What are vented screws used for?
A vented screw features a hollow core (has a hole drilled through it) and are specially designed to allow the release of gases, contaminants, and pressure through the fastener. Vented Screws are widely used within vacuum systems and enable faster, more efficient pump-down of HV, UHV, and EUV systems.Jun 4, 2019
How does a cap screw work?
Cap screws have a large head and a cylindrical shaft with external threads. The head has a larger diameter than the threaded portion, this provides a positive mechanical stop when tightening the screw. Cap screws are tightened directly into a threaded or tapped hole, usually without a nut.Nov 18, 2014
When would you use a socket head cap screw?
1) Assembly Line Work - This hex shaped fastener can commonly be found used on assembly lines where the goal is to quickly and effectively apply fasteners. Socket head cap screws are particularly popular due to the fact that they can withstand applied force from their sides.Jan 15, 2019
What is the purpose of vented screw?
A vented screw features a hollow core (has a hole drilled through it) and are specially designed to allow the release of gases, contaminants, and pressure through the fastener.

Do socket head cap screws have grades?
Socket head cap screws are not grade designated as are hex head cap screws. A standard inch series socket head cap screw is 20% stronger than a Grade 8 hex head cap screw and 50% stronger than a Grade 5 hex cap screw.
