Stainless steel self drilling screw material is generally 410 material, commonly known as stainless iron, is a general martensitic stainless steel, can do heat treatment, high hardness, without surface treatment can play a certain surface anti-corrosion effect, anti-rust ability is better than carbon steel,worse than 304 stainless steel, can hit through iron plate, fastening the use of steel plate.It is mainly applied to the steel plate connection or the fixed connection of other stainless steel materials.Stainless steel self drilling screws according to the shape of the head can be divided into: hexagonal self drilling screw, countersunk head self drilling screw, pan head self drilling screw, Wafer head self drilling screw.

410 Stainless Steel Wafer Head Philips Self Drilling Screws for Home & Industrial Use Ensures correct hole size every time, resulting in better thread engagement and tighter clamp Drilling hole upto 4 mm in M S Sheet Drill Hole & Forming mating thread Clamping at home can achieve in an easy operation. It only needs one tool for application screw drive & Screwdriver Bit with Magnetic Ring Adopter. These self-drilling screws are highly versatile and are used to attach to metal, wood, fiberglass and plastic. The sharp threads draw material together and ensure a secure hold. There is no pre-drilling required for these screws. Self-drilling screws can drill its own hole and tap its own thread as it is driven into the surface. Application: profile sheets, fiber sheet, MS sheet, MS angle, MS pipe, MS pipe, metal to metal, wood to metal, fiber to metal , 410 stainless steel has high strength and hardness ratings and resists corrosion in mild environments ? It is wood drill tail screw, mainly used in steel structure caigang watt fixed can also be used for fixing the simple construction of the sheet material.
