Use of self drilling screw

How to use the self drilling screw?

Screws, especially self-drilling screws, among other building materials, will only perform to their maximum potential when chosen correctly, and then installed properly.

Xiaojun Fasteners offer a complete range of self-drilling screws in different gauges, lengths, corrosion resistance, and unique designs to enhance mechanical properties and performance.

The important aspect of how to use self-drilling screws is the installation. The importance being that it correlates with the longevity of not only the self-drilling screws in itself, but the structural integrity of the joined material, and lifespan of the structure as a whole.

    2.Check the maximum drilling capacity of the screws. If the thickness of the metal substrate exceeds the maximum capacity, you should choose a longer screw.

    3.Check if the corrosion resistant level is suited for your environment. For example, if you bought a simple, yellow zinc plated screw and expect it to last in coastal areas, think again.

    4.Check the maximum recommended RPM (Rounds Per Minute) allowed during drill & drive. Exceeding the maximum RPM recommended by manufacturers during drill & drive is a recipe for 

disaster,as it will most definitely result in tip burnout and failure. Always err on the safe end and use a hand-tool with a torque limiter.

  5.Do not over-drive screws. Over-driven screws have a tendency to crush the EPDM washers or rubber gaskets intended to create a tight weather seal over the hole between the screw head and affixed metal

substrate.

    6.Do not under-drive screws. Aside from not being able to fasten substrates tightly together, under-driven screws fail to provide sufficient pressure over the hole between the screw head and affixed metal

substrate to create a weather-tight seal.

    7.Always check the perpendicularity of the screws in relation to the drilled substrate during the drill and drive process. There is little to no chance of correcting a crooked driven screw, and normally a new hole

has to be driven somewhere alongside the failed one.  Washers on the skewed screw may also damage the substrate itself if it happens to be of a softer material such as plastic.
