S-91390A572 M12 x 80 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power thanks to high-strength alloy steel construction and Rockwell C45 hardness, ensuring reliable performance in demanding applications
• Precise and secure positioning with Class 5g6g thread fit, providing excellent dimensional accuracy and reducing the risk of loosening under vibration
• Easy installation and removal using a standard 6 mm hex key, facilitated by the headless design which saves space in compact assemblies
• Enhanced grip and resistance to slipping from the cup tip design, which bites into contact surfaces for a more secure fastening
• Broad compatibility and interchangeability with coarse (1.75mm pitch) M12 metric threads, conforming to DIN 916 and ISO 4029 standards
• Long-term durability and corrosion resistance in industrial environments, backed by the robust material properties of alloy steel
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives, ensuring no hazardous substances

Professional Applications & Engineering Value

This M12 alloy steel set screw is engineered to address critical challenges in industrial assembly, such as component slippage and misalignment. The headless design with hex drive allows for flush mounting in tight spaces, while the cup tip provides superior biting action on shafts and collars, preventing rotational movement. Manufactured from high-strength alloy steel and heat-treated to Rockwell C45 hardness, it withstands high shear and tensile stresses in heavy-duty applications like machinery, automotive systems, and precision equipment. The coarse thread (1.75mm pitch) ensures quick installation and robust holding in softer materials or where vibration is a concern. Complying with DIN 916 and ISO 4029, this metric set screw guarantees consistency and reliability, making it a trusted choice for engineers seeking durable, compliant fastening solutions.

Specification Summary & Compliance
