S-91210A731 M8 x 70 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 under vibration and load.
• Exceptional durability and wear resistance thanks to the high-strength alloy steel construction hardened to Rockwell C45.
• Reliable and precise coarse threading (M8 x 1.25mm) ensures fast installation and a secure, deep-set fit in a wide range of applications.
• Secure internal wrenching with the 4 mm hex drive and headless design, allowing for a flush finish and access in confined spaces.
• Guanteed dimensional accuracy and interchangeability, manufactured to meet the stringent DIN 914 and ISO 4027 standards.
• Confident global sourcing with full compliance to RoHS 3 and REACH environmental regulations, ensuring safety and sustainability.
• Optimized for high-stress applications with a Class 5g6g thread fit, providing consistent clamping force and mechanical integrity.

Professional Applications & Engineering Value

This M8 set screw is engineered to solve critical challenges in machinery assembly, where components must be permanently secured against rotation and axial movement. The alloy steel construction and Rockwell C45 hardness provide the necessary strength to withstand high dynamic loads and fatigue. The 90° cone point design concentrates force on a small area, creating a powerful indentation that effectively locks pulleys, gears, and collars onto shafts. Its headless and hex drive profile is ideal for applications requiring a flush surface, preventing interference with moving parts. Manufactured to DIN 914 / ISO 4027 specifications, this metric set screw delivers reliable performance in demanding industrial environments, from heavy equipment to precision tools, ensuring long-term operational security.
