Drywall Screws Fastening

Posted by Li Li over 6 months ago

Drywall screws are the most common fastener used to install drywall. There are basically two types of screws used for drywall, coarse thread and fine thread drywall screws. Fine thread drywall screws are made specifically for use with galvanize steel stud profiles (http://www.adtomall.com/galvanize-steel-stud-profiles-with-the-best-price). Fine thread screws can be used when installing drywall on wood studs. However, coarse thread screws are better suited for wood stud framing. Coarse thread screws drive into wood slightly faster than fine-thread and bite stronger in the wood below. Coarse thread drywall screws should never be used with steel stud framing. Self-tapping fine-thread drywall screws are useful for installing drywall on steel stud framing, particularly when installing drywall over heavy gauge steel studs. The second main consideration with drywall screws is the length. Drywall screws come in a variety of lengths. The most commonly used length is 1-¼ and 1-⅝ inch long drywall screws. The shorter the screw, the easier it is to install. Long screws have a tendency to lean over so you have to be extremely careful to keep them strait when pushing them in with the screw-gun. Even the slightest pressure off-center will tip them over. When installing either ½ or ⅝ inch drywall, 1-¼ inch drywall screws are the length of choice. Double layer drywall requires longer screws, usually at least 1-⅝ or even 2 inch drywall screws. When choosing screw length it is best to go with the shortest possible length that allows the shank to sink at least ½ inches into the stud below.
