UHV and HV compatible Titanium and Molybdenum fixings

For research, prototyping, and precision mechanics in-vacuum fixings need to be from durable, heat-resistant material.

Allectra is pleased to offer Titanium (Ti) and Molybdenum (Mo) screws with relative washers and nuts suitable for high and ultra-high vacuum use, for instance for in-vacuum sample mounting, prototype assembly and fixing of critical parts..

Technical background:
A screw’s dimensions are defined with 3 numbers: the DIN (or ISO number) determines the shape; the M-number (M1.6, M2 etc.) determines the thread, and the last number gives the length in mm.
Though many other shapes and forms are available we consider these suitable for the majority of in-vacuum applications
