Note: The undercut length (.100"/2.54 mm) on this stud is insufficient for the self ejecting cup (.090"/2.29 mm) plus the panel and retainer. If this stud were installed with an ejecting spring and cup, the stud would pop out of the hole and have to be reassembled each time it is used. Therefore, the Self Ejecting (SE) configuration is not available for the Size 5 fixed undercut studs.

* is the "Stud Grip". For example, 1201-540-Z3CT is an oval head stud with a "Stud Grip" of 40.

Note: For all raised head styles, the "G" (Grip) and "U" (Undercut) dimensions are measured to the underside of the head. For the flush head style, the "G" (Grip) and "U" (Undercut) dimensions are measured to the top of the head.

Note: When our existing supply of Cadmium plated parts is exhausted, DFCI Solutions, Inc will no longer offer Cadmium plating as an option.

In place of the Cadmium plating, we recommend:

Clear: Zinc Trivalent Clear .0003 thick. Trivalent Chromate Clear with Sealer (RoHS Compliant)
Specification(s): ASTM-B-633, Type III, SC 2, Clear
Suffix: -Z3CT

Black: Zinc Trivalent Black .0003 thick. Trivalent Chromate Black Dye with Sealer (RoHS Compliant)
Specification(s): ASTM-B-633, Type II, SC 2, Black
Suffix: -Z3BT

Yellow: Zinc Trivalent Yellow .0003 thick, Trivalent Chromate Yellow Dye with Sealer

We recommend the Z3CT finish instead of the Z3YT finish. The Z3CT finish is much more cost effective and provides the same salt spray benefits as the Z3YT finish. (RoHS Compliant)
Specification(s): ASTM-B-633, Type II, SC 2, Yellow
Suffix: -Z3YT

The colored finishes offer no advantage over the clear other than the color, and they are more expensive.
