As a core lifting component under Japan’s MARTEC, the FRENO eye bolt stands out thanks to its high‑strength materials, versatile size options, and flexible installation design, making it the preferred choice for heavy‑industry applications such as aerospace, wind energy, automotive manufacturing, and port logistics. With its hallmark advantage of “small threaded holes supporting substantial loads,” it addresses the longstanding challenges of cumbersome traditional eye‑bolt installations and limited load capacity, thereby establishing a robust safety foundation for lifting operations involving heavy objects. Below is a detailed product overview:
Core product series, tailored to diverse lifting applications. Mattek’s eye bolts are primarily available in three major series—A, B, and C—each engineered with differentiated designs to meet varying installation requirements and load‑bearing standards. They cover a broad working load range from 0.3 t to 20 t, with bolt diameters ranging from M8 to M100, ensuring comprehensive compatibility across a wide array of industrial lifting scenarios. Specific parameters and features are as follows:
FRENO Eye Bolt Type A, High-Strength Compact Model
Core Features: With the same screw diameter, its load‑carrying capacity is three times that of a standard JIS bolt with a washer, allowing for smaller tapped holes in the workpiece, simplifying the machining process, and increasing flexibility in installation positioning. Models marked with “S” feature built‑in bearings, making them suitable for high‑precision operations such as reversing or erecting the workpiece.
Applicable scenarios: Scenarios with stringent requirements for installation space and operational accuracy, such as mold assembly, hoisting of precision machine tools, and lifting of small mechanical equipment.
Key specifications: Load capacity: 0.3 t – 15 t; screw diameter: M8 – M48; for example, model A‑48L has a load capacity of 15 t and is suitable for complex overturning and lifting operations.
FRENO Eye Bolt Type B JIS – Compatible with Eye Bolts
Core Features: It offers the same strength as JIS eye‑bolt fasteners of the same thread diameter and can be directly fitted into the existing tapped holes designed for eye bolts, eliminating the need for additional hole modifications while ensuring both safety and compatibility.
Applicable scenarios: Required for retrofitting aging equipment that replaces traditional JIS‑standard lifting rings, as well as for general mechanical lifting applications.
Key specifications: Load capacity: 0.95 t to 20 t; screw diameter: M24 to M100. The top-of-the-line MB series models offer a load capacity of up to 20 t, making them suitable for lifting heavy-duty equipment.
FRENO C-Shape Welded Eye Bolt
Core Features: There is no need to tap threads in the workpiece; it can be directly welded and secured, eliminating the repetitive tasks of installation and removal and improving operational efficiency.
Applicable scenarios: Scenarios such as large steel structures, ship sections, and heavy workpieces that cannot be drilled.
Key specifications: Base model C‑10 with a load capacity of 0.5 t, and C‑16 with a load capacity of 1.6 t, suitable for lifting small to medium-sized welded workpieces.
Rigorous quality and craftsmanship, building a robust safety barrier for lifting operations.
High‑strength material assurance: The entire product line is forged from premium alloy steel, offering both exceptional toughness and fatigue resistance. It can withstand impact loads and sustained tensile forces during lifting operations, effectively preventing safety hazards such as fracture and deformation at the source.
Detailed design enhances safety: Certain models are equipped with precision torque‑adjustment standards—e.g., the A‑8 model offers a torque range of 8–15 Nm, ensuring secure and reliable fastening. Models featuring bearings provide smooth rotation, minimizing torsional stress during lifting and reducing damage to lifting hardware and workpieces, while also accommodating complex angle‑adjustment requirements.
Adaptable to multiple operational scenarios: It can accommodate various lifting angles, including vertical and side‑pull configurations, and, when used with lifting equipment, enables 360° horizontal rotation and multi‑angle hoisting. Even in confined spaces or when handling irregularly shaped workpieces, it allows for flexible posture adjustments, ensuring stable and reliable operations.
Broadly adaptable across industries, empowering efficient production operations.
With its reliable load-bearing performance and versatile installation options, Mattek’s eye bolts have been extensively adopted across numerous key industrial sectors:
In the wind power industry, it facilitates the precise alignment and assembly of wind turbine blades.
In the automotive industry, warehousing and lifting operations are performed for components such as chassis and transmissions.
In the port and shipping sectors, it ensures the efficient execution of heavy‑duty operations such as ship section assembly.
It is also suitable for specialized operations such as underground equipment installation in coal mines and the lifting of precast concrete components, comprehensively meeting the safety and efficiency requirements of diverse industries.
