Note: For the "W" assemblies, only the wing dimensions are shown. All other dimensions are the same as the Flush Head assemblies.

1258-F5xxx-Z3CT, 1258-F5Wxxx-Z3CT, 1258-F6xxx-Z3CT and 1258-F6Wxxx-Z3CT stud assemblies are sold with the stud and ejector spring secured in the mounting plate. The plate is riveted to the top of the removable panel, providing an advantage on weak materials by spreading stud tensile load. The extreme ejection on 1258-F5xxx-Z3CT, 1258-F5Wxxx-Z3CT, 1258-F6xxx-Z3CT and 1258-F6Wxxx-Z3CT studs is a special advantage on curved or sliding panels.

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.
