Standard studbolts are now widely available off the shelf in the more obvious ASTM grades such as B7, B7M, L7, L7M, B8 or B8M, but we continue to provide a unique manufacturing service of studbolts and ancillary products such as washers in the more exotic materials.

Recent projects have seen studbolts and threaded rod, complete with heavy hex nuts, to BS4882 or ANSI B16.5 and ANSI B18.2.2 or BS1769 respectively, being manufactured by us in the Duplex grade 254SMO (Also known under the specifications UNS S31254, 1.4547, X1 CrNiMoCuN 20-18-7 and F44).

Over the years we have produced studbolts and heavy hex nuts in a wide range of these Duplex and Super Duplex grades as well as in grades of Incoloy, Inconel, Hastelloy, Monel, Titanium and many other nickel-based critical alloys.

As we are not stockists of petrochemical grade studbolts and hex nuts we will not be able to compete with importers who buy their product in bulk quantities, but we are very competitive with any item that they do not have on their shelves or in their stock, particularly in these critical alloys and with rolled or screw-cut threads.

We can produce any type of studbolt:  threaded rod (DIN975 & DIN976), tie bar, waisted studbolts (DIN2510), engineer studs (DIN938) slotted studbolts & wheelstuds or to your specific drawings or sample pieces.  Please contact us for more details or view our sales brochure.
