Drywall Screws and Stainless Steel Screw manufacturer in India
Are Stainless Steel Screws Stronger Than Steel Screws?
A steel screw is produced by adding iron and carbon. A stainless screw on the contrary, are designed possessing high chromium content. Comparing the strength of steel and stainless steel is a very common misconception. Steel is slightly stronger than stainless steel screws as the lower carbon content in SS cannot be hardened.
What Is The Difference Between A Machine Screw And A Wood Screw?
Machine screws are threaded across their entire body. A wood screw is not threaded across its length and has less number of pitches than its counterpart. Machine screws have precision threading, while the latter has coarse threads. Machine screws are preferred in applications that require self-locking. Wood screws are generally affixed with nuts to hold them in place.
What Is A Standard Drywall Screw?
A standard Drywall screw is a specialized self-tapping screw. Designed with a bugle head, these screws attach drywall to studs. These screws are a standard fastener for securing full or partial drywall sheets with ceiling joists. The screws are designed in standard lengths of 1/4, 1/2, and 5/8 inches. Each of these screws is available in different specifications as per customer requirements.
Do Concrete Screws Need Plugs?
Concrete screws provide a quick and easy way of fastening concrete. There is no hammering or anchoring required to shield the material. All that is required is to create a hole and drive the screw. In most cases, they don’t need any plugs, but you can install plugs, so the threads are better aligned.

Metal screws are threaded through the entire body, while wood screws are not. Furthermore, metal screws have more pitches — number of threads per inch — than their wood screw counterparts. It's also worth noting that metal screws are preferred for applications where self-tapping is needed.
