Custom M3 X 0.5MM Stainless Steel Shoulder Socket Bolts

 

These custom stainless steel shoulder bolts were manufactured in 18-8 stainless steel material for our drone manufacturing customer.  M3 X 0.5MM thread was rolled with a thread relief machined below the 4MM X 5MM shoulder.  A 2MM hex drive was broached at the head and a precision machined profile was incorporated on the head to meet drawing requirements.
