Snap-on Bolt and Nut Protection Caps are supplied in a variety of sizes to suit your application. These standard caps protect washers, as well as bolts and nuts. Our LDPE option features an extendable head that is suitable for large studs and helps protect against weathering and tampering, while providing more of a finished appearance and is available in a choice of colour options. Our brown PEEK option is a lightweight but tough alternate, giving them excellent mechanical, steam and boiling water resistance. Our Bolt Protection Caps are a suitable match for our range of Hexagonal Head Screws and Hexagonal Bolts.
