Product Comparison: “PS” vs. “SFSW”

The PAN-L-SCREWS listed on this web site and in our catalog are described with Head Type Code PS, replacing the SFSW code, which was listed in earlier catalogs. Both styles offer a captive assembly. The earlier SFSW style washer has the captive feature located on the bottom surface, while the PS style has this feature located inside the washer, leaving the bottom surface of the washer free of protrusion.

Drawing 9-45-0200-143 provides a comparison between the two styles.

Both styles are still available and are listed below with links to the product specifications.
