Idea for hardware thread lock and tamper indicator.

How about fastener washers, bolts, or nuts with adhesive or thread-lock compound encapsulated within.  This compound would then squeeze out as the fastener is tightened and thus secure the attachment.  

This might be less costly than current locking fasteners and yet get the same result.  The compound could also be colored to signal to the user that the fastener is secure.  

This signal feature could also be used to signal tampering after the fastener was secured.  Currently, a common practice to prevent fastener tampering is to paint the surface around the fastener.  With this compound on the fastener already – an extra assembly step might be saved.
Possible Start Building Blocks –

• Existing concepts for self-locking hardware, tamper-proof openings, tamper indicating fasteners, caulking, liquid-center candy, etc.


• USPTO Class/Subclasses for "How-To" ideas – 427/510, 411/258
