Product Description

 

Product Description

DIN 938 - Double End Stud dimension

 

We manufacture stud bolts according to DIN938 standards  We are able to fulfil your requests for a
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
treatment, mostly galvanic or hot-dip galvanizing, but other treatements are available to meet
customer demands.

Notice: It is not always technologically feasible and appropriate to produce these screws utilizing our
manufacturing processes. Our sales department is available to consult any of your demands to meet your
specific needs.
