Screw taps for tripod thread & camera thread

Camera and C-Mount Thread

Photography is one of the areas in which imperial threads are commonly used in Europe. They are especially found on tripods and lenses, where standardized designs ensure safety when using often expensive equipment. Even though modern cameras typically use quick-release bayonet mounts, the classic lens thread is far from obsolete. The tripod thread also remains widely used. You’ll find all the tools you need to work with these threads in the BAER online shop.

Everything you need to know about the photo and C-Mount thread

When we speak of camera threads, we’re not referring to a single thread type but to several that have become standard across various camera models.

This includes the tripod thread, which comes in two sizes of American UNC threads: 1/4″–20 UNC and 3/8″–16 UNC. These are imperial threads with a 60° flank angle, outer diameters of 1/4 and 3/8 inch, and thread counts of 20 and 16 TPI, respectively. These threads ensure a secure connection between tripod and head, or between camera and mounting plate. A tight fit is crucial—not only for image stability but also to avoid damage to costly equipment. That’s why the robust UNC thread is favored here.

Lens threads include C-/CS-mount and S-mount types. C-mount lenses were once the standard in photography and film. This thread has a 1″ (2.54 cm) outer diameter and is imperial. S-mount is a metric thread (M 12 × 0.5) used for miniature or board lenses. Both are designed to securely mount interchangeable lenses to the camera body.
