EJ7047 by Beckhoff

The Beckhoff EJ7047 bolt is a robust industrial fastener from the EJ EtherCAT Plugins series, engineered for demanding automation environments. Constructed of stainless steel with a zinc plated finish, this component delivers reliable strength and corrosion protection for machinery and control cabinets. Featuring a hexagonal head profile, it permits quick assembly and disassembly with standard tools. The design emphasizes compatibility with industrial-grade equipment, ensuring stable connections in dynamic applications. With a focus on durability, the EJ7047 meets the stringent quality benchmarks set by Beckhoff.

This fastener provides a comprehensive set of technical specifications tailored for high-stress conditions. The bolt’s thread size of M10 x 1.5 facilitates secure mating with corresponding tapped holes or nuts. It boasts a tensile strength rating of 800 MPa, confirming its ability to withstand substantial axial loads without deformation. The overall length of 47 mm and a drive size of 17 mm ensure proper engagement depth and efficient torque application. Manufactured to the ISO 4017 standard, this part maintains consistent geometry and performance across production batches.

Operational performance is assured through a wide operating temperature range from -40 degrees C to 200 degrees C, enabling continuous service in both subzero and high-heat environments. High corrosion resistance derived from the stainless steel substrate and zinc plating protects against oxidation, chemical exposure, and moisture ingress. The hex head type design reduces the risk of tool slippage under high torque, improving safety during maintenance operations. Its compact form factor and balanced mass distribution minimize vibration-induced loosening in high-cycle applications. Together, these features deliver dependable performance in factory automation and process control systems.

System integration is streamlined by the EJ7047’s adherence to established industrial standards, making it suitable for use in electrical enclosures, conveyor assemblies, and EtherCAT-based distributed I/O modules. Its compatibility with Beckhoff’s modular architecture simplifies upgrade and retrofit projects, reducing implementation time. Target applications include panel building, robotic end-of-arm tooling, and mechanical fixtures in automated production lines. The EJ7047 fastener serves as a foundational element for secure, long-lasting connections in modern industrial automation solutions.
