Stereo Bolt Set

This set includes four bolts with knurled tops (one long--for the bottom right mounting hole of your lensboard--and three short).  The knurled tops are color-coded for particular bolt lengths.  The "Lens Info and Focus Scales" spreadsheet displays the length and color for every spacer combination.  This bolt set also includes a set of four washers, which can be used on any Mercury Stereo bolts.
