Product Description

[Applications]Jig positioning pin, medium class, set screw thread section short type.
[Features]Since the set screw thread section is short, it can be used for thin locators.
[ ! ] For Diamond Shapes, a step will be produced at the base of the P dimension.

Locating Pins for Fixtures, Standard Grade, Short Set Screw, Shouldered

Shouldered locating pins for jigs and fixtures with a short set screw section, so they can be used in thin locators. The polishing relief groove is smaller than on conventional products to avoid the workpiece getting caught.

Shapes: round and diamond. With the diamond shape, a machining step remains at the base of the P dimension.
Standard grade D tolerance h7, precision grade D tolerance g6. Standard grade concentricity is 0.03 or 0.05.
Unspecified dimensional tolerances conform to JIS B 0405 class m, except angular tolerances. Relief dimensions are reference values.

With the diamond shape, a machining step remains at the base of P.

Unspecified tolerances conform to JIS B 0405 class m, except angle tolerances.

Coaxiality of DLC-coated items is the value in ( ) (standard grade).

Tip shape. A center hole remains.
