As with the expansion fasteners, the injection fastener is inserted into predrilled holes and the adhesive is injected into the hole. They are bonded in place with two-part chemical compounds epoxies, polyesters or vinylesters. These fasteners can be either surface mounted or injection fasteners using a variety of adhesives or epoxies. Or another way of looking at it is that fasteners tend to be lighter and smaller than anchors although some can be used for both applications. However, attachment of non-structural items to concrete is generally considered to be "fastening", while attachment of structural elements to concrete is considered as "anchoring".
Many people use the two words interchangeably including manufacturers. We also offer tips for properly installing concrete fasteners, including the appropriate tools to use and the mistakes to avoid. Here's an overview of your options and advice on what to consider when selecting a fastener. You have several types of fasteners to choose from, depending on the application and the weight of the item you're hanging. Whenever you affix a nonstructural item to concrete, such as a picture frame, window shutters, or shelving, you'll need the right fastener to ensure a secure attachment.
