An assortment of stainless steel 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 #6-32 thru 1/2"-13 in USS coarse and SAE fine screw thread sizes and run 1/8" thru 1/2" in length. Full assortments of #3271 contain sixteen (16) refills comprised of Hillman item numbers #3272 - #3287.
