S-91390A167 M10 x 50 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with high-strength alloy steel construction and Rockwell C45 hardness for reliable, long-term fastening in demanding applications.
• Secure and flush installation thanks to the headless and hex drive design, ideal for applications where space is limited and a smooth surface is required.
• Superior resistance to loosening from vibration with the cup tip design that bites into the contact surface for enhanced locking capability.
• Precise and reliable fit ensured by the Class 5g6g thread tolerance, providing consistent performance and ease of assembly.
• Broad compatibility and interchangeability with components designed to the DIN 916 / ISO 4029 metric standard and coarse (M10x1.5) thread profile.
• Confident global sourcing with full compliance to RoHS 3 and REACH environmental regulations, ensuring safety and sustainability.
• Easy installation and removal using a standard 5mm hex key, streamlining maintenance and assembly processes.

Professional Applications & Engineering Value

This M10 set screw is engineered to solve critical challenges in precision assembly and machinery. Manufactured from alloy steel and heat-treated to a Rockwell C45 hardness, it provides the necessary strength to prevent stripping and withstand high shear forces. The headless and hex drive configuration allows for a completely flush mount, making it perfect for securing gears, pulleys, and collars on shafts without protruding components. The cup tip design offers superior bite, effectively resisting loosening under vibrational stress common in motors and rotating equipment. Adherence to the DIN 916 / ISO 4029 standard guarantees dimensional consistency and interchangeability, which is vital for maintenance and global supply chain efficiency in industrial and automotive applications.
