These are 12.9 high tensile socket cap screws in a fine pitch thread, currently stocked in M10 x 1.25. Fine pitch means a finer thread than the standard coarse pitch (M10 x 1.5), which allows finer adjustment and is often specified on machinery, hydraulics and precision work. Like the rest of our 12.9 range they come self colour, built for strength rather than weather resistance. If you need a fine pitch size we do not list yet, give us a shout and we can usually source it.
