Professional Applications & Engineering Value
This M4 metric set screw delivers exceptional engineering value in applications requiring compact, reliable fastening solutions. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery, electrical enclosures, and automotive components exposed to moisture or chemicals. The vented design with 1.2mm diameter channel is particularly valuable in pressurized systems, precision instruments, and optical devices where air or fluid pressure equalization is critical. The headless configuration with hex drive enables flush mounting in tight spaces while maintaining secure torque transmission. The Class 6g thread fit and coarse thread pitch ensure rapid assembly and consistent clamping performance in high-vibration environments, making it ideal for production lines requiring both precision and efficiency.
Specification Summary & Compliance
This precision set screw features M4 x 0.7mm metric coarse threads with Class 6g tolerance for optimal fit in standard applications. The 4mm length with cup tip provides secure fastening in shallow engagements. Manufactured to industry standards with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and sensitive applications.
