There are also tolerances in the angle and pitch of the gauge , and there are minute differences on the front and back.
When the effective diameter of the external thread to be judged is close to each other (just about large), the difference may not interfere with it.

It is a precision measuring tool and guarantees the product, so it is not used to remove welding.
In particular, care must be taken when inspecting aluminum because it is easy to weld.
OSG offers a threaded gauge with DLC coating that is effective when inspecting aluminum as standard stock.

If you want to convert the size and pitch of the unified thread standard to millimeters, please refer to the conversion table below.
You can check the number of UNC, UNF, and UNEF piles of unified threads, as well as UN standards.

BSF stands for F in BS (UK).
It corresponds to the fine line of W (thread angle 55°).
Please note that it cannot be shared with a unified thread angle of 60°.
Tap is available for special products.

Since it represents the number of mountains between 1 inch (= 25.4 mm), the pitch conversion (mm) can be calculated by dividing 25.4 by the number of mountains.
▽ Unified Screw Representation
Since the unit of measurement is inches, it needs to be converted to millimeters.
Calculated as 1 inch = 25.4 mm.
For 3/8-16 UNC,
・Outer diameter = 3/8
25.4×3/8＝9.525mm

There are two types of camera release screws: parallel screws and tapered screws. Both Tap (M3.4x0.5) are special.
gauge is also a special product, but the external thread is only a tapered screw, and the taper (slope angle of 14°) is too strong to produce a ring gauge .
