Socket: 1/2 in Drive Size, 13 mm Socket Size, Hand, 6-Point, Stainless Steel, Rust-Resistant

These stainless steel hand sockets have a 1/2" drive end for attaching to manual drive tools with a 1/2" drive size. They are typically used with stainless steel drive tools to install and remove stainless steel fasteners. Using stainless steel sockets and drive tools on stainless steel fasteners prevents contact (galvanic) corrosion that can cause rust.
