• Efficient installation and removal with the 8 mm hex drive, allowing for high torque application in confined, headless designs.
• Reliable and coarse thread engagement with M16x2mm right-hand threads, ensuring quick assembly and robust fastening in a wide range of materials.
• Precision thread fit meeting Class 5g6g, providing consistent performance and interchangeability in demanding applications.
• Global compliance and safety by meeting DIN 914/ISO 4027 standards and being RoHS 3 & REACH compliant for use in regulated industries.
• Versatile 20mm length offers optimal grip depth for a variety of industrial shaft-securing and positioning tasks.

Professional Applications & Engineering Value

This M16 set screw is engineered to solve critical challenges in power transmission and machinery assembly. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to resist shear forces and repeated adjustments without deforming. The 90° cone point is specifically designed to create a permanent, non-slip grip on shafts and collars, effectively preventing axial movement in high-vibration environments like motor pulleys and gear assemblies. The hex headless and right-hand coarse thread design allows for a flush installation, making it ideal for applications where space is limited and a secure, tamper-resistant fastening solution is paramount. Its compliance with DIN 914 ensures dimensional reliability for global engineering projects.

Specification Summary & Compliance

This metric set screw features an M16 thread size with a 2mm coarse pitch and a precision Class 5g6g thread fit as per ISO standards, guaranteeing excellent dimensional accuracy. The manufacturing and material specifications conform to DIN 914 (ISO 4027). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various industrial and export markets.
