Product Description
What is Drywall screw?Drywall screw, also known as drywall nail is suitable for interior decoration partition ceiling, keel and gypsum, calcium silica board fixing, the material is 1022A steel, the product shall be heat-treated and hardened to HV450-750 degrees, surface antirust is divided into galvanized, color zinc gray phosphorus, black phosphorus, the latter two antirusts is the strongest antirust is not vital will cause the wall to have rust.
More than 80% of the demand for drywall screws is concentrated on 3.5x25 this specification. Because they are mainly used for gypsum board, and the thickness of the gypsum board is the same.How to choose drywall screw?1 head to be round (this is also a common standard for all round-headed screws). The production process, many manufacturers, produce a drywall screw head may not be very round, some even slightly square. The problem is that after screwing into the plasterboard can not be matched entirely with the concentric circles around a central point of rotation, this should be very easy to understand.
2. the tip should be pointed, mainly when you are used in a light steel keel. Drywall screw generally requires the tip angle in 22 ~ 26 degrees between the head tip full requirements and can not drag silk, cracking phenomenon. This "tip" for drywall nails is the most important because the use of drywall nails do not hit the prefabricated hole directly screwed, so the tip also assumed the function of drilling through. When used in the light steel keel, the wrong direction will lead to drilling directly affect the use. According to national standards, the wall plate nail can drill through a 6mm iron plate in 1 second.
3. Not eccentric. The easiest way to determine whether the drywall screw bizarre is to round head down on the table, see if the threaded part is vertical, and live in the middle of the head. If the screws are eccentric, then the problem is that the power tool will be shaken when screwed into. Shorter screws are fine, but if longer screws encounter this situation, it will be a big problem.
4. The Phillips groove should be in the center of the round head. Otherwise, it is the same as the case of 3.Specification of drywall screwModel No.:C1022
