An assortment of class 45H metric socket set screw variants from The Hillman Group. Socket set screws are fully-threaded headless screws with a recessed hex drive. The screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. Included variants range M3-0.5 thru M5-0.8 in USS coarse screw thread size and run 4mm thru 12mm in length. Full assortments of #46056 contain sixteen (16) refills comprised of Hillman item numbers #1603 - #1611, #411098, and #411116 - #411121.
