This is a MUST for anyone building engines from stock to full on race!! Excellent for installing head studs, 8mm to 10mm, oil pump studs, the large 12mm studs that hold the case halves together, 6mm oil sump studs and much more. All you do is tighten to desired torque and back in the opposite direction to get your stud installer off. All you need is a 3/8 drive ratchet or 19mm wrench.
Stud Installers: 12x1.5mm, 10x1.5mm, 8x1.25mm, 6x1.00mm
