Professional Applications & Engineering Value

Engineered for demanding structural and machinery applications, these M27 hex head screws deliver critical performance where high tensile strength and corrosion resistance are paramount. The hot-dipped galvanized steel finish combats moisture, chemicals, and outdoor exposure, making them ideal for construction, heavy equipment, and infrastructure projects. With a partially threaded design and coarse metric thread (3 mm pitch), they provide superior clamping force and vibration resistance in steel frameworks, conveyor systems, and industrial machinery. The Class 10.9 rating and external hex drive ensure easy installation under high torque, reducing assembly time while maintaining joint integrity in dynamic load environments.

Specification Summary & Compliance

This heavy-duty hex head screw features precise Class 6g thread fit and metric coarse threading (M27 x 3 mm) per ISO standards, with dimensions including 110 mm length and 71 mm grip length. It conforms to DIN 6914/ISO 7412 manufacturing specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental safety and global compliance for industrial use.
