Description
Their bugle head allows the screw to sink effortlessly into the dry lining without the need for countersinking, which in turn minimises the damage to the surface. Application – Designed for fitting dry linings to studding.Phosphate coatings are made up of thin crystalline layers of phosphate compounds that adhere to the surface of the fixing or fastener. The phosphate crystals are porous and can be formed from zinc, manganese, or iron phosphate solutions.The Phillips screw has four simple tapered slots. It is designed so that a Phillips tip screwdriver can turn a Phillips screw with increasing torque. When the torque gets to be too strong for the tip then the screwdriver tip winds itself out of the screw thus preventing over-tightening and or damage to the screw head. Coarse thread screws (mainly drywall screws) have an extremely sharp point and are designed to penetrate plasterboard skin. The coarse thread eases in to the board then the timber baton holding the board firm. QUALITY: SS8 drywall screws are constructed from durable carbon steel making them really strong and long-lasting. The plaster board fixings are rust resistant and corrosion resistant even in humid environments. SELF DRILLING: The wall screws sharp piercing point means that with these self drilling screws there is no need to drill a pilot hole . The thread surface is smooth and burr-free so the plasterboard fixings are not likely to slip during installation. FEATURES: These dry walling screws are made from C10-18 Steel and surface hardened up to 750 HV to prevent torque shearing under load. The sharp point of the wood screw reduces the tearing of the plasterboard. SS8 Screws Black for Wood Plasterboard Drywall Corse Thread Black Phosphate.
