Product Description

The Hex flange screws M5x25, also known as M5x25 hex flange bolts, are metric flange screws designed for secure fastening in industrial machinery, automotive assemblies, and electronic enclosures. These screws feature a hexagonal head with an integrated flange for load distribution, eliminating the need for separate washers. With a thread size of M5 (5mm diameter) and a length of 25mm, they provide robust mechanical stability in environments operating between -30°C to +120°C. Constructed from high-grade steel with optional corrosion-resistant coatings, they are ideal for high-vibration applications. Their flanged design enhances grip strength and reduces loosening under stress. Metric flange screws M5x25 are widely used in sectors requiring precise metric fasteners, offering easy installation with standard tools but may require torque calibration for optimal performance. Key variants include M5x25 hex flange bolts and Hex flange screws M5x25.
