Vented Stainless Steel Socket Head Bolts (Metric)

We recommend against using regular bolts inside a vacuum chamber because they leave small air pockets trapped under their threads. These pockets can take many months to pump down because of their small gas conductance.

Our vented socket head bolts have drilled holes which prevent gas pockets forming beneath the bolts. This results in quick pumpdown, eliminating the inconvenience of the annoying small gas leaks regular bolts cause.
