Product Features

1. The Drywall Screw is characterized by a bugle head that features a flat top and a concave under-head bearing surface. For this reason, the Drywall Screw is also called Bugle Head Screw. This unique design enables the distribution of the bearing stress over a much wider area than is with a flat head screw.
2. The bugle head offers many benefits which are the followings:
● The bugle head screw has a smoother transition between the shank and the head, which avoids the material to get caught, resulting in a more attractive finish.
● The bugle head can depress sufficiently the surface of wood material without breaking it, which minimizes the risk of damage to the finished product.
● Like the countersunk head, the bugle head also makes the drywall screw lie flush in the material, which makes it a versatile fastener in numerous construction tasks.
