We do not try to compete against the flood of imported Standard Petrochemical type Studbolts that are mass produced & cheaply imported. We excel in the Petrochemical grade bolting with larger diameters or where there is a pre-requisite of Non-Imported, Quality Assured UK Manufactured items. Hague Fasteners were one of the Original manufacturers of B7/2H Studbolt Assemblies in the 1970’s but excused themselves from the mass market as soon as the marketplace became flooded with inferior imports. To this day our excellence shines through with the High Temperature Material Grades and Super Duplex & Critical Stainless Steel Materials.
