Drywall screws have become the standard fastener for securing full or partial sheets of drywall to wall studs or ceiling joists. Drywall screws' lengths and gauges, thread types, heads,points, and composition at first might seem incomprehensible. But within the area of do-it-yourself home improvement, this vast range of choices narrows down to just a few well-defined picks that work within the limited types of uses encountered by most homeowners. Even having a good handle on just the three main features of drywall screws will help: drywall screw length, gauge,and thread.
For most work involving 1/2-inch drywall on installed on wood studs, the phosphate coated, coarse thread 1 1/4-inch or 1 5/8-inch drywall screw does a reliable job. This screw is inexpensive and can be purchased in large tubs, since drywall work requires a multitude of fasteners. The 1 5/8-inch drywall screw can be difficult to sink, since so much shaft remains after the first 1/2-inch of the drywall thickness is covered. Stepping back on length means easier driving but it also does mean reducing holding strength. Since the last 1/8-inch of sink is critical (where the bugle head of the screw needs to crease but not tear the outer paper layer), this shorter screw makes it easier to calibrate that last 1/8-inch of drive.
