What Are Domed Hex Nuts?
Domed hex nuts, also known as cap nuts, are hexagonal nuts with a closed domed top. They tighten like a standard hex nut while covering the end of a bolt or stud to protect the thread and deliver a clean finished appearance. This makes them well suited to exposed fasteners where safety, corrosion protection and presentation matter.
Applications and Key Industries
These domed nuts are widely used across the UK where a protected thread end and tidy finish are required, including general fabrication, automotive trim and assemblies, enclosures, furniture and fittings, guarding, plant maintenance and light structural builds. They are commonly specified by engineers, maintenance teams and trade installers who need reliable fastenings that also improve safety and appearance.
