The BSL sign for "bolt" (noun) uses a G-hand sliding straight forward. This differs from "key" (noun), which uses a G-hand but performs a distinct twisting motion as if turning a key. It also differs from "lock" (noun), which often involves two S-hands or C-hands coming together or a single hand twisting, not a straight slide
