The round locating reference
These round locating pins are the CL-124-RPT press-fit type. The listed shank diameter B is 5/16 inch. A is nominally 1/8 inch, with the actual diameter recorded as 0.1245 inch. Use the actual value when comparing the part reference with the specified locating geometry.
Check more than the nominal diameter
The drawing also lists C as 1 3/16 inches, D as 7/16 inch, E diameter as 5/8 inch and F as 3/32 inch. Keep those labels with the values until you have checked the drawing. Do not infer a fixture-hole tolerance solely from the pin's nominal size.
This is the round profile, not the diamond locating reference. Similar overall dimensions do not make the two profiles interchangeable in an existing design. The selected fixture arrangement and required fits need to be checked independently.
What the request includes
One proposed request unit is one CL-124-RPT pin. It does not include a fixture plate, installation service, companion pin or bushing. The illustration communicates general form and is not a dimensional inspection record.
What round locating pins do
Round locating pins provide a repeatable reference for positioning a workpiece or aligning fixture components. A round locating feature constrains movement in two directions in the locating plane. In a two-hole arrangement, a diamond companion pin can provide the remaining location while allowing for variation between hole positions. The complete fixture design determines which reference belongs at each position.
Locating and clamping are related checks within that design. The pin establishes the intended position; the surrounding workholding arrangement must provide the required restraint for the operation. This page identifies a replacement component and its published dimensions. It does not define a machining setup, specify a safe cutting load or supply the remainder of that workholding arrangement.
Compare the three dimensions that are easy to confuse
The 1/8-inch nominal locating size, 0.1245-inch actual A diameter and 5/16-inch B shank diameter describe different aspects of CL-124-RPT. Keep all three on the component comparison. The nominal fraction is useful for finding the product family; the actual diameter preserves the dimensional detail of this reference; the shank is a separate mounting feature.
One eighth of an inch equals 0.1250 inch. The listed actual locating diameter is therefore 0.0005 inch smaller than that nominal value. This arithmetic is a comparison of the published labels, not a recommended fit or manufacturing tolerance. The mating-hole requirement must come from the approved fixture drawing and the applicable component documentation.
Keep round and diamond references separate
The nearby CL-123-DPT diamond reference has an actual A dimension of 0.1235 inch. It shares the nominal 1/8-inch family description but has a different profile and actual locating dimension. The two references should remain separate line items, even when a fixture design calls for them together. This page records only the CL-124-RPT round component.
When checking an existing fixture, compare the part reference on the drawing with the intended locating position. Identify the shank mounting arrangement and the workpiece feature that meets the locating portion. If the original part number is missing, the photograph can help identify the general form, but it cannot establish the actual diameter, profile tolerance or installation fit.
Prepare an exact component request
For round locating pins, a useful quantity check starts with the bill of materials. Count the number of CL-124-RPT components specified per fixture and the number of fixtures being supplied. Two fixtures requiring one pin each would correspond to two units of this reference. Keep spares and different locating-pin types separately identified in your own parts list.
The request review shows the exact product and SKU with the quantity you entered. Check that line before confirmation so a nominal-size search does not become an unintended request for the wrong profile. The later availability response can then refer to the same component, while price, delivery timing and any purchase agreement are confirmed separately.
Availability request
Select the quantity and review the exact SKU alongside your name and email. Confirmation records interest only. Availability, final price and delivery timing will be confirmed before any purchase. No payment is collected, no charge is made and no order or fulfillment is authorized.
Questions about CL-124-RPT
- Which round locating pins are represented here?
- CL-124-RPT, the press-fit type with a 5/16-inch shank and nominal 1/8-inch locating diameter.
- Is the actual A diameter 0.1250 inch?
- No. The source records the actual A diameter as 0.1245 inch.
- Is a diamond pin included?
- No. A diamond pin is a separate component with its own exact reference.
- Does a request reserve this quantity?
- No. It records the quantity you want checked. Inventory and final supply terms remain unconfirmed.
