304/316 stainless steel exhaust screws are precision-engineered industrial fasteners designed for vacuum systems, exhaust equipment, and airtight applications. Featuring a hex socket drive, round head, hollow structure, and punching vacuum through hole with full threading, these screws cover sizes 2.5-M12, delivering reliable airtight performance and durable fastening for mechanical systems.

Crafted from premium 304/316 stainless steel, they offer excellent rust and corrosion resistance—304 for general indoor/outdoor use, 316 for harsher marine, chemical, or high-humidity environments. The hex socket drive ensures secure tool engagement and precise torque control, enabling stable installation without slippage, even in narrow spaces of exhaust or vacuum equipment.

The hollow design with punching vacuum through hole facilitates air flow and pressure balance, while full threading ensures tight, airtight connections. The round head provides a smooth, low-profile finish, avoiding damage to surrounding components. Suitable for exhaust systems, vacuum pumps, air compressors, and mechanical equipment, these screws meet industrial standards for dimensional accuracy and long-lasting reliability.
