Structurally, wood screws are a metal rod 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 a wooden frame, etc. These fasteners are made from various types of steel, which is additionally treated with a protective coating to prevent metal corrosion. For example, phosphated screws - the rods of such wood screws are protected against rusting by a phosphate coating. They are typically used to fasten wooden parts and fix gypsum board sheets onto a frame of wooden slats. Our gyproc-wood screws are characterized by: • high strength - they do not break or bend when tightening with a screwdriver, and do not deform under the weight of the connected structures; • reliability - they hold the connection well; • good slot centering, which prevents the tool bit from slipping off the fastener head.
