Specialty 6-, 12-, and 20-mm Posts and Post Holders

Specialty 6-, 12-, and 20-mm Posts and Post Holders

Our specialty post holders are the original optomechaincal components typically used in Japan.  These posts and post holders are in non-imperial sizes only: 6mm, 12mm, and 20mm.  They have the threaded stud machined into the post rather than it being a separate part.  The post holder is also a slightly different design than the current US or EU standard.  The material for these post holders either solid brass aluminum or stainless steel (vacuum compatible).  Additionally, the internal diameter on the brass post holders is not the typical double-bored type with the  kinematic "bumps". Rather, it is a single-bored high-tolerance slip-fit hole.  It's such a tight fit, air has difficulty escaping when the post in inserted in.  These products can be used on optical tables but keep in mind that the mounting thread is an M16x1 and the posts will not be compatible with the typical US or EU 12.7mm post diameter standard.
