Thorlabs' selection of thread adapters offers numerous options for switching between M2.5, M3, M4, M6, #4-40, #6-32, #8-32, and 1/4"-20 thread sizes. Choose from external-to-internal, external-to-external, or internal-to-internal thread adapters. We also offer internal-to-external threaded stud adapters.
The Mini-Series thread adapters can be used to make the Mini-Series posts compatible with our extensive range of optical mounts.
Threaded counterbore adapters are used to convert a counterbore to a threaded hole. A part such as the KM100 kinematic mirror mount features counterbores to provide imperial and metric compatibility. A caphead screw is typically used to fasten these mounts to a post, but in some instances it is necessary to attach the mount to a post with a fixed threaded stud. The counterbore adapter thus allows parts, such as the KM100, to be post mounted when a capscrew cannot be used.
The SD1 is an adapter ring that provides a means to attach #8-32 (M4) tapped components to 1/4"-20 (M6) counterbored parts. One possible use of the SD1 is in a dovetail optical rail setup where the RC1 rail carriers feature a 1/4" (M6) counterbore. Optic mounts are commonly attached to RC1 rail carriers and usually require the SD1 adapter as most optic mounts are #8-32 (M6) tapped.
