What is the difference between an S and SS part number and a CLS and CLSS part number. Why is there an additional S in the part number with the same thread size?
The original CLS and S (in the 10-32 and 10-24 thread sizes) were created for a smaller
(.234”) mounting hole. Due to many performance issues with these sizes, (because of the thin section between the thread and the undercut portion of the clinch profile) a beefier version was developed for a larger mounting hole. The original design (S and CLS) was eventually made obsolete and we're left with the SS and CLSS for these thread sizes.
