With over 150 grades of SS Machine Screws, several industrial sectors prefer using about 15 grades regularly. Out of these 15 grades, the two most important grades are alloy 304 and 316. While grade 304 Stainless Steel Button Head Machine Screws are considered to be cost effective with moderate corrosion.
Their widespread availability and versatility make grade 304 Stainless Steel Csk Machine Screws the most popular alloys around. However, in terms of higher mechanical properties and moderate cost, most Stainless Steel Machine Screw Manufacturers prefer using grade 316. Marine grade or as simply known as 316 SS Machine Screws are well suited to be used for multiple applications. Apart from being used in marine based applications grade 316, Chrome Plated Stainless Steel Machine Screws offer good resistance to oxidation corrosion.
Hence the use of Imperial Stainless Steel Machine Screws in the paper industry is justified. Moreover, the Allen Head Stainless Steel Machine Screws are much tougher and harder in comparison to alloy 304. Therefore they have an extended service life, making them a high value investment across different industries. Speaking about its innumerable uses, the food and beverage industry is not to be left behind. In the food sector, the demand for hygienic constructed equipment is really high.
Since grade 316 Stainless Steel Round Head Machine Screws do not react with the chemicals present in different food and beverage groups such as acids, alkaline and neutral compounds, they are a good fit. Similarly, many manufacturers in the pharma sector prefer using the Black Oxide Stainless Steel Machine Screws to construct non-reactive equipment to produce a non-toxic, yet an effective end product i.e. – medicine.
