Common questions about hex flange bolts · din 6922
Can I order a flange bolt by diameter and length alone?
Those dimensions are not sufficient to define every flange-bolt design. Include the standard, head geometry, bearing-face form, material class and finish.
Can I request a size or material outside this listing?
Yes. Send the required dimensions and exact material grade for review. A quotation is needed to confirm feasibility, price and lead time.
