Product name: Hexagon socket set screws

Implementation standard: American standard ASME B 18.3 - 2003 (Table 5)

Product Overview: Hexagon socket tip set screws are also called pointed tail machine screws, hexagon socket cone-end headless screws, top screws, and positioning screws. Pointed tail top screws are usually used on contact surfaces with lower strength, effectively playing the role of positioning and preventing loosening. Hexagon socket tip set screws are classified according to standards: DIN 914 German standard hexagon socket tip tail machine screws, national standard GB 78 cone-end headless screws, international standard ISO 4027 cone-end top screws, Italian standard UNI 5927 tip positioning screws.

Material classification: Usually made of alloy steel, stainless steel, copper and other materials. Different materials are used in different environments. Alloy steel is normally used to make 12.9 grade high-strength hexagon socket pointed set screws, and stainless steel set screws are normally used in environments that require environmental protection, corrosion resistance and oxidation resistance, such as food machinery, medical machinery, etc.

Product materials: SUS304, SUS316, SUS316L, 410 and other stainless steel special materials, carbon steel (1008, 1022, 10B21, 35K, 45K), alloy steel (10B33, 40Cr, SCM435), B7, B7M, A320 L7/L7M, etc.

Product grade: A2-50, A2-70, A4-70, A4-80, B8, US grade 2, US grade 5, US grade 8, US grade 10, grade 12.9, etc.
