5PCS 3.15" Stainless Steel Carabiner Clip, 600-lb WLL Snap Hook for Gym.

These seem to be nice caribiners. I an using one for a break tearaway cable on my trailer. The caribiner that came with it was too small, this one will fit the bill.

Well made with a nice finish. They are not aluminum, that's obvious when you pick it up.😎

These are very well designed and of high quality.

Worked well for our gates. Carabiner fits easily through 2.0 passing link chain

Appears to be good stuff!I’m not sure this is actually 304 stainless steel; stainless steel, even 304, is generally not magnetic. It is however, possible for 304 stainless steel during cold working (e.g., bending) to become magnetizable.In this case, a magnet is very strongly attracted to the carabiner (suggesting potentially a low alloy content, although could be due to reforming). In the included photo, showing the carabiner suspended when attached to a common magnet - the magnet is very strongly attracted to the carabiner, even able to hold his own weight (i.e. raising, questions of the quality of the stainless steel)However! I ran a short term corrosion test - I previously worked in R&D in the oil industry - the highest corrosion rate is not from something continuously submerged in seawater, but rather is an environment where things are exposed to seawater and then air, either through spray or submersion exposure followed by exposure to air, in a repeated fashionI conducted a short term test here where I dipped the carabiner in salt water over a half dozen times allow it to dry, and repeated; the good news was, no visible signs of surface corrosion! Good news indeed!The carabiner will now be entering service on a boat occasionally taken offshore; it will see limited direct exposure (to seawater), but hoping it’ll last over a decade.

SUPERB QUALITY.

product as described, quick delivery, the defining characteristic will be if the hinge pin is steel or stainless.

Easy to use and versatile Carabiners made from my favorite metal, Stainless Steel! Use these to ensure doors and ramps stay closed on my cargo trailers during short transits without having to continuously fumble with locks and keys. The diameter of the units fills the matching holes enough to prevent any rattling of metal on metal. The spring strength is sufficient to hold the unit closed and not so much that regular trips to the gym are necessary to strengthen the thumb muscles!! On longer trips, locks and keys are necessary for security purposes.
