M4-0.7 x 6 mm Vacuum Vented Socket Head Cap Screws, M4 x 0.7 Thread Pitch x 6mm Long, 304 Stainless Steel, 1 Each. These M4-0.7 x 6 mm long vacuum vented socket head cap screws (SHCS) are drilled through the head and shaft to vent fluid and gases trapped below the screw, making them necessary for vacuum applications. These vented scews are sold by the piece (1 each). When used as vacuum fasteners inside a vacuum chamber, typical solid shaft (unvented) screws trap gases in the void space between the screw tip and the bottom of the threaded hole. These trapped gases are slowly released into the evacuated chamber thus creating what is known as a virtual leak. Virtual leaks slow down pumping processes and can significantly prolong the time needed to reach the desired base pressure. These vented screws, also known as vacuum screws, help eliminate virtual leaks from high vacuum (HV) and ultra-high (UHV) systems. Our vacuum compatible vented screw fasteners have been drilled through the entire length of their shaft allowing these trapped gases to vent out. These screws are non-magnetic and made of chemical and corrosion resistant 304 stainless steel. The screw length is measured from under the head (length of shaft only). We know that selecting the correct vacuum hardware for your vacuum system can seem like a challenging process. To make buying easier we sell the hardware individually by the bolt specifications (bolt diameter, thread type, and length), or in prepackaged hardware sets tailored for specific applications, such as for connecting ISO, CF (Conflat), or ASA flanges, or for connecting vacuum valves.
