S-91390A159 M10 x 20 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance from the cup tip design, ensuring your assemblies stay securely locked in high-motion environments
• Exceptional strength and durability provided by the alloy steel construction and Rockwell C45 hardness, resisting wear and deformation under heavy loads
• Reliable and precise coarse thread fit (Class 5g6g) for faster installation and a secure hold in a wide range of materials
• Optimized for confined spaces with its headless and hex drive design, allowing for flush mounting and easy access with a standard 5 mm hex key
• Guaranteed interchangeability and quality through compliance with international DIN 916 and ISO 4029 standards
• Safe for use in regulated industries as it is fully compliant with RoHS 3 and REACH environmental directives
• Right-hand metric thread (M10x1.5) ensures compatibility with standard metric components, simplifying sourcing and assembly

Professional Applications & Engineering Value

This M10 set screw is engineered to solve critical fastening challenges in demanding industrial settings. Manufactured from high-strength alloy steel and heat-treated to a Rockwell C45 hardness, it provides the core strength needed to prevent loosening under constant vibration and shock loads, a common failure point in machinery and equipment. The headless design with a hex drive is ideal for applications where a protruding head is not feasible, allowing for a clean, flush finish in pulleys, gears, and collars. The coarse thread (1.5mm pitch) and specific Class 5g6g thread fit ensure rapid and deep engagement, reducing installation time while providing a robust connection that maintains its integrity, making it a vital component for assembly lines, automotive systems, and heavy-duty tooling.

Specification Summary & Compliance

This set screw conforms to the dimensional and tolerance requirements of DIN 916 / ISO 4029. The metric thread is M10x1.5 with a Class 5g6g fit, ensuring precision and interchangeability. It is manufactured to meet these specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
