Bolt Protection Caps

What are Bolt Protection Caps?

Bolt caps, an essential addition to fastening applications, serve to enhance the aesthetic appeal and protection of exposed Bolt heads. These functional components are designed to push fit over exposed bolts, providing a finished appearance whilst also shielding the heads from external elements. Whether in assembly or machinery, bolt caps play an instrumental role in ensuring that mechanical connections are not only visually appealing but also free from snagging, corrosion and damage.

How Bolt Caps Work.

The functional efficacy of bolt caps lies in their simplicity. By covering exposed bolt heads, bolt cover caps contribute to the seamless concealment and blending in of bolts to match their environment in a similar fashion that nut caps do. Also acting as covers, they are often utilized to prevent moisture, dirt, and other external agents from reaching the head, thereby reducing the risk of rust and wear. Finally, combining bolt caps and heavy machinery also presents protection for the human element by reducing any snagging risks.

What Material Bolt Caps Are Made From.

Recognizing the demands of various applications, Accu's bolt caps are manufactured using a selection of diverse materials, each offering unique characteristics. Our plastic bolt caps are known for their lightweight and corrosion-resistant nature, making them suitable for general applications. Similar to rubber bolt caps, our PVC range offers flexibility and a snug fit, providing extra protection when it comes to coating processes similar to that of masking caps.
