Product Description

                                                                      Self Drilling Screw

Pozidriv screws are externally threaded fasteners with torqueing heads, which feature a cruciform socket with radial indentations that are set at 45 degrees from the main cross.
Pozidriv describes the screw drive type of the socket and driver, and is one of the most common screw drives used worldwide. Often abbreviated to PZ or PSD, or mistakenly spelled, "Pozidrive".

Type:	Self Drilling Screw
Definition:	As the name implies, self-drilling screws do not require a pilot hole in order to perform as a fastener. Since self-drilling screws do not require a pilot hole, they can rapidly and efficiently connect a variety of materials, which enhances productivity and performance.
Description:	What is the difference between self drilling screws and regular screws? Self-tapping and traditional screws have a similar design consisting of a head, shank and tip. Only the former, however, are designed to produce their own hole. Traditional screws typically require the use of a pilot hole, which is how they are distinguished from self-tapping screws.
Application:	Self-drilling screws can be used to fasten sheets of metal to another material, or even to join metal to metal. Not only does this set them apart in comparison to other common screw types, but it also makes them highly useful across a broad spectrum of industries and applications.
Others:	How can you tell if a screw is self tapping? Self tapping screws have pointed tips designed to be inserted into pilot holes or softer substrates. Self-drilling screws are distinguished by having an effective drill bit at the tip of the screw.
