The double spring hook JY027 is a high-performance plastic snap hook engineered for secure mounting, load-bearing connection, and rapid one-click operation. Built from POM (polyoxymethylene) — a material known for high rigidity, low friction, and excellent chemical resistance — this hook delivers consistent performance in both outdoor and industrial environments.
At Annaifu, we specialize in plastic buckle and hook development for bags, outdoor gear, sports equipment, safety harnesses, and more. The JY027 is one of our core snap hook solutions, available for OEM/ODM customization, bulk wholesale orders, and factory-direct supply.

The dual-spring structure enables one-click open and close operation. Both springs work in parallel to distribute tension evenly, reducing wear and extending service life. This design is particularly valuable in scenarios requiring frequent attachment and detachment — tool belts, equipment rigging, and gear loops.
POM plastic offers a superior strength-to-weight ratio compared to standard nylon or ABS. The JY027 resists deformation under sustained load, making it suitable for load-bearing applications where structural integrity is critical. It does not become brittle under moderate cold and maintains dimensional stability across temperature ranges.
The hook body undergoes a dedicated rust-prevention surface treatment. This makes the JY027 suitable for outdoor environments — rain, humidity, salt air — without the corrosion risk associated with untreated metal hooks. Service life is extended significantly compared to standard metal alternatives.
Despite its load-bearing capacity, the POM body keeps the total hook weight minimal. This matters for end-use products like backpacks, climbing gear, and harnesses where cumulative component weight directly impacts user comfort.
The arc-shaped hook body is designed for ergonomic single-hand use. The buckle seats flush against the hook body during closure, eliminating play or rattle under load.
Item Mounting: Connect and fix different items for portable storage
Quick Release: Dual spring structure supports one-click opening and closing with efficient, stable operation
Load Bearing: High-strength POM material carries a defined weight range without deformation or failure
Corrosion Resistance: Suitable for prolonged outdoor use in wet, humid, or chemically active environments
The JY027 double spring hook is used across a wide range of industries and product types:
Outdoor & Sporting Goods Camping gear, hiking packs, climbing accessories, bicycle panniers, hydration systems, tent attachment points. The rust-proof finish and high load rating make it a direct fit for gear that faces weather stress.
Bags & Luggage Backpack accessory loops, side-release connection points, luggage ID tag attachment, suitcase handle hardware. Compatible with webbing widths common in bag manufacturing.
Industrial & Workplace Temporary tool hanging in workshops and warehouses, equipment tethering on scaffolding, parts organization in assembly lines. The rapid-release mechanism reduces time spent on attachment tasks.
Daily Carry & Fashion Accessories Key rings, bag charms, lanyard terminals, ID badge clips, and compact daily-carry hooks. The smooth POM surface and clean arc form factor suit consumer product aesthetics.
Safety & Rescue Equipment Harness connection points, rescue line attachment, first-responder gear loops. Load-bearing POM with double-spring locking reduces unintended release risk.

The JY027 consists of:
Arc-shaped hook body – POM molded, ergonomic curvature for hand grip and load distribution
Double spring gate assembly – Two independent springs drive the gate, providing redundant closure force
Rust-prevention surface layer – Applied to the hook body exterior for environmental resistance
Flush-close buckle gate – Seats tightly against the hook body under load; no gap or rattle
Annaifu offers factory-direct customization for the JY027 and all spring hook models:
Material selection: POM, nylon, ABS, recycled GRS-certified plastics
Color: Full Pantone color matching
Logo integration: Laser engraving or in-mold injection molding
Dimension modification: Custom sizing for specific webbing or load requirements
Special properties: Anti-slip texture, low-temperature resistance, UV stabilization
Minimum order quantities and lead times are flexible. Standard proofing is completed within 2–3 weeks; VIP channels can compress this to 72 hours for strategic partners.

Q: What is the load capacity of the JY027 double spring hook?
A: The JY027 is rated for high load-bearing applications using POM material. Exact load specifications depend on end-use configuration. Contact our technical team for load test data relevant to your application.
Q: Can the double spring hook be used in cold weather outdoor environments?
A: POM maintains structural integrity across a moderate cold range. For extreme low-temperature applications (below -20°C), we recommend specifying our cold-resistant plastic formulation.
Q: Is custom LOGO engraving available on the JY027?
A: Yes. We support laser engraving and in-mold injection molding for LOGO integration. Engraved logos pass 5,000-cycle friction tests under standard use conditions.
Q: What is the minimum order quantity for wholesale or OEM orders?
A: Standard MOQ is 5,000 pieces per batch. Flexible production lines support smaller replenishment runs for established accounts. Contact us for volume pricing.
Q: How long does custom development take?
A: Standard development (mold design → proofing → testing) takes 2–3 weeks. Priority production channels are available for strategic customers.
Q: Does the JY027 meet environmental standards?
A: Yes. Our products comply with OEKO-TEX Standard 100 and GRS recycled material certifications are available on request. Third-party test reports can be provided.
