1979 Chevrolet Nova/Chevy II STEERING GEAR RAG JOINT COUPLER BOLT 12-POINT GM 748612

STEERING GEAR RAG JOINT COUPLER BOLT 12-POINT GM 748612

THIS IS THE 12-POINT STEERING GEAR RAG JOINT COUPLER BOLT; GRADE 8 BOLT THAT SECURES THE STEERING COUPLER TO THE STEERING SHAFT ON MOST GM VEHICLES. THE ORIGINAL COUPLERS CAME WITH A 12-POINT BOLT IN THE LOCATION WHERE TIGHTENING THIS BOLT SQUEEZES THE COUPLER ONTO THE STEERING SHAFT. THE REASON A 12-POINT BOLT MUST BE USED IS BECAUSE IT IS VERY TIGHT TOLERANCE, AND VERY DIFFICULT TO GET WRENCH TO TIGHTEN UP WITH FULL TURNS WHEN THE COUPLER IS INSTALLED ON CAR. HAVING THE 12-POINT BOLTS MAKES IT MUCH EASIER TO INSTALL.
