Stainless Steel Self Tapping Screws manufacturer in India produce these types of screws in different materials, dimensions, grades and specifications. Suraj Metal Corporationis a leading manufacturer and supplier of the M10 Self Threading Bolts of various kinds. The material for screwing can sometime be soft enough to make a hole with a screw. And the self tapping screws can make the holes as they are driven into the surface.
As such, the 316 SS Self Tapping Screws can make their own holes. The 316 material is strong, corrosion resistant and cost effective for making SS Hex Head Self Tapping Screws. The screws can sometimes have no space to be held with a tool like spanner wrench or hex tools. At these times the Assorted Allen Head Self Tapping Screws can be used. The allen keys can reach the screws from on top of the screws without no need for tools like torque wrenches. There are applications which require high corrosion resistant screws such as the Marine Grade Stainless Steel Pan Head Self Tapping Screws. The applications and materials can be used to harbor the self tapping screws when the gap between the screws and the screw holes has to be minimal. The Stainless Steel 304 Galvanized Self Tapping Drywall Screws have a coating of galvanizing. This improves the low cost material’s corrosion resistance. Please feel free to contact us for more information on the different types of self tapping screws such as SS 316 Heavy Duty Self Tapping Machine Screws and their prices.
