About Heavy Hex Nuts

Heavy hex nuts are similar to standard hex nuts but feature a larger width across flats and increased thickness. This design provides greater strength and surface area for load distribution, making them ideal for high-stress environments. These nuts are commonly used in heavy construction, structural steel applications, and with large-diameter bolts in critical installations where strength and durability are crucial.

At Teshi Fasteners, our heavy hex nuts are manufactured to meet the highest industry standards, ensuring they perform reliably under the most demanding conditions. Available in materials such as carbon steel, alloy steel, and stainless steel, our heavy hex nuts are designed to withstand extreme stress and harsh environmental conditions.

Key Features of Heavy Hex Nuts

Increased Size: Larger across flats and thicker than standard hex nuts, providing greater strength and durability.
Enhanced Load-Bearing Capacity: Designed to handle higher stress and torque, making them suitable for heavy-duty applications.
Robust Construction: Typically made from strong materials such as carbon steel, stainless steel, or alloy steel, ensuring long-lasting performance.
Corrosion Resistance: Available in various coatings like galvanization, PTFE, or zinc plating to enhance resistance to rust and corrosion, especially in harsh environments.
Precision Threads: Manufactured with precise threading for secure and tight fastening, ensuring reliability in high-pressure applications.
Compliance with Standards: Adheres to international standards such as ASME, ASTM, DIN, and ISO, ensuring consistent quality and performance.
Versatility: Suitable for use in a wide range of industries, including construction, oil and gas, heavy machinery, and power generation.

Benefits:
