Product Description

When you are looking for fasteners, you are trying to evaluate the situation and pick the best way to put materials together. Fastening one or more pieces of light, medium, or heavy gage sheet metal together may require the use of adhesives, riveting, or self-tapping screws. If an application requires access or several layers, tapping screws maybe the best option.

First of all, what is a self-tapping screw? Tapping screws are designed to cut their own hole as it is screwed into the materials. This creates a good snug fit between the mating threads and also allows the parts to be reassembled if necessary.

The advantage of the flat-tipped screw is that it won't get stuck in the material and break off.The type B tip is blunt and intended for use with a pilot hole, often in sheet materials. The lack of a sharp tip is helpful for packaging and handling and in some applications may be helpful for reducing the clearance necessary on the reverse of a fastened panel or for making more thread available on a given length screw.

Product Specification

How do you use self-tapping screws?

Self-tapping screws drill their own little tunnels by cutting precise threads when they are screwed into wood, plastic or metal. It's helpful to use self-tapping screws for products that you need to maintain regularly such as air-conditioning units or canopies where you need to dissemble and reassemble the item along the same threads. You can insert self-tapping screws with either a hand-held or electric screwdriver.
