Product Information

Diamond Locating Pins (Press-Fit Type)

These precision locating pins are especially useful for workpiece location because of the wide selection of head diameters available to fit machined holes in the part. One Round Locating Pin and one Diamond Locating Pin are often used together to locate from two holes without binding, because the Diamond Locating Pin is relieved to locate in only 1 axis. The type shown here, with a press-fit shank, is designed for permanent installation. Head and shank diameters are concentric to within .0005" TIR. Made in USA.

Round & Diamond Locating Pins are available in four standard shank diameters, each with a range of standard head diameters in 1/32" increments (2mm increments in metric), each available in either standard or undersize fit. In addition to standard diameters, these pins are also quickly made to order in any special head diameter from .1150" to 1.0400" in .0001" increments. The Part Configurator link at the top of this page can be used for Diamond Locating Pins with a special head diameter.

Locating Principles

When a round pin and diamond pin are used together, the round pin is the primary, 2-axis locator, while the diamond pin is the secondary, 1-axis locator. Diamond pins are relieved to locate only radially around the round pin, avoiding redundant location. This prevents binding, yet still maintains high accuracy.

Specials

Pins with a special head diameter (A dimension) are quickly made to order in any of the four standard shank diameters.

5 5/16" shank

8 1/2" shank

12 3/4" shank

16 1" shank

Head diameters are limited to the following ranges:

5 .1150-.3180

8 .2780-.5040

12 .4640-.7540

16 .7140-1.0040

Example:

For a Diamond Locating Pin with a 1/2" shank and A = .4000", specify part number as CL-8-DPT-.4000.
