Rods and Studs
South Coast Fasteners, Inc. is your trusted source for high-quality rods, studs, and everything in between. We stock a wide range of fastening products to support the needs of construction crews, industrial teams, fire protection systems, and mechanical builds. If it’s strength and stability you’re after, rods and studs are a staple that deliver every time.These parts might seem simple, but they’re workhorses. Rods and studs are used to anchor, support, and connect components across all kinds of applications. They hold strong under pressure and help keep everything locked in place.
Threaded rods are long bars with continuous threads from end to end, which makes them easy to work into a variety of fastening setups. You’ll often hear the terms “stud” and “threaded rod” used interchangeably, but it really comes down to size. If it’s under 12 inches, it’s typically called a stud. Anything 12 inches or longer is considered a threaded rod, also known as all-thread.

Types of Rods and Studs
Fully Threaded Studs
Fully threaded studs feature threads along their entire body length, offering maximum versatility in through-hole and anchor-style installations. These studs are commonly used in structural framing, industrial assembly, heavy equipment fabrication, and anywhere consistent engagement along the full length is needed for strength and adjustability.
Single-End Studs
Single-end studs are threaded on one end with a plain body. They’re ideal for use in tapped holes or embedded base plates where only one side needs to engage a nut or fastener. You’ll find them in automotive assemblies, heavy equipment, and mounting brackets where a flush end is required for clearance.
Double-End Studs
Double-end studs are threaded at both ends with an unthreaded center section, designed to connect two components with nuts on both sides. They’re a mainstay in engine block assemblies, gearbox frames, and structural plate anchoring where equal engagement and torque from both sides are needed.
Threaded Rod
Threaded rod is a continuous length of rod with unified threading, allowing nuts, couplings, or other threaded parts to be positioned anywhere along the body. Common in electrical, HVAC, fire suppression, and ceiling suspension systems, threaded rod is a flexible solution for fastening, bracing, or hanging mechanical and electrical hardware.
Unthreaded Rod
Unthreaded rods, sometimes referred to as dowel rods or plain rods, are fully smooth with no threads. Their high tensile strength and rigidity make them ideal for concrete reinforcement, lateral bracing, and structural support systems. These rods are frequently used in bridge work, seismic frames, and load-distributing anchors.
B7 Studs
B7 studs are made from heat-treated alloy steel designed to perform under extreme temperatures and pressures. They’re the go-to choice for petrochemical plants, boiler systems, refineries, and pressure vessels. These studs maintain structural integrity under thermal cycling, vibration, and corrosive exposure.
Industry Applications
Construction
Used to anchor beams, hang steel supports, and connect major structural assemblies. Studs and rods offer reliable performance in concrete embedments, curtain wall attachments, and seismic reinforcements.
HVAC
Threaded rods are frequently used to suspend air handlers, ductwork, and chilled water piping from overhead beams and support tracks.
Plumbing and Electrical
Support conduit, junction boxes, drain lines, and other equipment in residential and commercial systems using standard threaded rods and brackets.
Fire Suppression
Critical for fire sprinkler systems and seismic restraint of backflow devices and risers. B7 studs are often used for secure mounting of heavy fire-rated assemblies.
Heavy Machinery
Studs hold engine components together under pressure and vibration. Rods are used as axles, guides, or structural tie-ins between frame components.
Concrete and Structural Work
Unthreaded rods are embedded in concrete slabs and footings as tension reinforcements, tie-backs, or part of poured-in-place anchoring systems.
Material Options
South Coast Fasteners stocks rods and studs in a wide variety of materials tailored to both industrial strength and environmental exposure requirements.
Low Carbon Steel
Low carbon steel offers affordability and flexibility. It’s widely used in general-purpose applications where extreme strength or corrosion resistance is not essential. Its ease of welding and cutting makes it perfect for temporary bracing, light-duty anchoring, and in-shop assembly projects.
B7 Steel
B7 steel is a high-performance alloy material that is heat-treated for tensile strength and toughness. Its durability under heat and pressure makes it the standard for pressure vessels, structural piping, and petrochemical applications where failure is not an option.
Grade 5 Steel
Grade 5 is a medium carbon steel with heat treatment that increases strength and reliability. These rods and studs are commonly used in automotive components, machinery assembly, and agricultural equipment where strength matters without overengineering.
Grade 8 Steel
Grade 8 material is a high-alloy steel designed for ultimate load capacity. It is used in off-road suspension, crane construction, rail infrastructure, and any industrial fastening system requiring top-tier tensile strength and vibration resistance.
Stainless Steel 303, 304, 316
303 stainless is optimized for machinability, often used in custom fabrication. 304 stainless is the standard for corrosion resistance across commercial and industrial use. 316 stainless contains added molybdenum, making it ideal for coastal, marine, and chemical-exposure environments. All grades offer long service life in wet, corrosive, or sanitary applications.
Brass
Brass is non-sparking, corrosion-resistant, and easy to machine, making it ideal for electrical fittings, plumbing systems, and architectural hardware. It offers aesthetic value while maintaining solid mechanical performance.
Aluminum
Aluminum is valued for its lightweight, corrosion resistance, and ease of machining. It’s ideal for aerospace assemblies, cleanroom components, and non-magnetic equipment enclosures.
Copper
Copper rods are primarily used in electrical systems for grounding, conductivity, and bonding. They’re also used in HVAC installations for securing tubing and fittings that require corrosion resistance and electrical integrity.
Silicon Bronze
Silicon bronze combines strength with long-term corrosion resistance, making it a staple in marine, architectural, and grounding installations. The natural bronze finish adds both protection and aesthetic value for exposed hardware.
Available Finishes
South Coast Fasteners offers rods and studs in a selection of finishes engineered to protect, preserve, or customize each application.
Zinc Plated
Zinc plating provides a clean, silver-toned appearance and moderate corrosion resistance for indoor use. It’s commonly chosen for MEP systems, shop fabrication, and construction where aesthetics and clean threading matter.
Hot Dip Galvanized
This finish applies a thick zinc layer through immersion, offering robust corrosion resistance for outdoor and high-moisture environments. It’s the preferred finish for structural steel, bridge work, and external pipe hangers.
Plain
Plain rods and studs come without any plating or coating. This makes them ideal for welding, machining, or applying custom finishes as needed. They are often used in shops, testing labs, and jobsites where secondary treatment is expected.
