Nut and Bolt Protecting Caps

Protecting Caps
Bluemay protecting caps are ideal for encapsulating metal hexagon nuts or bolt heads. They give a smart appearance as well as being practical, lightweight and easy to fit but are extremely effective protection against rusting, and damage from snagging.

Bluemay protecting caps are available as standard in white, black or grey but can be manufactured to match almost any colour of your choice. Standard thermoplastic materials are LDPE (low density polyethylene).
