Vented Socket Head Screws
Fully Threaded
Partially Threaded
Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications. Screws are 18-8 stainless steel; they have good chemical resistance and may be mildly magnetic. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

High-Vacuum Cleaned-and-Bagged Vented Socket Head Screws
Fasten these screws inside a high-vacuum system without bringing in contaminants. They are cleaned and double-bagged in an ISO Class 5 (Fed. Std. Class 100) clean room to eliminate impurities. A vent through the center allows fluids and gases to escape, which reduces the time it takes to reach vacuum conditions. These screws are 18-8 stainless steel, which emits less gas than most metals and stands up to corrosive chemicals. Length is measured from under the head.
