The Mansfield Faucet Handle 630-7975 comes with the handle screw. There will also be an installation guide on the back of the packaging. This handle is also offered in dark gray. Therefore, the handle is ready to install into the faucet. This handle fits Mansfield faucets model 300, 400, and 500. This handle fits some Duraflo faucets as well. Prier 300, 400, and 408 also use this handle. The handle screw is a self tapper, which means it will cut the threads as it goes into the end of the stem. The first time the handle screw is threaded in it may require a little bit of force to begin the threads.
