Replacement Jam Nut for Engine Slider Plate 3/8"-12 Screw Nut

The 3/8"-12 jam nut is the small piece of hardware that keeps your engine slider plate adjustment screw locked in place once you have your chain tension set. If you've stripped one, lost one in the pits, or just need a spare on the trailer, this is the exact replacement. Steel construction, standard hex profile, and the 3/8"-12 thread pitch that matches the adjustment screws used on common quarter midget slider plates including Zero Error and Ultimate QM.

Every engine change, every gear swap, every chain adjustment puts wear on this nut. Keep a couple in your toolbox so a rounded-off jam nut never ends your night at the track. This is an Ultimate QM part, sold individually, and in stock at Vast Quarter Midget Racing.
