Scope of delivery and selection

The price includes 500 high cap nuts M8 DIN 1587 zinc-plated. The catalogue mass of this exact full pack is 3,9 kg. The product and neutral carton graphics illustrate the family; the number of items in the picture does not specify delivery quantity.

The mating thread must be M8 with 1,25 mm pitch. Select the protruding screw length for the actual hole depth so the screw end does not bottom against the closure before the joint is properly clamped. Height h is not usable thread depth.
