Each screw is made from hardened carbon steel with a black phosphate coating, providing light corrosion resistance and a clean, low-glare finish.\u003c\/p\u003e\u003cp\u003eThe bugle head ensures smooth, flush seating without tearing the board’s paper surface, achieving a professional, ready-to-fill finish. The sharp W-type gimlet point allows easy penetration and rapid engagement into timber, reducing driving effort. The coarse thread is optimized for wood substrates, delivering strong bite and resistance to pull-out in natural grain.\u003c\/p\u003e\u003cp\u003eThese 100mm heavy-duty long fixings are ideal for deep board assemblies and heavy timber frameworks.\u003c\/p\u003e\n\u003cdiv style=\"margin-top:30px;\"\u003e\n\u003ch2
