Hammer fixings are a type of fastener used to attach objects to walls or other surfaces. They are designed to be installed with a hammer, making them a quick and easy option for fixing objects in place. Hammer fixings consist of a screw or bolt that is inserted into a pre-drilled hole in the wall or surface. The fixing also includes a sleeve or plug that is made of a soft material, such as plastic or nylon, which expands when the screw or bolt is tightened. This expansion creates a secure anchor point for the object being fixed. Some of the advantages of hammer fixings include: Quick and easy to install Suitable for use in a variety of wall materials, such as concrete, brick, and stone Provide a strong and durable anchor point Can be used in both solid and hollow walls Resistant to corrosion and weathering When using hammer fixings, it is important to use the correct size and type of fixing for the load requirements and the wall material. It is also important to follow the manufacturer's instructions for proper installation and to ensure that the object being fixed is securely anchored to the wall or surface. Hammer fixings are typically not suitable for heavy loads or applications where a strong and secure fix is essential.
