What is Black Drywall screw

Drywall screw, also known as Prince fastener wallboard screw. Used for the connection of plasterboard to wooden keel and
plasterboard to light steel keel.

Generally available on the market in black, i.e. black phosphated. Blue and white ones are also available, i.e. blue-zinc. There
are probably not many domestic ones in blue zinc.

More than 80% of the demand for prince fastener Black Drywall screw is concentrated on the one size 3.5×25. This is because they are mainly used in plasterboard, which is all the same thickness. I have seen some TX say that this type of prince fastener screw is also used for hitting furniture, which is actually inappropriate. Just like you wear a pair of leather shoes to run, run can also run, but certainly sneakers are more appropriate.

 

 

The criteria for buying Black Drywall screw

1. The head should be round (this is also a common standard for all round head screws), because of the production process, many manufacturers produce a Black Drywall screw head may not be very round, some are even slightly square. The problem is that after screwing into the plasterboard can not be fully matched, concentric circles, around a central point of rotation, this should be well understood.

2. The tip should be pointed, especially if you are using it on a light steel keel. Prince Fastener Black Drywall screw generally
require a sharp angle of 22 to 26 degrees, requiring a head full of sharp corners, not dragging wire, cracking phenomenon. The “tip” of the Black Drywall screw is the most important, because the use of Prince fastener drywall screw do not play prefabricated
holes, directly screwed, so the tip also assumes the function of drilling through. Especially when used on light steel keel, a
bad tip can lead to a lack of drilling, which directly affects the use. According to national standards, Prince fastener wallboard screw should be able to drill through 6mm iron plates within 1 second.

3. No eccentricity. The easiest way to determine if a drywall nail is eccentric is to place the round head down on the table and see if the threaded part is vertical and in the middle of the head. If the prince fastener screw is off-centre, the problem is
that it will wobble when screwed in with a power tool. Short screws are fine, but if a longer screw is in this situation it will be a big problem.

4. The cross slot should be in the middle of the round head, otherwise it is the same as in 3.
