Question by: Dean W on Feb 23, 2026, 9:39 PM

Part number on my old screw is worn off and I can't make it out, supplier gave me C1DS64 as a cross. That the same thing as W1-14?

C1DS64 is a listed alternate part number for the W1-14, so yes, those reference the same fastener. When the original markings are gone, matching on either of those numbers gets you to the correct OEM Permco replacement.
