Thread not fully cut

I bought 1/2-13 flanged nuts. They will not fit 1/2-13 bolts. I can't get it to the first thread. I pierced one of them just to see and indeed, after tapping, the bolts were fine. The threads inside are all flat, which is something I've never seen before. DO NOT BUY if you intend to use them for anything.

Pros

FEATURES: The serrated flange on the nut acts as an integral washer, effectively and evenly distributing pressure in place. The serrated flange that cuts into the shank increases resistance and provides a reliable, vibration-resistant lock that won't budge.

Cons

Security
