S-91210A729 M8 x 60 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites deeply into materials, preventing component slippage and ensuring reliable positioning
• Exceptional durability and wear resistance thanks to the high-strength alloy steel construction and Rockwell C45 hardness rating
• Secure and efficient installation using a standard 4 mm hex key, providing high torque transfer in confined, headless designs
• Reliable coarse thread (M8 x 1.25mm) offers faster installation and superior performance in softer materials or where vibration is a concern
• Precision-engineered Class 5g6g thread fit ensures consistent, high-quality engagement for a secure and lasting fastening solution
• Full compliance with international standards including DIN 914 and ISO 4027, guaranteeing interchangeability and proven performance
• Safe for regulated industries with RoHS 3 and REACH compliance, ensuring environmental and safety standards are met

Professional Applications & Engineering Value

This M8 set screw is engineered to solve critical challenges in industrial assembly and precision engineering. Manufactured from high-strength alloy steel and heat-treated to a Rockwell C45 hardness, it resists shear forces and wear in demanding applications. The headless design with a hex drive allows for flush mounting in tight spaces, while the 90° cone point provides concentrated clamping force, preventing axial movement of components on shafts and hubs. Its coarse metric thread (1.25mm pitch) ensures rapid installation and maintains a strong grip, even in materials prone to stripping. This makes it an ideal choice for securing gears, pulleys, and collars in machinery, automotive, and automation systems, delivering reliable, long-term performance where maximum holding power is non-negotiable.

Specification Summary & Compliance

This metric set screw conforms to the precise dimensional requirements of DIN 914 and ISO 4027. The M8 x 1.25mm coarse thread is manufactured to a Class 5g6g thread fit, ensuring excellent dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial use.
