Key Features & Benefits at a Glance

  • Superior holding power with Class 6g thread fit ensures precise, secure fastening in high-vibration environments.
  • Exceptional durability from alloy steel construction and Rockwell C22 hardness resists wear and deformation under heavy loads.
  • Efficient installation with a 17mm square head and external square drive provides high torque application without cam-out.
  • Reliable alignment and seating due to the extended tip design (4.3mm length) for positive location in assembly.
  • Broad industrial compatibility with coarse M16x2mm metric threads for quick assembly and common use.
  • Confident global sourcing as it is manufactured to DIN 479 standards and is RoHS 3 & REACH compliant.
  • Versatile 100mm length accommodates a wide range of material thicknesses in demanding applications.

Professional Applications & Engineering Value

This M16x2mm metric set screw is engineered to solve critical challenges in industrial machinery, automotive assemblies, and heavy-duty equipment. The alloy steel core provides the necessary high-strength to prevent loosening under dynamic loads and vibration, a common failure point in standard fasteners. The square head and external square drive style allow for the application of significant torque, making it ideal for set screw applications where a flush finish is not required but maximum clamping force is. The extended tip ensures positive engagement and seating, improving the reliability of the joint. Fully compliant with major environmental directives, this DIN 479 screw delivers trusted performance for OEMs and MRO professionals seeking durable metric fasteners.

Specification Summary & Compliance

This set screw features a Metric M16x2mm coarse thread with a Class 6g tolerance for a precise, consistent fit. The tip has a diameter of 12 mm (-0.27mm to 0 tolerance) and a length of 4.3 mm (-0.3mm to 0 tolerance). Manufacturing and quality are controlled to meet the DIN 479 specification. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it adheres to strict international regulations on hazardous substances.
