Self Tapping Metal Screws 3.5x55 Bugle Head Coarse Thread Hard Phosphated
1.Product Description
A drywall screwgun is a specialty tool used for hanging drywall. They are more compact, lighter, and have lower torque than cordless drills.While screwguns do a fantastic of driving drywall screws, they have such limited functionality for homeowners that purchase is unnecessary. We also customize these drywall screws as per requirement into self tapping, so that there is no need to bore holes first. If your cordless drill does not have adjustable speed and a clutch so that you can vary torque, then you will need to purchase one with these features. Heads are especially prone to cleanly breaking off, leaving the shaft section embedded in your wood. The drywall screws are cheap and easy to find. Easy to install. The redundant nature of using multiple fasteners means that the potential for failure is almost non-existent. Bugle head refers to the cone-like shape of the screw head. This shape helps the screw stay in place, without tearing all the way through the outer paper layer. Black drywall screws have a phosphate coating to resist corrosion. Some have a thin vinyl coating that make them even more corrosion-resistant and which make them easier to draw in because the shanks are slippery.
