Hex Head Set Screw - DIN 933

An “8.8 H/T Hex HD Set Screw Plain” is a strong, medium-tensile steel screw used in general industrial, construction, and automotive applications for general fastening and structural connections that need to handle shear and tensile loads. The “8.8” indicates a high-tensile, heat-treated steel grade, “H/T” means High Tensile, “Hex HD” specifies a hexagonal head, and “Plain” refers to the self-color or unplated finish. It is a fully threaded bolt, sometimes called a set bolt or set pin, and is often used with nuts and washers.
