Socket Head Cap Vented Screw
We vent our screws using a coaxial hole down the middle of the screw. Of the various methods used to vent screws for vacuum use, this one best preserves the fastener integrity.
Precision Cleaning
All catalog parts are shipped precision cleaned and Class 100 packaged. To reduce galling, use of a vacuum stabIe lubricant such as Molybdenum Disulfide (MoS2), Tungsten (WS2), graphite, or silver plating is recommended.
Coated and Plated Screws
A coated or plated screw has a lower friction coefficient than an uncoated one, resulting in a higher tension (or compression) value for a given torque.
Minimum Order Quantity = 25 pieces per size
