Fine Thread Hex Head Self Drilling Screws

The Fine Thread Hex Head Self Drilling Screw is a fastener that combines a self‑drilling tip with a hexagonal drive, allowing the screw to create its own pilot hole. It features a fine thread profile that is suited for precise fastening in softer substrates such as wood and plastic. The supplier notes that the design prevents the tip from binding or breaking during installation. The product is offered in three material finishes - stainless steel, carbon steel and alloy steel - and the supplier recommends the use of a washer to maintain long‑term joint integrity.

In the fastener market, fine‑thread self‑drilling screws are commonly supplied in metric diameters from M3 to M6 with lengths ranging between 20 mm and 100 mm, which matches the typical size envelope for furniture and appliance assemblies. Stainless steel grades such as 304 or 316 provide a typical tensile strength of about 800 MPa and superior corrosion resistance, while carbon and alloy steel variants are chosen for cost‑sensitive projects requiring moderate wear resistance. Zinc plating is a standard coating applied to improve surface hardness and reduce rust in humid environments. Industry standards such as DIN 7509 and ISO 10642 define the dimensional tolerances and head height for hex‑drive self‑drilling screws, ensuring interchangeability across manufacturers.

These screws are widely used by manufacturers of flat‑pack furniture, kitchen cabinet frames, electrical enclosures and light‑weight metal housings where a quick, pilot‑hole‑free assembly is valuable. Importers typically request bulk cartons packed in cardboard, with the exact quantity to be agreed per order. Because the listing does not disclose minimum order quantities, lead times or payment conditions, buyers should confirm these details directly with Hellary Import And Export Private Limited before placing a purchase. Clarifying the required incoterm - for example FOB Rajkot or CIF Mumbai - will help avoid unexpected freight costs.
