Bolt Nut Protection Caps

 (6 product groups)

What are bolt and nut protection caps?

Bolt and nut protection caps are designed to protect the threads of bolts and nuts from damage, abrasions and corrosion. They are used to conceal exposed nuts and bolt heads to prevent accidental loosening or removal, reduce noise and vibration, and protect the threads from wear and tear. In addition to their protective qualities, they provide an attractive finish to your applications.

Protection caps in our range can be known by many names and variations such as cover caps, nut caps, nut covers and bolt covers, but ultimately they are designed to provide protection to your applications and users.

Common Types & Applications

Nut Caps - provide superior protection for nuts, screws and bolts across many outdoor applications. These caps are resistant to most chemicals, as well as excellent environmentally resistant properties to guard exposed fastening assemblies against the elements. Also known as a nut cover or simply, a nut bolt.

Bolt Caps - provide protection against tampering and weathering for joint fasteners. The caps also provide a clean finish to your applications and are often known by names such as bolt covers and bolt heads.

Secure Cover Caps - snap onto the heads of exposed fasteners to conceal them, offering ideal environmental protection. They are commonly used on children's playgrounds as well as in point-of-sale and furniture applications.

Other types of caps in our range include snap-on bolt caps, snap-on nut caps and domed nut caps.
