Fixed Competitive Price Short Drywall Screws - Black Phosphated Bugle Head DIN7505 Drywall Screw – Xinruifeng Detail:

1. The Drywall Screw is characterized by a bugle head that features a flat top and a concave under-head bearing surface. For this reason, the Drywall Screw is also called Bugle Head Screw. This unique design enables the distribution of the bearing stress over a much wider area than is with a flat head screw.

2. The bugle head offers many benefits which are the followings:
● The bugle head screw has a smoother transition between the shank and the head, which avoids the material to get caught, resulting in a more attractive finish.
● The bugle head can depress sufficiently the surface of wood material without breaking it, which minimizes the risk of damage to the finished product.
● Like the countersunk head, the bugle head also makes the drywall screw lie flush in the material, which makes it a versatile fastener in numerous construction tasks.

Drywall screw:

1.Heat treatment: It is a method of heating steel to different temperatures and then using different cooling methods to achieve different purposes of changing the properties of steel. The commonly used heat treatments are: quenching, annealing, and tempering. What kind of effects will these three methods produce?

2.Quenching: A heat treatment method in which the steel is heated to above 942 degrees Celsius to make the steel crystals in austenitic state, and then immersed in cold water or cooling oil to quench to make the steel crystals in a martensitic state. This method can increase the strength and hardness of the steel. There is a very big difference in the strength and hardness of the steel with the same label after quenching and without quenching.

3.Annealing: A heat treatment method in which the steel is also heated to an austenitic state and then naturally cooled in air. This method can reduce the strength and hardness of the steel, improve its flexibility, and facilitate processing. Generally, steel will go through this step before processing.

4.Tempering: Whether it is quenched, annealed or press-formed, steel will generate internal stress, and the imbalance of internal stress will affect the structure and mechanical properties of the steel from the inside, so a tempering process is required. The material is kept warm continuously at a temperature of more than 700 degrees, its internal stress is changed and then cooled naturally.

Bugle head drywall screw allows you to make the attachment point even, without protrusions, which is important if this is required by technology or the designer’s idea. The bugle head is recessed into the attached material, drywall, by 1 mm and has a cross-shaped slot PH (Phillips), one of the most common in construction. Screwing can be done as a screwdriver, and for efficiency – with a screwdriver.

However, you need to have a certain skill when using a power tool. The standard sheet has dimensions of 2500x1200x12.5 mm. For ceiling structures, a lightweight analog with a thickness of 9 mm is used; for arched – 6 mm.

The most popular, and hence the best-selling, size of the drywall screw is a fastener 25 mm long – a universal length to fit the attached sheet and firmly entrenched in a metal base.

Long drywall screws are a rare product and are in demand when, for example, it is necessary to additionally fix the structure to a surface that is some distance from the main working one.

The sharp tip of gypsum drywall screw is a design feature that makes the drywall screw in fixing drywall to a metal frame. The tip of the product produces the same self-tapping action, which greatly simplifies the fastening process.

Drywall screws are made of carbon steel, which has increased strength. To increase the service life of hardware, they are covered with an anti-corrosion layer by phosphating (applying a protective film consisting of metal phosphates) or galvanizing (treatment with white or yellow zinc).

Black drywall screws are ideal for further painting, as paintwork materials adhere especially well to phosphated drywall screws.
