Color classification
304/316 stainless steel hexagon punched hollow through hole screws are precision-engineered industrial fasteners, designed for exhaust systems, vacuum equipment, and applications requiring hollow through-hole threading. Covering metric sizes M3 to M12, these screws feature a hexagon head, punched hollow structure, and full through-hole threading, balancing durability, functionality, and compatibility with exhaust and vacuum systems where airflow or pressure regulation is critical.
 
Crafted from premium 304/316 stainless steel, they offer excellent corrosion, rust, and high-temperature resistance—316 grade provides enhanced protection in harsh, humid, or chemical environments, while 304 grade suits general industrial use. The hexagon head enables easy installation and secure torque control with standard wrenches, while the hollow through-hole design facilitates airflow, pressure relief, and seamless integration with exhaust pipelines and vacuum components. Precision-threaded construction ensures a tight, reliable fit for long-term performance.
