Stainless Steel Snap Hook with Eyelet and Screw is a high-performance metal connector. The main body is forged with 304 or 316 stainless steel, which has both strength and corrosion resistance. Its structure includes a hook body with a spring, an eyelet at the tail, and a locking screw: the spring hook can be opened and closed quickly, the eyelet is convenient for threading ropes or connecting other accessories, and the screw provides secondary locking to prevent accidental falling off.
This accessory has a strong load-bearing capacity and is easy to operate. Press the spring to hook the hook and tighten the screw to fix it. The 304 model is suitable for general scenes such as outdoor and industrial. The 316 model is more suitable for strong corrosive environments such as marine and chemical industries due to its excellent salt spray resistance. It is widely used in mountaineering equipment, ship accessories, workshop fixation and other scenes that require safe and reliable connections.

Double safety guarantee: The spring automatically closes the hook mouth to form the first line of protection, and the tail screw manually locks the second insurance. The double mechanism completely eliminates accidental detachment caused by bumps and collisions, and is much safer than ordinary spring hooks in high-risk scenarios (such as mountaineering and hoisting).
Corrosion-resistant and durable material: Made of 304 or 316 stainless steel, the 304 model is resistant to daily moisture and rain corrosion, suitable for outdoor and industrial scenes; the 316 model contains molybdenum elements, which has stronger resistance to salt spray, acid and alkali, and can withstand long-term erosion from seawater and chemical environments. The service life is 3-5 times that of ordinary carbon steel hooks.
High strength and deformation resistance: The hook body is formed by forging and pressing, with high tensile strength (single hook load-bearing 100-500kg), not easy to bend or break when subjected to force, and can be adapted to temporary fixation of heavy goods or high-frequency pulling scenes.
Flexible connection and operation: The eyelet at the tail is compatible with a variety of accessories such as ropes, chains, bolts, etc. The hook mouth is adapted to circular fixing points, holes, etc. to achieve multi-scenario connection; pressing the spring baffle can quickly open and close, and the screw locking does not require tools, taking into account convenience and safety, and is suitable for frequent loading and unloading operations.
Stainless Steel Snap Hook with Eyelet and Screw is widely used in scenarios with high requirements for safety and environmental adaptability due to its characteristics of "double locking, corrosion resistance, toughness, and flexible connection":
Outdoor and extreme sports: Connecting safety belts and protection ropes during mountaineering, fixing rock point hanging pieces during rock climbing, double locking to prevent falling off; fixing diving equipment and surfboards, 316 material is resistant to seawater corrosion to ensure the safety of water sports.
Maritime and ship operations: Fixing life jackets on ship decks and connecting cables in sections to adapt to the turbulent environment of waves; connecting lifting rings and chains when hoisting cargo at the dock, and locking with screws to prevent cargo from shaking and causing unhooking.
Industrial and workshop maintenance: Fixing cables and air pipes in the workshop to prevent them from being dragged and loosened during equipment operation; temporarily fixing accessories for heavy machinery, the high strength of the hook body can withstand the continuous tension caused by equipment vibration.
Agriculture and outdoor facilities: Connecting brackets and windbreaks in greenhouses, resistant to wind and rain rust; fixing fences and feed barrel hangers in livestock farms to prevent livestock from falling off due to collisions and ensure breeding safety.
Warehousing and logistics assistance: Safety nets are connected to the edges of warehouse shelves to prevent goods from falling; during logistics turnover, pallet goods are fixed, ropes are passed through the eyelets and locked with hooks to adapt to bumpy truck transportation scenarios.
Q1: What should I do if the screw is stuck and cannot be turned after being locked?
It may be rusted due to long-term humidity, or the thread is slightly deformed after being stressed. You can first drop 1-2 drops of anti-rust lubricant (such as WD-40) and let it sit for 5-10 minutes to soak the thread; then use fine sandpaper to lightly grind the screw head to increase friction, and use a wrench to assist in twisting. If it still cannot be opened, do not force it (it may cause the hook to break). It is recommended to replace a new hook to avoid safety hazards.
Q3: A small gap appears at the hook mouth after bearing weight. Does it affect the use?
A small gap (≤0.5mm) may be normal elastic deformation. If it can be restored to its original state after unloading and there is no bending of the hook body, it can continue to be used but requires enhanced monitoring; if the gap exceeds 1mm, or is accompanied by local bulges and deformation of the hook body, it means that the metal structure has been damaged and the load-bearing capacity has decreased. It needs to be stopped and replaced immediately, especially in high-altitude operations and load-bearing scenes. Reuse is prohibited.
Q3: How to judge whether the wrong material (304 vs 316) is selected?
If used in marine, coastal or chemical environments, 304 material will rust in a short period of time (1-3 months), indicating that the material is not suitable and should be replaced with 316 (salt spray resistance is 2-3 times that of 304); in ordinary outdoor, workshop and other dry scenes, 304 rusts mostly because the surface is not cleaned in time after scratches, and the life can be extended by regular wiping and maintenance.
