Key Features & Benefits at a Glance

  • Superior holding power with a 90° cone point that bites into materials for maximum resistance against loosening under vibration and torque.
  • Exceptional strength and durability provided by alloy steel construction and Rockwell C45 hardness, ensuring reliable performance in demanding applications.
  • Precise and secure fit with Class 5g6g thread fit and coarse thread spacing, enabling faster installation and consistent clamping force.
  • Flush, space-saving design due to the headless and hex drive style, ideal for applications where a protruding head is not feasible.
  • Easy installation and removal using a standard 3 mm hex key, streamlining assembly and maintenance processes.
  • Guaranteed interchangeability and reliability as it meets DIN 914 and ISO 4027 standards, ensuring consistent quality and dimensions.
  • Safe for various industries with compliance to RoHS 3 and REACH regulations, making it suitable for environmentally conscious and regulated applications.

Professional Applications & Engineering Value

This M6 set screw is engineered to address critical challenges in industrial assemblies, such as component slippage and vibration-induced failure. The alloy steel material and Rockwell C45 hardness provide high tensile strength and wear resistance, making it ideal for securing gears, pulleys, and collars on shafts in machinery and automotive systems. The 90° cone point and coarse thread spacing ensure deep penetration and a firm grip, preventing rotational movement even under high dynamic loads. Its headless design and metric thread conforming to DIN 914/ISO 4027 standards offer a compact, reliable fastening solution for precision equipment, reducing maintenance needs and enhancing operational safety in B2B environments like manufacturing and automation.

Specification Summary & Compliance

This set screw features an M6 x 1 mm thread with Class 5g6g thread fit for precise dimensional accuracy, a 16 mm length, and a 3 mm hex drive. It complies with DIN 914 and ISO 4027 specifications for consistent performance and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial use.
