We are the premier UK distributor for UC Components, Inc.
We offer UC Components, Inc. washers that are the perfect complement to their vented and non-vented screws. The washers are made from the same high quality materials and available with the same specialty finishes that help the fasteners improve vacuum system performance. All washers are available in both metric and inch sizes.
These vented flat washers 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.
We also offer 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 metric and inch washer sizes with any standard finish.
All metric-measure vented and standard flat washers are manufactured to DIN and ISO standards. All inch-measure vented and standard flat washers are manufactured to meet NAS 620 and AN960 standards. Lock washers are manufactured to MS-35338 and DIN127B standards. All our washers are precision cleaned and packaged in a certified Class 100/ISO Class 5 Cleanroom environment.
