This sale is for two screws. These 3/8-24 threaded screws will fit the calipers on Harley-Davidson Big Twin & Sportster models 1978-2000. These will fit most all custom calipers also, please check your fitment for thread size. They use a 3/8" wrench, they are new, and they replace OEM part #44146-77. Thanks for looking, and be sure to check out my other items for sale. I gladly combine shipping when possible.
