Self Threading Nut Caps

Our Self Threading Nut Caps, also known as Thread Caps, Nut Caps or Bolt Caps, are made from high quality LDPE anmd are designed to be easily installed to protected exposed threads. These Stud Protection Caps are used to conceal fasteners, but can also offer protection to the otherwise exposed threads from dirt, damage, corrosion or injury.

Our Self Threading Nut Caps are designed to be screwed onto the thread of an existing stud or bolt, where the internal ribs are threaded as the cap is inserted. This provides a strong connection, making it hard to be accidently removed, and provides and excelent seal around the bottom lip protecting the fastener from the elements. Our Self Threading Nut Caps have a hex head allow the user to use a spanner or wrench when threading this cap onto the bolt or stud. Our range is suitable for threads from M36 to M48, and are available in several lengths per size. 

Our range comes in black as standard, but we are able to offer custom batches in any RAL colour required. For further info on custom colour runs, please get in touch on 01233 713581.
