Threaded Plugs

Variations Of Threaded Plugs

Metric Threaded Plugs
These Metric plastic threaded plugs are an ideal solution for insertion into threaded holes, providing an excellent level of protection and coverage, with a flanged head for further protection around the lip of the thread.
BSP Threaded Plugs
Plastic threaded plugs are made from a hard yet durable plastic which provides excellent protection benefits when placed inside a thread. Available in a huge range of thread sizes and lengths these are a cost effective solution for a number of high end products, preventing costly damage that can be avoided.
UNF Threaded Plugs
Plastic threaded plugs with a UNF style thread are a cost effective style of protection plug or thread protector. Being made from a premium hard red plastic with an ergonomic grip head, they are also an easy to fit solution simply screwing into place.
Our Plastic Threaded Plugs are produced from a highly durable Low Density Polyethylene Plastic which allows for good protection of internal threads and prevention of Damage, Moisture, Corrosion and Dirt. Thread Protection Plugs are especially useful within Hydraulic and Engineering related industries where the cost of equipment outweighs the typically low cost of protection methods. As an easy and efficient product to install these simply screw into your desired thread with strong protection properties to prevent deterioration over time through liquid ingress, or oxidisation. Finished in Red these are designed for easy visibility and removal, so can be used both during storage, transport or as general protection elements. 

We stock these Threaded Protection Plugs in a number of different standard thread types including BSP, Metric and UNF (or unified) each with a number of potential sizing options ranging from M10 all the way up to M42 ensuring we always have the protection solution that you require. Please click through to your required thread type below before viewing all of the sizes available.
