How should anchorage fasteners be installed?

Anchorage fasteners play a crucial role in ensuring the stability and structural integrity of cabinets, millwork, and finish carpentry installations. The correct method for installing these fasteners is through the back of the cabinet with a minimum of a 3-inch surface bearing head.

This approach is ideal because it allows for a more secure attachment to the wall or supporting structure, providing better support against lateral forces and preventing tipping. The surface bearing head ensures that there is a sufficient area to distribute the load, minimizing the risk of fastener pull-out. Proper installation techniques, including ensuring correct penetration depth and appropriate bearing surface, are essential to meet safety standards and ensure the longevity of the installation.

The other choices present different methods that do not conform to structural best practices for anchoring cabinets. For instance, installing through the front might compromise the aesthetic of the cabinetry and could lead to weaker support due to reduced engagement with the wall. Side installations can similarly risk inadequate anchoring, making the structure more susceptible to instability. Lastly, anchoring through the bottom does not typically provide the level of support needed for tall cabinets and could also lead to failure in the connection.
