We are able to provide clevis slip hooks in all sizes in the form. In addition to that, we also provide OEM service, and the engineers will make a perfect solution according to your drawings and give a more reasonable quotation.

Clevis Slip Hooks Details

We offer Clevis Slip Hooks in 1/4" to 3/4" Sizes, the exact sizes are reflected in the table above. We use high-performance carbon steel or alloy steel to produce Clevis Slip Hooks, which gives it two properties. Here you can learn more about Clevis Slip Hooks.

What is Clevis Slip Hooks

This is a hook used to connect the end of a chain and a heavy object (a heavy object with a hook point such as a chain, wire rope, lifting clutch, etc.). It is also called a Sling Hook most of the time. The inner circle of the hook is round and the inner cavity is large. The chain can slide easily in the inner cavity to adjust the length. It is mainly made of carbon steel and alloy steel, using hot die forging technology, with a stable structure and stronger tensile performance. There are two styles to choose from, depending on whether it has a latch.

It consists of clevis ear, hook body, clevis pin, safety pins, and optionally safety latch.
Note: The Clevis Ear and Hook Body are forged from one piece.

Clevis Ear:

Shaped like a clip, it is used to snap into the end of the chain and has two round holes in it.

Clevis Pin:

It is a through hole at one end and a thicker end at the other end, which is used to carry the axial shear load in the whole system.

Safety Pins:

The hole used to insert the clevis pin is used to prevent it from coming out.

Hook Body：

It is a hook-shaped structure with a rounded inside, which can facilitate the load to better enter the load.

Safety Latch:

It is a self-rebounding device where the hook snaps into the spreader and the latch springs back to prevent decoupling.

The Types of Clevis Slip Hooks

It can be classified according to strength, material, whether it has safety latch or not, surface treatment, etc. They are functionally identical, differing in WLL, appearance, and corrosion resistance. If you want to know more, you can contact us to get it.

How it work：

Step 1:

We need to remove the Safety Pins and Clevis Pins (if they are already pre-installed on the Clevis Slip Hooks).

Step 2:

We need to snap the Clevis Ear into the end of the chain.

Step 3:

We need to insert the Clevis Pin into the hole of the Clevis Ear and the Safety Pin into the hole of the Clevis Pin, and we complete the lock of the Clevis Slip Hooks and the chain.

Step 4:

The hooks are hooked onto the chain or other object of the load, and the tension machine slowly applies the tension force to balance the entire structure to prevent uncoupling.

Production of Clevis Slip Hooks:

We often need to go through 10 steps to complete the order of Clevis Slip Hooks, and the 11th step is our after-sales service. Because each customer's needs are different, we will tailor the solution according to the needs.

1. Order Planning & Scheduling

Upon receiving your Clevis Slip Hooks order, our production planners swiftly evaluate volume and delivery expectations. We allocate capacity on our forging lines more efficiently than most competitors, enabling earlier start dates and minimizing lead times. By integrating order details with our ERP system, we dynamically optimize schedules—so your project advances more predictably and flexibly.

2. Raw Material Procurement & Inspection

We source high-performance carbon or alloy steel from vetted suppliers under long-term contracts, securing more favorable pricing and traceability. Incoming steel bars undergo photometric composition analysis and ultrasonic testing to verify chemical and structural integrity. This rigorous screening is more thorough than industry norms, guaranteeing every Clevis Slip Hook begins with consistently reliable material.

3. Mold Installation & Trial Runs

Our skilled technicians install the precise forging dies for G60, G70, or G80 grade hooks, then perform dry runs to confirm geometry and alignment. These pre-production trials reduce die wear and scrap rates, and ensure each hook's clevis ear and hook body are forged proportionally. Fine-tuning during this phase leads to more uniform hook profiles and less rework downstream.

4. Cutting to Length

Automatic bar-cutting machines slice steel rods into blanks with tighter tolerances than manual sawing. By employing high-speed automatic feeders, we achieve more consistent blank lengths and reduce material waste. Precise cut lengths are crucial for balanced heating and forging, setting the foundation for consistent hook dimensions.

5. Induction Heating of Blanks

Forging blanks are heated in advanced electromagnetic induction furnaces that reach forging temperature faster and more evenly than conventional methods. This uniform heating helps produce more refined grain structures in the steel, resulting in Clevis Slip Hooks with higher fatigue resistance and more predictable mechanical performance.

6. Closed-Die Forging

Heated blanks are formed into clevis ear and hook body in a single pressing operation using our fully hydraulic forging presses. This integrated approach yields hooks that are more compact and have superior grain continuity compared to multi-stage processes. Experienced operators monitor forging loads to ensure each part achieves complete die fill without excessive flash.

7. Semi-Finished Inspection

Immediately after forging, hooks undergo preliminary dimensional checks using optical comparators and hardness testing to screen out any deviations. This early inspection step is more proactive than standard practice: any non-conforming blanks are recycled before entering machining, reducing overall rework and enhancing throughput.

8. Machining & Surface Preparation

Flash is removed by precision milling, then hooks pass through shot-blasting and de-burring stations to attain a smoother surface. Finally, parts are prepared for plating or powder coating. Our multi-stage surface prep achieves more uniform adhesion and a finer finish than single-step processes, laying the groundwork for durable corrosion protection.

9. Final Quality Inspection & Packaging

Finished hooks are validated against your specifications through a comprehensive ISO 9001-aligned audit: two-times safety-factor tensile tests simulate working loads, while four-times loads ensure break strength. Salt-spray chambers evaluate corrosion endurance. Upon approval, each batch is serialized, labeled, and packaged in reinforced cartons that protect components better than standard packaging.

10. After-Sales Support

Beyond delivery, our dedicated after-sales team stands ready to address any quality or quantity concerns. With faster response times than typical service centers, we initiate return, replacement, or replenishment procedures within 24 hours of your notification. This commitment makes our post-delivery care more reliable and more customer-centric.
