Socket Head cap screw
Socket Head Cap Screws are high-strength threaded fasteners with a cylindrical head and a recessed hexagonal drive. Designed for use in assemblies with limited space, these screws allow high torque tightening using an Allen key or hex driver, making them ideal for precision applications.
Manufactured from premium materials such as alloy steel, stainless steel (SS 304, SS 316), and titanium, these screws are available in various grades and finishes including black oxide, zinc-plated, and hot-dip galvanized. They conform to international standards such as DIN 912, ISO 4762, and ASTM A574.
High Torque. Compact Head. Precision Fastening.
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.
At our company, we don’t just supply hardware — we engineer reliable fastening solutions tailored to your project needs. Whether you’re building infrastructure or assembling precision machinery, our extra long nuts are the dependable choice for strength and longevity.
