Identify the diamond pin
These diamond locating pins are the CL-123-DPT press-fit type. The source lists B shank diameter as 5/16 inch and nominal A diameter as 1/8 inch, with actual A specified as 0.1235 inch. Keep the diamond profile and exact part suffix in the replacement reference.
Dimensions to compare
The other recorded dimensions are C 1 3/16 inches, D 7/16 inch, E diameter 5/8 inch and F 3/32 inch. Read these letters against the source drawing before comparing a fixture. They should not be relabelled as overall height or mounting depth without checking the drawing.
A round pin with a similar nominal locating diameter is a different component. The profile and actual dimensions must match the locating arrangement in your design. This page does not establish fixture tolerances or a universal replacement relationship between round and diamond types.
The diamond profile in a locating arrangement
Diamond locating pins are relieved so that they locate in one direction. In a common two-hole arrangement, a round pin provides the primary location and a diamond pin supplies the remaining locating constraint. This arrangement allows for variation between hole positions that could otherwise cause two full round locators to bind. The orientation of the diamond profile is therefore part of the fixture design.
The relieved shape is functional. Check which direction the fixture drawing intends to locate before selecting a replacement. A picture showing a small metal pin does not capture that relationship, and a round pin with nearby dimensions serves a different role. Keep the profile designation with the part number when passing the requirement from engineering to purchasing.
Use the actual locating size
For CL-123-DPT, nominal 1/8 inch corresponds to the listed actual A dimension of 0.1235 inch. One eighth of an inch is 0.1250 inch, so rounding the actual figure to the nominal fraction would discard 0.0015 inch of the stated dimensional distinction. That comparison explains the two columns; it does not prescribe a mating-hole size or a permitted clearance.
The separate CL-124-RPT round pin has a listed actual A diameter of 0.1245 inch. Even though the nominal fraction is the same, the actual dimension and profile differ. Compare the exact reference assigned to each position in your fixture. Do not select both components merely because their nominal size labels match.
A component check before requesting availability
Review the locating profile, actual A dimension, B shank diameter and the remaining lettered dimensions as one specification. The shank attaches the component to the fixture, while the locating portion engages the relevant workpiece feature. Those two checks should remain distinct in your drawing review; the listed shank diameter is not a substitute for the locating dimension.
Count diamond locating pins separately from any round companion pins on the bill of materials. A request for two CL-123-DPT units represents two diamond components of the same reference. It does not instruct us to choose a locating arrangement or assemble a matched fixture kit. Keeping each reference separate makes the eventual availability and quantity confirmation clear.
Requested component and quantity
One proposed request unit is one CL-123-DPT pin. It does not include a round companion pin, fixture plate or bushing. The image is an illustration, not a scale drawing or a certificate of the pin's geometry.
Enter your name, email and requested quantity, then review the exact SKU before confirming. Availability, final price and delivery timing require separate confirmation before any purchase. This is an interest request only: no payment is collected and no order or fulfillment is authorized.
Questions about CL-123-DPT
- Are these diamond locating pins the round type?
- No. CL-123-DPT is the diamond, press-fit reference. A round locating pin is a separate product.
- What is the actual locating dimension?
- The source lists A as 0.1235 inch, alongside its nominal 1/8-inch description.
- Does the request include a matched pair of pins?
- No. One requested unit represents one CL-123-DPT component.
- Can I confirm fit using the image?
- No. Match the exact reference, profile and dimensioned drawing to the fixture design.
