Manufacture of Critical Heavy-Duty Fasteners in all material grades, including 8.8, 10.9, 12.9, B7, B16, B8, B8M, L7 and Inconel 718
We specialize in manufacturing custom-engineered double-ended studs (stud bolts) and high-strength threaded rods to drawing for dynamic environments and extreme fatigue, temperature and corrosion conditions
Diameters from M20 to M100 and lengths of up to 8 metres (other diameters and lengths available on request)
Threads to ISO and ASME standards
In accordance with ISO 898-1 / ASTM A193 for stud bolts and ISO 898-2 / ASTM A194 for nuts
All types of surface coatings
Our products are manufactured from heat-treated, turned bars that have undergone eddy-current inspection at the steel mill. The bars are subsequently thread-rolled in a process that does not cut the steel grain flow, generating residual compressive stresses that improve the stud bolt’s fatigue resistance in environments with temperature fluctuations. Because the bars undergo eddy-current inspection, we guarantee the absence of inclusions, microcracks and surface defects
We apply the rigorous standards of our automotive IATF 16949 certification to the manufacture of stud bolts, using Lean production systems. This allows us to control our processes, ensure full traceability back to the steel mill’s raw material, achieve a zero-defect rate and offer express delivery times
