Professional Applications & Engineering Value
This M4 set screw with protective brass tip addresses critical challenges in precision assembly where surface protection and reliable fastening are paramount. The 18-8 stainless steel body provides exceptional corrosion resistance, while the soft brass tip creates a non-marring contact surface that prevents damage to shafts, gears, and other precision components. The hex headless design with 2mm drive allows for flush mounting in confined spaces, making it ideal for machinery, automotive, and electronics applications where space optimization is crucial. The coarse metric thread with Class 6g tolerance ensures rapid installation and secure holding power in vibration-prone environments, reducing maintenance requirements and improving overall assembly reliability.
Specification Summary & Compliance
This metric set screw features M4 x 0.7mm coarse threads with Class 6g thread fit per ISO standards, ensuring precise dimensional accuracy. Manufactured to ASME B18.3.6M specifications with a total length of 8mm and brass tip dimensions of 1.2mm length and 2.4mm diameter. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial fastener applications.
