This is a brand new stainless steel strain screw for Smith & Wesson K, L, and N frame square-butt revolvers that use the flat-leaf type mainspring. Measures .605" OAL and .480" under the head.  Fits models:  64 ,65, 66, 67, 610, 617, 624, 625, 629, 648, 657, 681, 686, and maybe more.

    Smith & Wesson stainless strain screw

    Fitted to a round butt S & W 625 that had a short strain screw. This cured the light primer strikes that occurred with hard Winchester primers.
