APARELHO PARA MONTAGEM COM FIXADORES |
摘要 |
<p>A device for assembly with a bolt or screw upon installation thereof to prevent tampering therewith, including a jacket member for encircling the enlarged fastener head with a collar portion for disposition adjacent its underside to clamp the jacket member in place upon tightening of the fastener and a cap member configured to fit within the jacket member to enclose the fastener head therewithin. A rounded annular channel is formed within the anterior wall of the jacket member and a square annular rib is formed on the outer surface of the cap member to provide a snap-tight interference fit therebetween. The interior jacket wall and the outer cap surface are also tapered at slightly differing angles to provide a supplementary interference friction fit. The snap-fit between the jacket and cap members is sufficiently strong that they cannot be separated using conventional tools without damaging or destroying the members. A special tool is provided for authorized separation of the jacket and cap members.</p> |
