Product Description

The metric hex bolts M5x30, also known as M5-30 external hex screws or M5x30 metric hex cap screws, are standardized fasteners designed for high-strength mechanical assembly. These bolts feature a 5mm diameter, 30mm length, and ISO metric thread pitch, compatible with standard M5 nuts. Constructed from grade 8.8 carbon steel or corrosion-resistant A2/A4 stainless steel, they operate reliably in temperatures from -50°C to 300°C. The external hexagonal head enables secure torque application up to 8 Nm using 8mm wrenches. Widely used in automotive, machinery, and construction industries, these screws provide robust clamping force for structural joints, equipment frames, and heavy-duty fixtures. Key advantages include precise dimensional compliance, vibration resistance, and easy installation, though they require proper sealing in corrosive environments. Surface treatments like zinc plating or galvanization enhance durability in harsh conditions.
