Half Round Bolt
Half Round Bolts feature a distinctive semi-circular or domed head and are typically used in applications where a low-profile finish and smooth surface are required. The rounded top prevents snagging, damage, or interference with moving parts, making them suitable for both functional and aesthetic installations.
These bolts are manufactured with full or partial threads and are available in various materials such as mild steel, stainless steel, and high-tensile alloys. They are often paired with nuts or embedded directly into surfaces depending on the requirement.
Smooth Profile. Strong Grip. Lasting Hold.
Extra long nuts, also known as coupling nuts or extended hex nuts, are commonly used in mechanical, structural, and heavy engineering applications. Their primary function is to connect two male threaded rods or to provide deep thread engagement where high clamping strength is essential. These nuts are particularly useful in:
Steel fabrication
Heavy machinery assembly
Bridges and structural supports
Wind turbine installations
Automotive and aerospace components
Pipeline and oil & gas equipment
Due to their extended length, they offer greater thread engagement compared to standard nuts, minimizing the risk of loosening due to vibration or load stresses.
Extended Thread Depth: Offers superior load distribution and grip over longer threaded sections.
High Tensile Strength: Manufactured from carbon steel, alloy steel, or stainless steel, depending on the requirement, for superior performance under high-stress environments.
Precision Machining: Each nut is precisely machined using CNC technology to ensure tight tolerances and perfect thread alignment.
Corrosion Resistance: Available with coatings like black oxide, hot-dip galvanizing, or zinc plating to resist corrosion and environmental wear.
Customizable Dimensions: We can manufacture extra long nuts in various sizes, diameters, and thread standards (metric, UNC, UNF, etc.) as per client specifications.
Enhanced Holding Power: The extended length allows for a larger surface area contact, reducing stress and the likelihood of failure.
Durability in Harsh Conditions: Ideal for outdoor or high-vibration settings where standard nuts may fail.
Versatility: Suitable for both temporary and permanent joints across diverse industries.
