Got these nuts took one too a machine shop and got a 1/2 13 tap to thread the hole much easier to get the bolt in especially in very hardwood

Rampa Bolts head seems a bit soft?

I found the Rampa inserts to be great but found the Rampa bolts heads to chew up very easily. Definitely not new to using hex heads, my tools are top notch. Just seemed difficult to not chew up the bolts when slowly tightening.
