The thread complies with DIN standard 912 and ISO standard 4762. It requires an internal hexagon key. We offer a wide range of internal hexagon screws made of plain steel, available in various thread sizes and lengths. Details can be found in the data sheet and the series overview, which can be downloaded as a file. If plain steel is not what you are looking for, we also offer internal hexagon head screws made of bright zinc-plated steel, titanium, and stainless steel A2 (304) as well as A4 (316), all in accordance with DIN standard 912. This hexagon socket screw has a metric thread of strength class 12.9. The RS Pro internal hexagon screws have a narrow head and are perfect for use in hard-to-reach areas, especially during the repair and maintenance of machines. This series of black, plain steel with high tensile strength of grade 12.9 is ideal when corrosion resistance is not required, but a firmer, more hardened material than grade 8.8 and 10.9 steel is needed.

Features and benefits: Can be used instead of hexagon screws with less play. Internal hexagon screw – the strongest of all head designs. The head height corresponds to the shaft diameter. Typical applications: Machine tool construction and repair, safety protection, household use, facilities, and maintenance work.
