Product Description

The 201 Stainless Steel M4 Screws, M4 201 Stainless Bolts, and 201 Grade M4 Fasteners are corrosion-resistant components designed for secure fastening in demanding environments. Constructed from 201 stainless steel, these M4-sized fasteners feature a 4mm nominal diameter, with thread lengths and head styles customizable for diverse industrial applications such as construction, marine, chemical processing, and food-grade equipment. The material provides moderate resistance to oxidation and chloride exposure, suitable for temperatures between -20°C to 250°C. These fasteners typically utilize Phillips or hex drive interfaces, compatible with standard M4 nuts and threaded inserts. Key advantages include cost-effectiveness compared to 304/316 grades, high tensile strength (up to 515 MPa), and surface finish options like passivated or zinc-plated coatings. Limitations include reduced corrosion resistance in highly acidic or marine environments requiring higher-grade alloys. Installation torque ranges from 0.9-1.5 N·m depending on substrate material.
