A Torx screw is recognized by its unique six-point star-shaped pattern, commonly referred to as a ‘star screw,’ requiring a ‘star screwdriver’ with a ‘star bit’ for tightening and loosening. This drive type, trademarked as star drive or six-lobe, is often abbreviated as TX or 6lobe, and its ISO name is hexalobular.
Vented screws are designed with a hollow core, featuring a drilled hole to enable the release of gases, contaminants, and pressure through the fastener. These Vented Screws play a crucial role in vacuum systems, enhancing the efficiency of pump-down processes for HV, UHV, and EUV systems.
