The present disclosure provides methods and articles useful in sealing fasteners, including seal caps and in particular translucent or transparent seals or seal caps. In some embodiments, a seal cap which is optically translucent and optionally visibly transparent contains an uncured sealant, which is optionally optically translucent or visibly transparent, and is applied to a fastener. In some embodiments, the sealant is cured by application of actinic radiation to the sealant through the seal cap. In another aspect, a protected fastener construction is provided comprising: q) a fastener; r) a seal cap; and s) a cured sealant; wherein the sealant is optically translucent and optionally visibly transparent.

A plastic expandable bolt thread protector is disclosed that protects the threads of a bolt over which the thread protector is placed either just before shipping a bolt or just before a bolt is put to use. The thread protector is made of a rigid but flexible material having inwardly extending protrusions or pointed segments extending from the wall of the protector into a hollow interior of the protector and when the protector is axially placed over the bolt threads the protrusions or pointed segments create an interference fit with the bolt threads that holds the protector on the bolt threads, and when there is a greater interference fit the wall of the protector deforms and expands outwardly.
