Professional Applications & Engineering Value

These M4 metric screws with zinc-plated steel construction address critical industrial fastening challenges where corrosion resistance and mechanical strength are paramount. The coarse threading with Class 6g fit ensures rapid installation in production environments while maintaining vibration resistance in machinery, automotive components, and electrical enclosures. The rounded pan head design provides a low-profile finish that minimizes snagging while offering substantial bearing surface. With 60mm length and full threading, these fasteners deliver maximum engagement in thick materials and structural assemblies. The JIS drive system prevents cam-out issues common in high-torque applications, making them ideal for maintenance operations and OEM manufacturing where tool compatibility and reliability are essential.

Specification Summary & Compliance

Manufactured to precise metric dimensions with M4 x 0.7mm coarse thread and Class 6g tolerance per ISO standards. The 60mm length maintains tight tolerance of -0.15 to 0.15 mm for consistent performance. These screws conform to JIS B 1111 manufacturing specifications and meet RoHS 3 (2015/863/EU) environmental compliance requirements. Material hardness is certified at Rockwell B71, ensuring dimensional stability under load while maintaining the specified 60,000 psi tensile strength for reliable mechanical fastening.
