Pan / Phillips / Hex Head Self Tapping Screw manufacturer in India

Self tapping screws are a special type of screws that bore their own pilot holes. They have a special design with a tip that acts like a drill bit. Jignesh Steel is a manufacturer and supplier of Stainless Steel Self Tapping Screws of different types. We manufacture and supply different types such as the SS 304 Phillips Pan Head Self Tapping Screw. The basic shape of this type of screws is round and there are some variations of it as well. The material of the screws can vary. The 316 Stainless Steel Self Tapping Screws are common as they are stronger enough to bore their own holes in a variety of material surfaces.

Due to the abrasion during fixing, the screws need to be stronger and corrosion resistant after installation. The 316L Self Tapping Screws & Tapping Bolt are made up of nickel chromium and molybdenum alloy metals so that they remain corrosion resistant after installation as well. There are different dimensions of the screws. The head, the diameter and the length can all vary with different types, specifications and standards of the screws. The 30 X 4mm Self-Tapping Screws In Stainless Steel for example have a 30mm length and the diameter at head at 4mm. We also produce smaller scaled Stainless Steel Self Tapping Screws 5/16 8mm as well as some large scale screws. Please contact us for a full list of self-tapping screws and prices.
