1950-1979 Valve Adjust Screws 8mm 1200cc-1600cc 043198451 - OEM Number(s) (043-198-451)
This reproduction eight-piece valve adjusting screw set restores precise, reliable valve lash adjustment on your air-cooled Volkswagen engine, replacing worn or rounded originals.
This reproduction Volkswagen valve adjusting screw set gives you a full complement of fresh 8mm screws for your air-cooled engine. Threaded into the rocker arms, these screws set the clearance between rocker and valve stem, and worn, mushroomed, or rounded screws make a clean, repeatable adjustment hard to hold.
Supplied as a complete eight-piece set — enough for a full four-cylinder engine — they are the right starting point any time you are adjusting valves, rebuilding the top end, or refreshing tired rocker gear. Setting fresh screws lets the locknut torque down clean and the lash stay where you put it.

Because Details Matter: Valve lash is one of those settings that quietly governs how your engine runs, idles, and lasts. Starting with fresh adjusting screws means the clearance you dial in is the clearance that stays — and that translates to a smoother, healthier, longer-lived air-cooled motor.
