Crosby M-279 Metric Shoulder Type Machinery Eye Bolts – Forged Steel – 200kg to 29.5t WLL

Description

The Crosby M-279 Metric Shoulder Type Machinery Eye Bolts are premium-quality lifting and rigging solutions designed for demanding industrial applications. Forged from quenched and tempered steel, these eye bolts combine exceptional strength with superior durability, ensuring reliable performance under in-line lifting conditions. Their metric threading allows easy integration into European and international machinery, frames, and lifting equipment.

Fatigue rated at 1.5 times the working load limit for 20,000 cycles, the M-279 eye bolts are built to withstand repeated lifting operations without compromise. They are engineered primarily for in-line pulls, providing optimum load distribution and safety during hoisting. While these eye bolts perform best in straight-line lifts, Crosby�s guidelines provide angle loading recommendations to ensure safe operation.

Every M-279 eye bolt is manufactured to meet or exceed the stringent requirements of ASME B30.26. This includes identification, ductility, design factor, proof load, and temperature specifications. Beyond these standards, Crosby ensures that all M-279 bolts also meet critical performance criteria not addressed in ASME B30.26, such as fatigue life, impact properties, and material traceability. This makes the M-279 eye bolt an industry-trusted component for high-stakes lifting applications where reliability and traceability are essential.

Available in a wide range of metric sizes�from M6 x 13 up to M64 x 127�these eye bolts offer working load limits from 200kg up to 29,500kg. This flexibility makes them suitable for light-duty applications, such as securing small machinery or components, through to heavy industrial lifting operations in manufacturing, construction, and rigging environments.

Crosby M-279 eye bolts are particularly valued in industries where adherence to safety standards and consistent performance under load is critical. Their robust forged steel construction and fatigue rating provide peace of mind for repeated use in lifting and hoisting scenarios.

Safety & User Instructions
Inspect eye bolt and threads before each use for signs of wear, deformation, or damage.
Never exceed the working load limit (WLL) specified for the bolt size.
Ensure correct alignment; use only for in-line pulls unless angle loading guidelines are applied.
Tighten eye bolts fully and secure into appropriately rated anchor points.
Avoid side-loading, bending, or torque that exceeds design limits.
Always follow ASME B30.26 safety standards and rigging best practices.
Use proper PPE and ensure personnel are clear of suspended loads during operation.
Replace any eye bolt showing cracks, elongation, or corrosion.
