We manufacture vented flat washers to ensure that High Vacuum or Ultra High Vacuum systems have adequate ventilation under fastener heads in tapped holes for faster, more efficient pump-down of the system. Standard washer assembly may actually seal air underneath the screw head around the shoulder and/or threads of the screw.

UC also carries a wide variety of flat washers and split lock washers, as well as numerous other types and variations, such as internal and external tooth washers. All varieties are available in both inch and metric washer sizes with any of UC Components, Inc. standard finishes.
