Product Description

The M4.8x25-2# screws are high-precision M4.8 threaded fasteners belonging to the Metric 2# series bolts, designed for industrial applications such as machinery assembly, automotive components, and structural frameworks. With a 4.8mm diameter and 25mm length, these galvanized steel bolts offer a tensile strength of 8.8 grade, operating effectively within a temperature range of -30°C to 120°C. Their corrosion-resistant coating ensures durability in harsh environments, while the standardized thread pitch guarantees compatibility with M4.8 nuts and pre-tapped holes. Key advantages include reliable mechanical stability, ease of installation with standard hex keys, and resistance to vibration loosening. Limitations include a narrow suitability for non-ferrous materials and potential threading challenges in hardened surfaces. Ideal for securing medium-load components in manufacturing and engineering systems.
