To be fair the last line of the discerption tells you these are metric keys, NOT SAE. The box is labeled SAE with SAE dimensions. Keys are fair quality at best, box is junk. Evidence of spatulating from the manufacturing process. The keys were all mixed together when I got the box with two different sizes not having the right count. I guess they thought replacing one key with another size was OK and long as my total count was correct.

Great quality and good size range.

These are metric keys labeled with the nearest fractional inch size. They do not fit SAE keyways, and are over or under-sized by 10-50mils. Also, the larger keys (12mm) are not square as indicated, but rather rectangular keys measuring close to 8mm tall.

Decent set, and variety of keys.

container is super cheap and arrived all busted up (no apparent damage to shipping box). I just taped it up, not that big of a deal for me, but a little sturdier container would be nice

Case is broken and items are not organized

Needed a couple of keyways to repair a New Holland haybine which broke down in the middle of hay cutting. Got the equipment back up and running in time to finish before the rains came. Recommend keeping a box of these on hand for emergencies.

I measured these as the fit was very loose, they are metric not sae. You get keys listed as 1/4 but instead they are 6mm for example. Unusable, returned.

It’s clearly labeled imperial but in fact it is metric. I paid extra for imperial.

This contains a wide selection in reasonable lengths. I dont know what is usual. I trimmed one down and it fit well and replaces the original keyway which was damaged when the sprocket ripped open. The case opened inside the envelope during shipping. None were lost, but a piece of tape on the case would deliver a better product.
