Threaded Caps
Our Threaded Protection Caps are made using a strong, quality HDPE Plastic, which is capable of resisting damage and preventing external threads from becoming broken, frayed, or damaged. Each of these Plastic Threaded Caps come with an ergonomic easy gripping head, allowing for fast, efficient screwing on and off from the application.
Our Thread Covering Caps are most commonly used to cover and protect threads whilst in transit. They can also be used for masking purposes to cover and protect a thread whilst coating.
We manufacture these Plastic Thread Protection Caps in three different thread styles and sizes: Metric, BSP, and UNF. We are also able to produce these caps in a range of highly visible colours or custom sizing variants to ensure we have the best possible product for you and your application. Please get in touch with our friendly team if you don't find the part you need.
Benefits of using our Thread Covering Caps:
- Made from a sturdy, reliable HDPE
- Comes with an ergonomic easy to grip head
- Provides an ideal level of thread protection
- Available in Metric, BSP, and UNF thread styles

Frequently Asked Questions
What are the differences between Standard Threaded Caps and Sealing Caps?
The main differences between these products is the fact that one comes with a rubber washer inside the head, this helps to 'seal' off the thread. Standard versions are recommended mainly for protection uses, rather than to provide a quality seal (something often required when working with gas, liquids etc).
What does BSP, Metric and UNF sizing represent?
These units determine the thread type, BSP meaning British Standard Pipe,, Metric being metric standard and UNF being Unified. If you're unsure about what thread to use, please contact a member of our team.
