, and electronic devices where space is limited and reliable, vibration-resistant fastening is essential. Fully compliant with DIN 916/ISO 4029 standards, it ensures consistent performance and ease of sourcing for B2B procurement.

Specification Summary & Compliance

This set screw features a Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional accuracy and smooth assembly. It adheres to DIN 916 and ISO 4029 manufacturing specifications for reliability and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from restricted substances and safe for industrial use worldwide.
