Structurally, wood screws consist of a metal shank with a wide thread pitch applied at a 40-45 degree angle, a sharp tip, and a head. Such fasteners are used when cladding surfaces with wood panels, joining chipboard or plywood parts, assembling drywall structures on wooden frames, etc. These fasteners are made from various types of steel, which is additionally treated with a protective coating to prevent metal corrosion. For example, phosphatized screws—the shanks of such wood screws are protected from rusting by a phosphate coating. They are typically used to fasten wooden parts and fix drywall sheets to wooden slat frames. Our Giprok-wood screws are characterized by: high strength - they do not break or bend when driven with a screwdriver, and do not deform under the weight of the connected structures; reliability - they hold the connection well; good drive centering, which prevents the tool bit from slipping off the fastener head.
