## Description

The difference between professional and novice is the tool. Powerbuilt 10mm Honda Jam Nut Valve Tool to fill gaps This tool eliminates the frustration of impromptu valve adjustments that require precision.

Review: Great product and good quality for the price. I had a leaking valve cover gasket on our '14 Accord and thought I would check the valve clearance while I had the valve cover off. I purchased this tool ahead of time and I'm glad that I did. The valves did need to be adjusted and there are 16 valves to do. Some valves took several adjustments to get in spec and I went though the procedure twice to double check them all. The job can be done with a screwdriver and a 10mm wrench, but this worked so well and easy. I didn't have to worry about stripping the screw head or the locking nut and I was able to get good torque on the nuts. Recommended if you have a valve adjustment to do.
Review: The right tool for the job. Worked great.
