Given the fastening mechanism, it's clear that expansion bolts are typically employed in applications where the standard threading cannot be created. In spite of the numerous similarities that it shares with the nail-in anchors featuring nylon sleeves, these bolts are utilized in heavy-duty applications such
as stadium seating or securing pews. There are several expansion bolt assemblies available, each serving a different role:
: As their name suggests, these fasteners are designed to never be removed. They can be identified by the steel cone covering the head of the bolt.
Permafix Security Expansion Bolts: Commonly used to secure bars and grilles in place.
: Made from steel, the fasteners can be installed and removed via an anti-tamper tool.
Expansion bolts are not only flexible and pliable, but they are also reliable and strong. Perhaps the most appreciated feature is that they are not dependent on the quality of the materials used. For instance, in the construction industry, you can be certain the expansion bolt will continue to do its job, regardless of the quality of the concrete or brick.
A further appreciated is that they allow some room for error. Referring to the construction industry again, these fasteners are flexible enough to ensure a safe installation, despite the fact that the drilled holes present minor misalignments.
