wide range of dimensions, quantities, materials, strength classes as well as surface coatings.
These screws are manufactured with right and left hand thread in both standard and fine pitch. We
use materials that we normally maintain in stock in strength classes 4.8, 5.8, 8.8, 10.9, 12.9 as well
as stainless steel. We can also use other specific materials upon request. Our ideal production volumes
range from tens to hundreds of pieces depending on the size of bolts. We can also provide surface
