Threaded Plugs

Variations Of Threaded Plugs

Screw In 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.
Our Plastic Threaded Plugs are produced from a highly durable and strong Polyethylene plastic which allows for good protection of internal threads and prevention of damage, moisture, corrosion and dirt when in use. These Plugs are easy and efficient to install, simply screwing into the thread using the ergonomic grip-head. Our Threaded hole plugs have been designed to work as a cost effective thread protection solution, being massively popular inside the hydrualics and engineering industries due to their strong protection properties which prevents damage to high end items. 

We stock these Threaded Hole plugs in a number of different thread types including BSP, Metric and UNF. 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.
