This Ø1 in stainless steel mounting post is used in applications where rigidity and stability are most critical. Mounting critical components on these fixed height nonØmagnetic, stainless steel posts overØ1/2 in posts can provide a more stable starting point for an optical setup. This post is tapped with a 1/4-20 at one end to mount directly to the optical table or base and an #8-32 on the other end to directly mount component holders like mirror mounts and fixed optic mounts. The post also has a Ø1/4 in hole through the middle to allow a ball driver or L-wrench to be inserted providing extra leverage when tightening or loosening the post. A relief cut has been provided on both ends to ensure proper seating.
