DIN 938 1Xd Stainless Steel Double Ended Threaded Bolt Specification 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.
