03 Apr.,2024

 

Description

Diamond pins are precision locating pins that have a chamfered tip for easy part loading, and a shoulder to resist downward forces. These locating pins have important advantages over standard dowel pins. One Round Pin and one Diamond Pin are often used together to locate from two mounting holes in a workpiece, or to align two pieces of a fixture, without binding. These stainless-steel diamond pins are relieved, to locate only in 1 axis. Head and shank diameters are concentric to within .0005″ TIR. Carr Lane Mfg. diamond pins are available with head diameters from 1/4 to 1″ (6 to 20mm in metric). Made in USA. ### Types of Diamond Pins Diamond Pins are available in three head-diameter tolerance ranges & press fittings: X = Normal Tight Fit Y = Medium Fit Z = Loose Fit

Diamond Pins

Precision locating pins that have a chamfered tip for easy part loading, and a shoulder to resist downward forces. These locating pins have important advantages over standard dowel pins.

Diamond Pin 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 while loading and unloading the part, yet still maintains high accuracy.
