Product Description

Stainless Steel Machine Screws Bi Metal Screw Self Tapping /Self Drilling Screw Product Description
Self-tapping Screw, also known as self-tapping nail, is a kind of threaded nail with self-tapping and locking functions. It can tap and drill out the matching female thread in metal or non-metal materials by itself without the need to pre-tap the threaded hole, greatly improving the installation efficiency.
Materials
Carbon Steel: It is a commonly used material with high strength and good toughness. After carburizing treatment, it has high surface hardness and strong wear resistance. Stainless Steel: It has good anti-rust performance and is suitable for humid or corrosive environments. Common ones include SS304, SS316, etc. Titanium and Titanium Alloys: They have extremely high strength, good corrosion resistance and biocompatibility, and are often used in special fields such as aerospace and medical devices. Other Materials: Including plastic self-tapping screws, which have low cost, light weight and corrosion resistance, and are used in occasions with low strength requirements; wooden self-tapping screws are used for wood connection, with poor strength and durability.
Types
There are round heads (semi-round heads), flat round heads, round head flanges (with washers), flat round head flanges (with washers), pan heads, pan head flanges (with washers), countersunk heads, oval countersunk heads, cylindrical heads, hexagonal heads, hexagonal flange heads, hexagonal flanges (with washers), etc
Product Parameters

Dimensions	Diameter: Self-tapping screws come in a variety of diameter specifications. Commonly seen nominal sizes include T1.2, T1.4, T1.6, T1.7, T2.0, etc., with corresponding different ranges of outer diameters and inner diameters1. Length: There are diverse length specifications. For example, the length of a self-tapping screw with a nominal size of T1.2 is 2.5 - 6 mm, and that of T2.0 is 3 - 15 mm1.
Thread	Threads per Inch: The common levels of the number of threads per inch in length are 14, 16, and 242. Thread Types: This includes self-tapping threads (coarse threads), machine threads (ordinary threads), drywall screw threads, fiberboard screw threads, etc. In addition, there are also various forms such as single lead (single start), double lead (double start), multiple lead (multi-start), and high-low double-start threads.
Surface Treatment	To enhance the corrosion resistance and service life of self-tapping screws, their surfaces are usually subjected to electroplating, phosphating, and other treatments.
