Heavy-Duty Bolting Solutions: Your Trusted Supplier of Heavy Hex Flange Bolts and Shoulder Bolts Across the USA

When it comes to industrial-grade fastening solutions, precision, durability, and performance matter the most. Whether you’re working on a construction project in New York, managing infrastructure maintenance in New Jersey, or leading an engineering project in Chicago, having the right bolts is crucial. That’s where we come in—G-Fast proudly supplies USA-made heavy hex flange bolts, custom shoulder bolts, and A490 heavy hex bolts that meet the highest standards of strength and reliability.

Why Choose Heavy Hex Flange Bolts?

Heavy hex flange bolts are a preferred choice in structural and industrial applications due to their wide bearing surface, increased clamping area, and resistance to loosening under high-stress environments. Unlike standard bolts, the heavy hex head design provides extra strength and torque handling, making them ideal for:

• Steel-to-steel structural connections

• Heavy machinery installations

• Bridge construction

• Wind turbine assemblies

In areas like New York, New Jersey, and Chicago, construction codes and industrial standards demand high-performing components. That’s why our heavy hex flange bolts are manufactured to meet ASTM and SAE specifications, ensuring long-term performance in demanding environments.

A490 Heavy Hex Bolts – Built for Structural Strength

Another key product in our inventory is the A490 heavy hex bolt, a structural bolt used in steel connections that require high strength. These bolts are made from alloy steel and heat-treated for exceptional tensile strength. A490 bolts are typically used in:

• High-rise steel buildings

• Large infrastructure projects

• Heavy equipment installations

• Bridges and highways

We supply A490 heavy hex bolts in bulk quantities across the USA, including direct deliveries to project sites in New York, New Jersey, and Chicago. These bolts are designed to resist corrosion and endure harsh environmental conditions, helping contractors maintain safety and compliance.

Custom Shoulder Bolts – Precision Fasteners for Specialized Applications

In addition to structural bolts, we provide custom shoulder bolts for projects that require precise alignment and smooth rotational motion. These bolts, also known as stripper bolts or shoulder screws, have a cylindrical, unthreaded shoulder between the head and thread, allowing components to move or pivot with control.

Common industries using custom shoulder bolts:

• Aerospace

• Automotive

• Manufacturing automation

• Medical equipment

Our team at G-Fast works with clients to manufacture custom shoulder bolts to exact dimensions, tolerances, and finishes. Whether you’re looking for prototypes or full-scale production runs, we’ve got the tools and expertise to deliver.

Metric Shoulder Bolts – Reliable for International Standards

For projects that follow metric standards, we offer a wide selection of metric shoulder bolts in different diameters and lengths. These are widely used in imported machinery or for global companies with standardized practices.

G-Fast ensures that all metric shoulder bolts meet ISO or DIN standards, making them compatible with global equipment specifications. We ship across the USA and are fully equipped to meet urgent demands from Chicago, New York, New Jersey, and beyond.
