floyd rose nut and pivot screw screw bolt

[bedokkids]

hi,

wonder if anyone has this problem as i am?

the screw head of the bolt holding the guitar saddles and pivot screw had spoiled the my allen wrench. and it's already my third changes. also found the the hextagon shape of the srew head is getting round.



anyone had similar problems, which type of screw would you recommend.?

thanks

yeap my screws' hexagon shape becomes round too. guess its normal wear and tear? i just bought new screws to replace the old ones.
