Brass Thumb Nuts

These brass thumb nuts make excellent replacements for buzz coils, spark plug nuts, and other electrical connections. When ordering nuts for spark plugs, be sure to check the number of threads per inch since some plugs use 32 threads/inch and others use 40 threads/inch. The easiest way to check is with a regular 8-32 nut. If it will thread on the plug, then it is 8-32. If it threads a little way on and then jamms, then it is 8-40. Sparkplug thumb nuts have a different profile than regular thumb nuts and are an excellent duplication of the originals.
