Product Description

The M3.5x50mm stainless steel screw, also designated as M3.5x50-2# galvanized bolt or M3.5x50 high-tensile screw, is a precision fastener engineered for robust industrial applications across construction, automotive, and machinery sectors. Crafted from corrosion-resistant stainless steel or zinc-plated carbon steel, it features a 3.5mm diameter and 50mm length with a #2 drive head for high torque compatibility. This screw operates reliably in temperatures ranging from -40°C to 120°C and withstands vibration-heavy environments. Its high-tensile strength (up to 8.8-grade) ensures structural integrity under extreme mechanical stress, while the galvanized variant offers enhanced rust protection for outdoor use. Common applications include securing electrical panels, HVAC systems, and heavy equipment assemblies. Key advantages include durability, chemical resistance, and dual-material versatility, though its specialized design may require specific installation tools.
