1-1/4-12, right-hand.
What hex size is this jam nut?1-7/8in.
How wide is this jam nut?11/16in.
What material is this jam nut made from?Steel.
Is this jam nut vehicle-specific?No. It is a universal threaded fastener sized by thread and hand; confirm the mating rod end or stud uses the same 1-1/4-12 right-hand thread before ordering.
How is a right-hand jam nut different from a left-hand one?It threads in the standard clockwise-tightening direction; confirm hand orientation matches the mating rod end before use.
Can this jam nut be used with any 1-1/4-12 rod end?Only if the mating part also uses a right-hand thread; verify before use.
Is a matching left-hand jam nut available separately?Yes, QA1 offers a corresponding left-hand version under a different part number; verify the correct part before ordering.
QA1 does not publish a vehicle-specific torque value for this hardware; use general threaded-fastener practice and the assembly manufacturer's specification.
