Thread in accordance with DIN standard 912 / ISO standard 4762. 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 series overview. 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) and A4 (316) (all according to DIN standard 912). Cylinder head screw with metric thread, 12.9. The RS Pro internal hexagon screws have a narrow head and are perfect for use in hard-to-reach areas, especially for the repair and maintenance of machines. Since this series is made from black, plain steel with high tensile strength of grade 12.9, it 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 applications, installations, and maintenance work.
