304 S.S Plate Nut

Description:

The Plate nuts are metal plates with 2-threaded holes, shaped to match the corresponding CF flange's bolt hole patterns and replace the individual nuts. The plate nut’s major advantage is, once two bolts are manually started, the plate nut acts as its own backing wrench and washer—the bolts are tightened using one wrench. The plate nuts are perfect for those hard to reach(and see)spaces that are encountered during system assembly and service.  

Specification:

- Material : 304 S.S. 
- Size: CF16 ~ CF63

Applications for CF Components:

Assembly:

1.The CF flange connection consists of two identical flanges with a flat gasket made of OFHC copper, bolts, nuts. Because the applications are UHV environments, so the preparation work is very important before installation.

Surface cleaning guarantees the lowest possible outgassing and leak rates.

2.Using clean lint free gloves, place pre-cleaned OFHC copper gasket against knife edge seal, preferably the flange most likely to hold and support gasket from falling. With gasket in place fit mating flange with desired bolt orientation;

if flanges are fitted with leak test grooves, they should aligned.

3.With flanges aligned, insert proper size bolt and hand tighten. Repeat this procedure with remaining bolts. After hand tightening all bolts, support bolt and tighten nut using two closed end box wrenches. (washer are used on nut side) 

CF flanges are suited for use in applications requiring a very clean environment, ultrahigh vacuum conditions, high temperature or where critical or dangerous materials must be contained or excluded. This include:

Difficult applications with corrosive radioactive, toxic or air sensitive materials.

Materials creation and processing such as molecular beam epitaxial.

Analytical instrumentation including Auger electron spectrometers and electron microscopes.

High energy physics installations such as accelerators and fusion devices.
