Hammond SC616-50 M3 x 20mm Flat Head Self-Tap Screws, 50 Pack

The SC616-50 is a package of 50 M3 x 20mm flat head self-tapping screws. The Small Case Hardware list identifies them as assembly screws for the RM2 enclosure series, giving technicians and product builders a replacement option when the original self-tap screws go missing.

The long description reads "FH M3 x 20 SELF-TAP". As self-tapping screws they form their own thread when driven, unlike the machine-thread M3-0.5 x 20mm flat head screws in the SC610-50 pack that are also listed for RM2. Matching the thread type to the one originally used in your enclosure matters as much as matching the length.

Each package contains 50 screws. A 25mm self-tap version, the SC617-50, is also catalogued for RM2 and RL-DL enclosures. The SC616-50 is RoHS compliant and REACH compliant, with UPC 623980523958 and UNSPSC 39121301.

Enclosures in most cases include all hardware needed for assembly, so the SC616-50 is a replacement or spares item. Hardware packs may not be compatible with every part in a listed series, so check the series landing page or the "Replacement Parts and Accessories" section on your enclosure's part page before ordering.
