What do the M4, M5, M6 sizes refer to, and how do I pick the right one?

The 'M' number refers to the diameter of the steel bar in millimetres, so an M8 hook is made from 8mm thick steel. You should choose the size based on the chain or rope you're connecting and the load it needs to handle.

What are the benefits of these being made from 304 stainless steel?

These hooks are made from 304 grade stainless steel, which gives them very good resistance to rust and corrosion. This makes them suitable for use outdoors or in damp environments where a standard steel hook would rust.

Can I use these for lifting heavy loads or for climbing?

No, these are general-purpose snap hooks and are not rated for lifting, overhead loads, or any life-safety applications like climbing. They are ideal for securing items, connecting chains, attaching keys, or for use on tarps and covers.
