Triton Alloys Inc selection of thread adapters offers numerous options for switching between 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.
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 cap 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 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 adovetail 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.
