Shoulder screws, also referred to as shoulder bolts, are essential fasteners designed to ensure secure spacing, smooth motion, and rotational functionality.
Basic Knowledge: Stainless steel is an alloy material with corrosion resistance, composed primarily of iron, chromium, and nickel. These elements resist oxidation and corrosion, providing durability and aesthetic appeal.

201, 304, 316 are austenitic stainless steels, typically non-magnetic. Weak magnetism may occur due to composition segregation or improper heat treatment. Corrosion resistance comes from chromium oxide protective layers. At 450°C-900°C, chromium carbide formation at grain boundaries can reduce corrosion resistance ("intergranular corrosion"). Low-carbon variants (304L, 316L) minimize this effect, especially important in highly chlorinated environments.
304 is a general-purpose stainless steel widely used for equipment requiring good corrosion resistance and formability. It contains ≥18% chromium and ≥8% nickel, meeting ASTM standards. In fastener industries, 302HQ and 304 are often called A2, while 316/316L are called A4.
