M3 ( 3mm ) High Tensile 10.9 Socket Countersunk Screws Black Self Colour Bolts

What are Self Colour High Tensile Screws?

Self Colour Screws are unplated screws that have a thermal Black oxide finish, these screws are usually coated with a thin layer of oil during production to prevent rusting during storage. These bolts are not suitable for outdoor use as they will easily rust due to having no protective plating applied.

 

These bolts are ideal for high stress applications or for where a high strength bolt is required due to the 10.9 high tensile strength. These are perfect for jobs where access is limited due to tightening by allen key or a hex wrench.
