These are stainless steel - solid and well machined and milled - they are well finished - no burrs or markings and are secure - they are at home on leather and kevlar bands and installation is a 30 second maneuver with no tools. Most often people buy one and then get tired of switching to other bands so they buy more - I have these to fit the BUCKLE END of the band in 14, 16,18 and 20 mm please measure before ordering unless it is one of my bands.
