Valve Lash Adjustment Tool, with Angled Feeler Gauge，Jam Nut Valve Adjustment Tool, Slotted Valve Adjusting Stud, Compatible with Honda/Nissan/Toyota/Japanese Auto Vehicle Engines (10mm Model)

Handy tool to keep the the flat head screw calibrated while tightening the bolt.

Excellent product bundle. I checked the feeler gauges with both standard and digital micrometers. The thicknesses are easy to read and very accurate. I would trust these feeler gauges to adjust valves. Haven’t used the actual tool yet but every piece looks good quality. The 10mm hex on the tool is perfect - just right fit, not loose nor tight. No play movement on 10mm bolt. Highly recommended.

I purchased this so that I could adjust the valves on a 95 Honda Beat. It worked for the adjustment on the intake, though the tool was too large to fit in the engine bay for the exhaust, go figure a Japanese Kei car would have issues with tools in the engine bay. Regardless, I then used it on a 91 Honda civic as well and had no issues with intake and exhaust. Its straight forward and easy to use. Its pretty simple and robust, just a 10mm wrench with a flat-head inside, so as long as you don't treat it like a hammer it should last. Although for a simple tool, its a bit more money for what would be used on relatively older vehicles without hydraulic lifters, but it served me well so far and I only have older vehicles. My tool did not come with feeler gauges, so combined with its niche use case and lack of feeler gauges i give this 4 stars. If you have a vehicle that requires valve adjustments, id consider this as it makes the process simpler.

Didn't do the job even once on a 4 cyl engine. The 10mm socket twisted out of shaoe before I was even done on a 16 valve job. The idea of the tool is great, however the quality is subpar. Junk.I would have returned but the return window had just expired. It went straight to the garbage.

Exactly as described

Feeler Gauge print can be hard to see. The screw driver has a bit of play that makes lining up to the adjustment screw tricky. Recommendation for redesign to make the screw driver more stable and wider and sharper slotted tip with adjustment height handle.

Worked great

This helped me complete the valve adjustment on my 2008 2.4L Accord.
