Product Description

The M4x12x9 Screw is a precision M4 Threaded Fastener with a 12mm shank length and 9mm hex socket head, compliant with DIN 912 standards. Designed for secure fastening in industrial assemblies, this hex socket bolt features a 4mm hexagonal drive requiring a matching Allen key for installation. Manufactured from grade 12.9 alloy steel, it withstands tensile strengths up to 1220 MPa and operates effectively across temperatures from -50°C to +150°C. The full M4 thread profile ensures reliable engagement with mating components in automotive, machinery, and electronic equipment applications. Its compact DIN 912-compliant low-profile head enables space-constrained installations while maintaining high torque capacity. Key advantages include excellent corrosion resistance with optional coatings, vibration-resistant thread retention, and superior mechanical durability under high-stress conditions. Potential limitations include requirement for precise installation tools and unsuitability for non-metallic substrates without reinforcement.
