Proto Adapters come in several different forms and can help you to increase or decrease to the optimal drive-end size. Though they are not made to be used with power tools or to be over torqued, these adapters allow for convenient size adjustments for the job at hand. Whether you need a socket impact driver or any of Proto's other adapters, Tools Plus has you covered. Browse from our selection below and find the right Proto Adapter for your needs.
