Product Description

The M5x40 Screw is a high-precision M5x40 Hex Bolt engineered as a durable M5x40 Metric Fastener for industrial assembly and machinery. This corrosion-resistant fastener features a 40mm shaft length, 5mm diameter, and hex head design for secure torque application. Operating reliably in temperatures from -30°C to 120°C, it is commonly used in automotive, manufacturing, and robotics sectors. The hardened steel construction ensures superior tensile strength (8.8 grade) and vibration resistance, though improper installation may risk thread stripping. While lacking integrated electronics, its standardized metric sizing enables seamless compatibility with ISO-certified components. Ideal for structural joints requiring precision alignment, it replaces bulkier fasteners while maintaining mechanical stability under dynamic loads.
