SOCKET METRIC STAINLES

All Sockethead stainless is 18-8. If other grade are required you can call one of our sales staff with your question @ 1(888) MRBOLTS OR E-mail us at INFO@DMPFASTENERS.COM. All stainless polished bolts are custom polished in our state of the art facility. We remove all knurling and polish to show finish and then they are cleaned with an ultrasonic machine to remove all debree in thread and hex key areas.
