Alloy Steel Thread Stud Bolts DIN 976
Thread stud bolts are essential components in heavy-duty assembly applications across numerous industries. Known for their high tensile strength and superior performance, these fasteners are widely used where secure, durable fastening is critical. Flybear Fastener offers precision-manufactured thread stud bolts that meet the DIN 976 standard, crafted from premium-grade alloy steel for superior strength and reliability.
Product Overview
Thread stud bolts are externally threaded rods with no heads, commonly used in industries such as automotive, construction, energy, and manufacturing. They are designed to be used with nuts and washers for the effective clamping of objects. Available with various surface coatings and finishes, including zinc plating, black oxide, and hot-dip galvanizing, our thread stud bolts are built for strength, versatility, and corrosion resistance.
Flybear Fastener offers a comprehensive range of DIN 976 thread stud bolts manufactured from high-grade alloy steel, ensuring durability under extreme load-bearing conditions. With customizable lengths and threading patterns, our bolts suit both standard applications and bespoke orders.

Material and Manufacturing Process
Our DIN 976 thread stud bolts are manufactured using high-strength alloy steel. This choice of material ensures improved longevity, excellent mechanical performance, and superior resistance to fatigue in variable stress applications.
Manufacturing Process:
- Raw material procurement (Certified alloy steel bars)
- Cutting and straightening
- Cold or hot forging
- Thread rolling or cutting (as per DIN 976)
- Surface treatment (zinc plating, hot-dip galvanizing, black oxide)
- Heat treatment (as required)
- Dimensional and quality inspection
- Packaging and marking
Industries and Applications
Thread stud bolts are widely employed in high-stress applications where load strength and vibration resistance are essential. Typical industries and use cases include:
- Power generation and heavy infrastructure
- Automotive engine assemblies
- Oil & gas pipelines
- Wind turbines and renewable energy structures
- Construction and steel fabrication
- Rail transportation and bridges
Their ability to withstand high tension and torque makes them suitable for use in high-pressure joints, exhaust manifolds, cylinder heads, and structural reinforcements.
