Product Advantage
high-quality materials such as alloy steel and stainless steel are used, and after special heat treatment processes, the load-bearing capacity can reach 500kg-5 tons. Like the 304 stainless steel version, it has strong corrosion resistance and no obvious corrosion after salt spray testing for more than 48 hours, making it suitable for harsh environments.
Innovative spring lock structure, can be opened and closed with one hand, and the operation time is shortened to 3 seconds. Unique anti misoperation design, with a 60% increase in anti accidental disengagement force in the locked state, widely used in high-altitude operations, lifting equipment and other scenarios.
offering 12 different specifications including straight, S-shaped, and D-type, suitable for various connectors such as ropes, chains, and slings. It can be used in industrial lifting, outdoor equipment, safety protection, and other fields, meeting more than 90% of conventional connection needs.
Strictly following the ISO 9001 quality management system, each batch of products has passed 100000 opening and closing fatigue tests, with a defect rate of less than 0.3%, ensuring long-term stable use.
Support personalized customization, adjust parameters such as size, load-bearing capacity, and surface treatment according to customer needs, and produce samples within 72 hours to help customers create exclusive connection solutions.

Product Applications
Snap hooks are essential for climbing, hiking, and camping, providing secure connections for carabiners, ropes, and gear. Their lightweight yet high-strength design (up to 1,000 lbs load capacity) ensures safety during rock climbing or zip-lining. Many professional mountaineers rely on snap hooks for quick-release functionality in emergencies.
In warehousing, rigging, and construction, snap hooks are used for tool lanyards, safety harnesses, and load-securing. OSHA-compliant models feature double-lock mechanisms to prevent accidental openings, reducing workplace accidents. Their corrosion-resistant steel construction withstands harsh job site conditions.
Made from 316 stainless steel or galvanized materials, marine-grade snap hooks resist saltwater corrosion, making them ideal for boating, sailing, and diving. They securely fasten life jackets, anchor lines, and fishing gear, with tested durability in extreme wet environments.
Dog leashes, tie-out cables, and livestock tethers often use heavy-duty snap hooks for a secure yet quick-release connection. Their smooth spring mechanism allows easy one-handed operation, while reinforced gates prevent accidental detachment.
From keychains and backpacks to retail displays and gym equipment, snap hooks offer a versatile fastening solution. Their compact size and high load-bearing capacity (200-500 lbs) make them perfect for organizing tools, bags, and equipment at home or work.
1. Check Before Use
Inspect the snap hook for cracks, rust, or gate malfunctions. Ensure the load rating matches your needs. Never use a damaged hook – replace immediately.
2. Opening the Gate
Press the spring-loaded gate with your thumb while holding the hook body. For screw-lock models, twist the collar counterclockwise first.
3. Attaching the Hook
Slide the hook onto the desired anchor point (rope loop, D-ring, etc.). Ensure the connection is fully seated in the hook’s curve – not just on the gate.
4. Securing the Lock
For auto-locking hooks, release the gate to let it snap shut. For screw-lock types, twist the collar clockwise until tight. Always tug-test for security.
5. Regular Maintenance
Clean with a damp cloth after exposure to dirt/saltwater. Apply silicone lubricant to the hinge annually for smooth operation. Store in a dry place.
FAQ
A: Standard Snap Hook: Basic design with a simple spring gate.
Locking Snap Hook: Features a locking mechanism (screw gate, twist lock, or auto-lock) for added security.
Carabiner Snap Hook: Oval/D-shaped with a larger gate opening (common in climbing).
Heavy-Duty Snap Hook: Reinforced for high-load applications (e.g., rigging).
A:Standard: 50–500 lbs (varies by size/material).
Climbing-Grade: 20–30 kN (≈4,500–6,700 lbs).
Industrial: Check for ANSI/OSHA ratings (e.g., 5,000 lbs for fall protection).
A: Gate Function: Should close smoothly without sticking.
No Damage: Look for cracks, rust, or deformities.
Locking Mechanism: Test if it engages securely (if applicable).
A:Snap Hook: Smaller, often with a narrower gate (general-purpose).
Carabiner: Larger, stronger, and designed for climbing (meets UIAA/CE standards).
A:Clean dirt/debris with soapy water.
Lubricate the gate spring (silicone spray recommended).
Store dry to prevent rust.
Retire if damaged or after a severe fall (in climbing).
