Carbon Steel Chipboard Screw_ Phillips Flat Head Half Thread

Product Description

As the name implies, a drywall screw is used to fasten drywall — wallboard made of a heavy paper-coated layer of gypsum — to framing. The drywall screw is constructed with either coarse or fine threads. The choice of which to use is determined by the type of framing, whether wood (coarse) or metal (fine).

Drywall screw fine thread

These versions of the screw, are preferred for, and can be used to fasten drywall to metal studs as they will easily cut into the metal and provide better holding power in the thin metal, as opposed to the coarse thread verions.

Why Phosphate

Phosphate coatings increase an item's resistance to rust. Additionally, a phosphate coating negates the need for a more expensive paint process. In drywall applications, the screw will be covered in the finished product, where the appearance/color is not a consideration. In instances where exposed metal is part of the finished product, a phosphate coating will convey an even finish while inhibiting corrosion.
