Key Features & Benefits at a Glance
- Exceptional holding power with high-strength alloy steel construction and Rockwell C45 hardness for reliable, long-term fastening in demanding applications.
- Precise and secure fit ensured by the Class 5g6g thread tolerance, minimizing the risk of loosening under vibration and dynamic loads.
- Simplified installation and removal with a 6mm internal hex drive, providing a flush, headless profile ideal for confined spaces.
- Optimized for rapid assembly featuring a coarse (2mm pitch) right-hand thread for quicker driving and reduced installation time.
- Enhanced grip and resistance to loosening due to the cup point tip design, which bites into the contact surface for a secure lock.
- Guaranteed dimensional and performance reliability through compliance with international standards DIN 916 and ISO 4029.
- Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This M14x2mm metric set screw is engineered to solve critical challenges in industrial assembly and machinery. Manufactured from alloy steel and heat-treated to a Rockwell C45 hardness, it provides the necessary strength to prevent stripping and withstand high shear forces. The headless design with a hex drive allows for a clean, unobtrusive finish in applications where protruding fastener heads are not feasible. The Class 5g6g thread fit and coarse pitch ensure a robust connection that is less susceptible to vibration-induced loosening, making it an ideal choice for securing gears, pulleys, and collars on shafts in automotive, manufacturing, and heavy equipment. The cup point tip offers superior biting action, creating a permanent setting that maintains alignment and torque integrity.
Specification Summary & Compliance
This set screw features a Metric M14x2mm coarse thread with a Class 5g6g thread fit, ensuring high precision and interchangeability. It is manufactured to the dimensional and mechanical specifications of DIN 916 and ISO 4029. 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 components.
