Delta Fitt Inc is the leading stud bolts manufacturer in India, Choosing the right stud bolt is essential in industries like oil & gas, construction, power, and chemical processing. These threaded fasteners hold critical joints together, often in extreme pressure or temperature environments. When selecting stud bolts, understanding their materials, coatings, and standards is key to ensuring safety, durability, and performance.
This guide will help you make informed decisions when buying from a stud bolts manufacturer in India or a reliable stud bolts supplier in India. We’ll also highlight the importance of the HSFG Bolt Weight Chart and HSFG Nut Weight Chart for heavy-duty applications.
What Are Stud Bolts?
Stud bolts are long threaded rods with threads on both ends. They are used in flange connections and are secured using two heavy hex nuts. These fasteners are ideal for high-load and high-vibration environments due to their strength and stability.
Whether you're building pipelines, pressure vessels, or structural joints, stud bolts are widely trusted for their ability to maintain strong and leak-proof connections.
Common Materials Used in Stud Bolts
Choosing the right material is the foundation of selecting a suitable stud bolt. The material determines the bolt’s mechanical strength, corrosion resistance, and temperature tolerance.
Carbon Steel:
Used in general-purpose industrial applications where corrosion is not a major concern. Affordable and easy to source from any stud bolts manufacturer.
Stainless Steel:
Known for its corrosion resistance and strength. Grades like SS304 and SS316 are perfect for marine, food, and chemical industries.
Alloy Steel:
High tensile strength and excellent performance at elevated temperatures. Frequently used in oil & gas and power generation plants.
Duplex & Super Duplex Steel:
These offer exceptional corrosion resistance, making them ideal for offshore rigs and desalination plants.
A trusted stud bolts manufacturer in India offers all these material grades with quality assurance and third-party inspection certificates.
Protective Coatings for Stud Bolts
To improve the lifespan of stud bolts, manufacturers often apply protective coatings. The type of coating depends on the environmental conditions.
Zinc Plating:
Good for indoor applications or dry conditions. Provides basic corrosion resistance.
Hot-Dip Galvanizing:
A popular choice for outdoor use. It creates a thick protective layer that withstands rust and abrasion.
PTFE (Teflon) Coating:
Highly chemical-resistant. Used in acidic or highly corrosive environments.
Black Oxide:
Improves appearance and offers mild corrosion protection. Ideal for automotive or machinery parts.
Always check with your stud bolts supplier in India for coating options and compliance with your industry requirements.
Key Standards to Follow
When choosing stud bolts, compliance with international standards ensures performance and safety. These standards define mechanical strength, dimensions, and material properties.
ASTM A193 – Covers alloy and stainless steel stud bolts for high-temperature services.
ASME B16.5 – Standards for flanges and flange fasteners.
DIN & ISO – European and international norms for bolt sizes and threads.
Working with a certified stud bolts manufacturer guarantees full compliance with these standards, including test reports and traceability.
Importance of HSFG Bolt & Nut Weight Charts
For structural applications like bridges or high-rise buildings, High Strength Friction Grip(HSFG) bolts are used. These bolts are tightened to apply a clamping force that resists slip between connected components.
HSFG Bolt Weight Chart
Shows the weight of bolts based on size and length. This is essential for transport planning, inventory management, and structural load calculations.
HSFG Nut Weight Chart
Helps match nuts precisely with corresponding bolts, ensuring torque values are correct and performance is consistent.
Make sure to request the HSFG Bolt Weight Chart and HSFG Nut Weight Chart from your supplier for accurate engineering and procurement planning.
Why Buy from a Stud Bolts Manufacturer in India
India is known for producing high-quality industrial fasteners at competitive prices. A reputed stud bolts manufacturer in India offers:
Wide material range and custom specifications
Fast production and on-time delivery
Global standards (ASTM, ASME, DIN)
