Flange Fasteners

Complete Your Flange Assembly

We supply a wide range of stud bolts for a variety of fittings. Ranging from zinc plated to stainless steel, we can provide stud bolts in a number of different sizes to suit your needs.

Our range of stud bolts covers the most commonly used specifications in the oil and gas, petrochemical, and power generation industries. We stock ASTM A193 Grade B7 carbon steel stud bolts with A194 Grade 2H nuts as standard, along with stainless steel options in A193 B8 (304SS) and B8M (316SS) grades. For high-temperature or corrosive service, we can source stud bolts in exotic alloys including Monel, Inconel, Duplex, and Super Duplex stainless steel.

Stud bolts are available in imperial and metric thread sizes, cut to standard or bespoke lengths. We can supply individual sets to match specific flange sizes or bulk quantities for shutdown and project requirements. All stud bolts are supplied with full material certification and traceability documentation as standard.
