For those that prefer a black bolt we've got you covered.  These bolts are direct replacements for the US Standard measurement high quality stainless steel bolts that come with our control mount Biker Grippers.  Please make sure your model uses US standard measurements like most Harley-Davidsons.  Some models may require a metric application (we do not offer black metric bolts). Our Biker Gripper Perch/Control Mount kits include 2 stainless steel  (silver bolts). Please note we use silver stainless steel bolts due to the resistance to chipping and the resistance to moisture.  Black may chip over time just like the stock black torx bolts. These are replacements if you want black and measure 1/4"x 2"
