Custom Grade 8 Shoulder Bolts

 

These custom shoulder bolts were manufactured to SAE J429 grade 8 requirements for our automotive customer with a black oxide finish.  .57" by .25" shoulder was incorporated under the .5" across the flats hex head and approximately .625" of 3/8-16 thread was rolled to complete the parts.  Certs were available with the parts per customer requirements.
