Eye Bolt ZP

 Product Description

• Standard Name: Eye Bolt (Ring Bolt / Lifting Eye Bolt).

• Common Names: Lifting Eye Screw, Sheep Eye Bolt, Lifting Eye.

• Product Definition: A bolt featuring a circular or “D”-shaped ring head, designed for lifting, suspending, towing, or securing. ZP denotes a zinc-plated surface finish.

Eye Bolt ZP Key Features

• Zinc Plated (ZP) Coating: Provides basic rust protection and a bright silver finish, enhancing corrosion

  resistance, suitable for indoor or mildly damp environments.

• Eye Design: Forged closed eye at the top facilitates connection of ropes, chains, hooks, or lifting rings,

  providing a secure lifting point.

• Threaded Structure: The bolt features standard threads and is commonly used with nuts and washers;

  types include straight eye or shouldered eye.

• Material and Strength: Commonly made of carbon steel, offering medium strength; conforms to

  standards such as DIN 580 and ASME B18.15.

• Advantages: Convenient for lifting, economical and practical, easy to install, but the load must be

  axial to avoid side pulling.

Working Principle

• Threaded Fixing: The bolt is screwed into the base material or used with a nut, generating axial

  clamping force.

• Eye Connection: The closed eye provides a connection point, and ropes or hooks pass through the eye

  to transmit tensile force.

• Load Transmission: The tensile force is evenly distributed to the base material through the bolt; the zinc

  plating reduces friction and provides corrosion protection.

• Safety Control: Requires axial loading; avoid side pulling to prevent bending; the principle involves

  frictional gripping and mechanical wrapping.

Product Applications

• Lifting and Hoisting: Connecting chains or ropes for lifting equipment and structural components,

  providing temporary lifting points.

• Construction Engineering: Fixing railings, suspension rods, or curtain walls to concrete/wood.

• Mechanical Equipment: Fastening pipes, lighting fixtures, or brackets; zinc plating is suitable for

  indoor use.

• Home and DIY: Installing chandeliers, swings, or shelves; economical and practical.

• General Fixing: Any project requiring an eye connection.
