STAINLESS STEEL FULL THREADED STUDS – UNC & METRIC THREADED RODS | SS 304 & SS 316 STUD BOLTS
Conex Screws and Fasteners is a leading manufacturer and exporter of Stainless Steel Threaded Studs, supplying high-quality SS threaded rods, fully threaded stud bolts, and double-ended studs to clients across the USA, UK, Europe, Australia, and the Middle East. Our stainless steel threaded studs are precision-machined from premium-grade SS 304 and SS 316 stainless steel, offering outstanding corrosion resistance, mechanical strength, and dimensional accuracy for demanding industrial, marine, chemical, and construction applications.
What Are Stainless Steel Threaded Studs?
Stainless Steel Threaded Studs are fully or partially threaded fasteners made from corrosion-resistant stainless steel alloys. Unlike conventional bolts, studs do not have a head – they are threaded along all or part of their length and are designed to be inserted into tapped holes or used with nuts on both ends. They are widely used where a fixed anchor point is needed, such as in flanged joints, pressure vessels, automotive engines, pipelines, and structural assemblies.
Available in both Metric (ISO) threads and UNC (Unified National Coarse) threads, our stainless steel threaded studs meet international standards including DIN 975, DIN 976, ASTM A193, and ASME B18.31.
Stainless Steel Grades Available
- SS 304 Threaded Studs – General-purpose grade with excellent corrosion resistance; suitable for food processing, chemical plants, and architectural applications
- SS 316 Threaded Studs – Marine-grade stainless steel with superior resistance to chlorides and saltwater; ideal for offshore, marine, and pharmaceutical industries
- SS 316L Threaded Studs – Low-carbon variant of SS 316; used in high-temperature welding applications to prevent sensitisation
- SS 310 / SS 321 Threaded Studs – High-temperature grades; suitable for furnaces, heat exchangers, and elevated-temperature service

Types of Stainless Steel Threaded Studs We Manufacture
- Fully Threaded Studs (All-Thread Rods) – Threaded along the entire length; used where clamping force is needed across the full length or cut to size on-site
- Double-End Threaded Studs – Threaded on both ends with a plain or reduced shank in the middle; used for flange bolting and machinery assembly
- Tap-End Studs – One end with a short thread (for tapping into a fixed component) and the other end with a longer thread for the nut; used in engine assembly and pipe flanges
- Equal-End Studs – Both threaded ends of equal length; used in general structural and mechanical assemblies
- Weld Studs – Designed to be welded directly onto surfaces for a permanent threaded anchor point
