Product Overview

The 1.5" 35mm 3000kg Double J Zinc Plated Wire Hook is a metal connection fitting designed for compatible cargo lashing, tie-down strap assemblies, and industrial fastening applications.

Its double J-shaped profile provides a hook-style connection point for compatible anchor points, rings, or lashing hardware. The zinc-plated surface helps protect the underlying steel against corrosion under suitable service conditions.

With a nominal size of 1.5 inches (approximately 38.1 mm) and a listed 35 mm specification, this product is intended for applications where hook geometry and connection compatibility are important. Because these dimensions may refer to different parts of the hook, the exact dimensional drawing should be confirmed before ordering.

The stated 3000 kg capacity must be verified against the manufacturer's specification to determine whether it refers to lashing capacity (LC), breaking strength, or another rated value. These ratings are not interchangeable.

For cargo lashing manufacturers, ratchet strap producers, rigging hardware distributors, and industrial buyers, the hook can be specified according to strap width, mounting requirements, finish, and order quantity.

Product Features

1. Double J-Shaped Hook Design

The double J profile provides a curved connection structure for compatible cargo restraint systems.

Depending on the exact design, the hook can engage with suitable anchor points and lashing rings. Buyers should verify the opening dimensions and hook geometry against the intended connection point.

2. Zinc-Plated Surface

The zinc-plated finish helps reduce corrosion of the steel surface during storage, transportation, and normal use.

Corrosion resistance depends on the plating specification, coating thickness, surface condition, and operating environment. Additional protection may be required for prolonged exposure to moisture, salt, or corrosive chemicals.

3. 35mm Specification

The 35 mm dimension may relate to the hook opening, width, or another defined measurement. The product drawing should specify the measurement reference.

This is especially important when matching the hook with cargo lashing straps, anchor points, or existing hardware.

4. Listed 3000kg Capacity

The product title specifies a 3000 kg capacity. Before use, confirm the exact rating and its definition on the technical datasheet or product marking.

For cargo restraint applications, lashing capacity (LC) and breaking strength represent different values. A 3000 kg breaking strength must not be treated as a 3000 kg lashing capacity.

5. Suitable for Lashing Hardware Assemblies

The hook may be incorporated into compatible cargo tie-down or lashing strap assemblies, subject to its design and rating.

The finished assembly's rated capacity depends on the hook, strap, stitching, adjustment hardware, termination method, and applicable requirements.

Technical Specifications

Important: Do not publish the 3000 kg figure as a confirmed LC unless the manufacturer has documented that exact rating for the model. For cargo restraint products, the complete assembly and its markings must be checked before use.

Product Advantages

Applications

1. Ratchet Tie-Down Straps

Double J hooks may be used as end fittings for suitable ratchet tie-down straps, provided the hook profile and rating match the strap assembly.

2. Cargo Securing

Compatible hooks can connect lashing straps to suitable anchor points when securing cargo during road transportation and material handling.

3. Truck and Trailer Lashing

The hook may be used in appropriate truck or trailer restraint systems. Confirm that the hook fits the vehicle's anchor points and meets the relevant cargo-securing requirements.

4. Industrial Transport

For machinery, equipment, and packaged goods, compatible lashing hardware can help secure loads during transportation.

5. Lashing Strap Manufacturing

Manufacturers of cargo tie-down straps may source zinc-plated double J hooks for integration into specified webbing assemblies.

This product should not be assumed suitable for overhead lifting. Cargo tie-down hooks and lifting hooks serve different functions unless a product is specifically designed and rated for lifting.

How to Choose the Right Double J Wire Hook

1. Confirm the Strap Width

Check the width of the webbing or strap assembly and confirm that the hook's attachment section is compatible.

2. Verify the Hook Dimensions

Confirm the 35 mm specification, overall length, opening width, wire diameter, and attachment geometry using a dimensioned drawing.

3. Identify the Required Capacity

Confirm whether 3000 kg refers to LC, breaking strength, or another manufacturer-defined rating. Do not compare these values as though they are equivalent.

4. Check the Anchor Point

The hook must engage securely with the intended lashing point without unsuitable contact, excessive movement, or risk of disengagement.

5. Select the Surface Finish

Zinc plating may be suitable for many general cargo-restraint applications. For corrosive environments, check the plating specification and expected service conditions.

6. Confirm Applicable Standards

For commercial cargo restraint systems, specify any required standard, marking, testing, or documentation before ordering.

Double J Hook vs. Single J Hook

The choice should be based on the actual anchor-point design, strap configuration, and verified rating rather than the hook name alone.

Manufacturing Process

Step 1: Material Selection

Steel material is selected according to the product design and specified mechanical requirements.

Step 2: Forming

The metal is formed into the required double J hook profile using suitable production equipment.

Step 3: Shaping and Finishing

The hook geometry is finished, with attention to the connection profile, attachment section, and surface condition.

Step 4: Zinc Plating

The hook receives the specified zinc-plated finish to help protect against corrosion.

Step 5: Dimensional Inspection

Critical dimensions are checked against the approved drawing, including the hook opening and attachment section.

Step 6: Rating Verification and Testing

Where applicable, testing and inspection are conducted according to the relevant product specification and standard. The capacity marking must match the verified rating.

Step 7: Packaging

Products are packed in bulk cartons or customized packaging according to order requirements.

Safety and Inspection Considerations

• Inspect the hook for cracks, deformation, excessive wear, or damaged plating.

• Confirm that the hook engages securely with the intended anchor point.

• Check that the hook is compatible with the strap width and attachment method.

• Verify whether the stated 3000 kg value is LC or breaking strength.

• Never exceed the rated capacity of the complete lashing assembly.

• Do not use cargo lashing hardware for overhead lifting unless specifically designed and rated for that purpose.

• Avoid shock loading and unsuitable side loading.

• Follow the applicable cargo-securing regulations and manufacturer's instructions.

• Replace damaged hooks rather than attempting unauthorized welding, heating, or reshaping.

Factory Direct Supply and OEM Customization

For an accurate quotation, provide the product drawing, required dimensions, strap width, material specification, finish, required rating and its definition, quantity, and applicable standard.

FAQ

1. What is a double J zinc-plated wire hook used for?

It is commonly used as a connection fitting in compatible cargo lashing and tie-down strap assemblies. The exact application depends on the hook design and verified rating.

2. Does 3000 kg mean the hook's lashing capacity?

Not necessarily. The figure may refer to lashing capacity, breaking strength, or another specification. Confirm the manufacturer's datasheet and product marking before use.

3. What does 35 mm refer to?

It depends on the manufacturer's dimensional definition. It may refer to the hook opening, width, or another dimension. Request a drawing before ordering.

4. Is zinc plating suitable for outdoor use?

Zinc plating can provide corrosion protection in suitable environments. Its performance depends on the plating process, coating thickness, and exposure conditions.

5. Can the double J hook be used for lifting?

Do not assume it is suitable for overhead lifting. Cargo lashing hardware is intended for load restraint, not automatically for suspending loads. Use only products specifically designed and rated for the intended lifting application.

6. Can you supply double J hooks for bulk orders?

Bulk supply and OEM requirements can be discussed according to the requested dimensions, material, finish, rating, quantity, and packaging.
