Nuts are used in a wide range of structural and fixing applications across commercial and domestic construction. They’re paired with bolts or threaded rods to fasten components like steel beams, timber frames, and mechanical systems. In modern site work, nuts are often selected based on thread size, material, and load-bearing capacity. Stainless steel and galvanised options are common on UK sites due to their corrosion resistance.
You’ll find dome nut types for exposed fixings, where protecting the thread end is important, and hex nuts for standard high-torque assemblies. Thread locking options help manage vibration or heavy loads. Metric sizing is standard, with coarse or fine threads depending on what’s needed.
