Color classification
304/316 stainless steel countersunk hex hollow screws are industrial-grade precision fasteners specialized for vacuum systems, exhaust pipelines, and perforated through-hole applications. Ranging from M2 to M16 metric sizes, they integrate a hollow perforated core, through-hole threading, and countersunk hex head—designed to deliver airtight performance, efficient exhaust flow, and flush-mount installation for sealed or precision industrial setups.
 
Made from high-quality 304 and 316 stainless steel, these screws offer graded corrosion resistance: 304 is ideal for general industrial, vacuum chamber, and dry exhaust environments, while 316 provides superior durability in humid, saline, or mild chemical conditions. The hollow perforated structure ensures unobstructed air circulation and vacuum pressure stability, while the full through-hole threading guarantees firm fixation without compromising system tightness. The countersunk hex head sits flush with surfaces, eliminating protrusions that could interfere with moving parts or seal integrity.
 
Engineered for anti-leakage and vibration resistance, they’re perfect for precision machinery, vacuum equipment, exhaust systems, and industrial sealing applications. The M2-M16 size range covers most standard assembly needs, ensuring seamless compatibility with existing fixtures and components.
