Understanding the Main Types of Eye Bolts<\/h2>\n\n\n\n
\"Understanding<\/figure>\n\n\n\n

Selecting the correct type of \u0440\u044b\u043c-\u0431\u043e\u043b\u0442<\/a> is not a matter of preference; it is a fundamental requirement for operational safety and efficiency. Different designs serve distinct purposes, and understanding their capabilities is the first step in proper rigging. Each type possesses unique characteristics tailored for specific load conditions and applications.<\/p>\n\n\n\n

Shouldered Eye Bolts<\/h3>\n\n\n\n

Design for Angular Loads<\/h4>\n\n\n\n

Shouldered eye bolts feature an integrated collar or “shoulder” between the eye and the threads. Designers create this shoulder to brace the bolt against the load-bearing surface. This design element provides critical support against bending forces, making these eye bolts suitable for angular or off-axis loading. The shoulder effectively transfers the shear stress from the shank to the surface it is mounted on.<\/p>\n\n\n\n

Any gap between the shoulder and the surface will negate its ability to resist bending forces and can lead to catastrophic failure.<\/p>\n<\/blockquote>\n\n\n\n

Applications in Rigging and Lifting<\/h4>\n\n\n\n

These eye bolts are the workhorses of professional rigging applications. Their ability to handle angular pulls makes them indispensable for complex lifts where a perfectly vertical pull is not possible. Riggers use them to connect slings, shackles, and other lifting hardware for hoisting structural components, precast concrete panels, and heavy materials.<\/p>\n\n\n\n

The load capacity of shouldered eye bolts decreases significantly as the pull angle increases from vertical. The table below illustrates the rated capacities<\/a> for standard and alloy steel shouldered eye bolts at both vertical (0\u00b0) and 45\u00b0 angles.<\/p>\n\n\n\n

Plain (Non-Shouldered) Eye Bolts<\/h3>\n\n\n\n

Design for In-Line Vertical Loads<\/h4>\n\n\n\n

Plain eye bolts, also known as non-shouldered or “plain pattern” eye bolts<\/a>, lack the supportive collar found on shouldered models. Their construction is simple: a threaded shank directly connected to the eye. This design offers no resistance to bending or shear forces. Therefore, their use is strictly limited to in-line, vertical lifts<\/a> where the pulling force is perfectly aligned with the shank. Any side loading will bend the bolt and compromise its integrity.<\/p>\n\n\n\n

Use Cases for Straight-Line Pulls<\/h4>\n\n\n\n

Plain eye bolts are not intended for heavy-duty overhead lifting in professional construction. Instead, they serve lighter-duty functions where only a straight pull is required. Common use cases<\/a> \u0432\u043a\u043b\u044e\u0447\u0430\u044e\u0442:<\/p>\n\n\n\n
