This turnbuckle nut or adjusting nut is part of the Polar pull arm assembly (sometimes called a draw arm). It fits the newer models (EMC MON, EMC II, E, ED, X, and XT) of Polar 115 and Polar 137 paper cutters. After approximately 1984 the pull arms changed to using this style. These are all completely new, non-OEM, aftermarket parts. The overall length measures approximately 120mm (4-3/4") long, it has an outside hex size of 36mm, and it has both a LEFT Hand and a RIGHT Hand M24 internal thread.
It is machined complete from SAE 1045 steel. (equivalent to Polar 230046, 230046a, ZA3.230046, ZA3.258645a and 258645a)
