Bates T-Nuts for Sissy Bar Mounting Holes
Sometimes it's the little things in life that make the difference. Like this inconspicuous T-nut by Bates.
If you want to mount a sissy bar on Big Twin rigid frames 1936-1957, this is usually done at the mounting holes for the fender braces, which are located on the axle plates. The original mounting bolts are pushed through the axle plate from behind and secured from the front with a fairly large nut (wrench size: 5/8"). The problem is on the one hand, due to lack of space and mounting bolt length, the complete rear wheel as well as the brake base plate must be removed and on the other hand that the nut mounted from the outside leaves a rather bulky impression.
Bates T-nuts can be placed into the axle plate without removing the rear wheel and brake base plate. Additionally they are threaded, so the sissy bar can be mounted with a fairly plain 5/16“-24 screw. This gives the Harley-Davidson Chopper a much cleaner look. Two flats allow you to hold on to the T-nut with a 9/16“ open-end-wrench during installation.
