Stainless Steel Self Tapping Screws
Stainless Steel Self Tapping Screws are made for soft material surfaces. These screws can drill their own pilot holes as they are driven in. The ss self tapping screws come in material grades such as the 304, 316 austenitic stainless steels, alloy steels, duplex steels and carbon steel materials. Some of the self-tapping screws are also high tensile screws made up of high tensile materials.
Stainless Steel Self Tapping Screws
Hex Head Self Tapping Screws
Pan Head Self Tapping Screws
There are different types of the heads such as the ss pan head self tapping screws. The pan head enables for special installation purposes. Material surfaces such as aluminum and wood are where these self-tapping screws are mostly used. The Pan Head Self Tapping Screws can come in different dimensions starting from 1 inches to 24 inches in sizes. The length of the screws can range from 3mm to 200mm for different application types. The material grades are chosen for the environmental conditions. The 316 SS Self Tapping Screws are resistant to chloride ion stress and corrosion. Therefore these are preferred for seaside furniture, seawater applications, marine and shipbuilding applications as well. The application of most self-tapping screws can be seen in the making of furniture, computer hardware, aluminum paneling and other paneling applications where soft materials surfaces are fitted together or with hard material surfaces. The metric SS self tapping screws come in metric dimensions with sizes ranging from M6 through M160.
