What are Hooks?
Hooks are simple curved fasteners used to hang, suspend, or connect items without permanent hardware. In this category you’ll typically see S hooks, which are shaped like the letter S. They clip into chain, wire shelving, eyelets, or rope and are popular for organizing tools, hanging signs, or suspending light fixtures and parts.
Open vs Closed S Hooks
Open S hooks have gaps at each end so you can attach and remove them quickly. They’re handy for temporary setups and easy repositioning.
Closed S hooks are squeezed shut with pliers after installation. Closing the ends helps keep chain or rope from slipping out and adds security where vibration or movement is likely.
How to Choose S Hook Size and Capacity
- Wire diameter: Thicker wire generally supports more weight. Match the hook’s working load to your application and never exceed the stated limit.
- Opening size: Confirm the end openings will fit over the chain link, rod, or eye you’re connecting to.
- Overall length: Longer hooks reach around bulkier items; shorter hooks keep the hang point tighter to the support.
- Finish: Zinc-plated steel is common for dry indoor use. For damp or corrosive areas, choose a more corrosion-resistant material or finish.
Can S Hooks Be Used for Lifting?
No. S hooks are for light duty hanging and general utility. They are not rated for overhead lifting or life-safety use. Follow the working load printed on the packaging and keep a wide safety margin.
Common Uses for S Hooks
- Hanging tools, hoses, and cords on wire shelving or wall racks
- Suspending signs, baskets, and point-of-sale displays
- Organizing kitchen utensils, pots, or mugs on rails
- Linking chain to tarps, shades, or temporary barriers
How to Close an S Hook
- Attach the hook to the chain, eye, or ring.
- Using pliers, squeeze each open end until the gap just closes around the attachment point.
- Verify the item cannot slip out and the hook still moves freely.
Hooks FAQ
Quick answers to common questions about S hooks so you can choose the right size, finish, and usage for your project.
What’s the difference between S hooks and carabiners?
S hooks hang freely and are great for quick, open connections. Carabiners have a gate that closes, which is better when you want a captive connection that won’t shake free.
Should I pick open or closed S hooks?
Choose open for frequent changes and easy removal. Choose closed (crimped) when you want the connection to stay put or there’s vibration.
How much weight can an S hook hold?
Capacity depends on the hook’s wire diameter and design. Always check the working load marked for that specific size and keep below it.
Will zinc-plated hooks resist rust?
Zinc plating provides basic corrosion protection for indoor, dry areas. For wet or corrosive environments, use a more corrosion-resistant finish or material.
Can I use S hooks outdoors?
They’re fine in covered or dry spots. For long-term outdoor exposure, pick a hook material/finish suited to weather and moisture.
