These are 5 inch long grade 5 one inch bolts .

The 2 middle ones would still work. Though stubby on the left is a bit short for the job of a 5 inch bolt. Or somebody mixed them up at the store/distributor. The one on the lfet might work if needed for a get by situation.
 
Always makes me nuts when people put the wrong bolts in bin . I didnt take time measure the other 3 but to find out much difference there was in length but definitely some
 
I m not sure many people know what quality control means. That has nothing to do with QC. Those bolts are the length they were designed to be.
 
Maybe it's just the picture, but the one on the far right in the picture appears to me to be a larger diameter than the others, and, based on the gauge, they all appear to less than 1 inch diameter.

But, I get the point of the post. Product from the land of ''almost right''.

(quoted from post at 18:39:26 04/29/23) All three are different lengths so what length are
they designed to be
Ask the designer I guess. How long do you think they should be? 5 inches from top of head to tip? Bottom of head to tip? 5 inches of threads? There is no right or wrong, there is no governing body to determine exactly how long each bolt should be. The left and right bolts appear to be about the same, the middle one is a different bolt entirely. So you are comparing different brands and complaining they don t match. Even bolts from the same line may vary a little, they fly though those machines amazingly fast.
 
(quoted from post at 22:02:49 04/29/23) Supposed to be 5 from under the head to the end of
threads . Ill have to see if I can find a video on bolts
manufacturing

ASME standards allow: + 0.120", - 0.160" for a 1" x 5" hex head bolt. (about 1/8" long to about 3/16" short). So other than the one that appears to have been in the wrong bin, I'd say they meet the spec.
