black self drilling screws

Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.

The fully threaded rod 1/4, as the name suggests, is a long, slim rod with threads running along its entire length. The diameter of the rod measures a quarter of an inch, hence the 1/4 designation. These threads are typically standardized, ensuring compatibility with a wide range of nuts and accessories. Made from durable materials such as stainless steel or brass, these rods are built to withstand significant force without yielding or breaking.
