Description

Measuring the size between two objects can be complicated, especially if they are very close together. However, you can get the job done quickly and easily with our bent feeler gauge set. Our spark plug gauge gap tool includes 12 heavy duty blades. To help you measure the space between two objects that are difficult to reach, these blades are designed with a 30-degree offset. Get this offset valve feeler gauge set and don’t risk bending other blades by trying to reach inside a tight area. These angled feeler gauge blades are also 4 inches long, which gives you reach while being compact and easy to use. This go no go feeler gauge kit includes both metric and SAE measurements clearly stamped one right under the other on each blade, so they are easy to see. The measurements on this SAE and mm feeler gauge set come in a wide range, starting at 0.008 inch (0.203 mm) and finishing at 0.26 inch (0.660 mm). No matter what you are measuring, our spark plug gap gauge set will have the right size you need. Because you use feelers in between tough automotive parts, they need to be durable enough to withstand the wear. Each of the blades within our valve clearance feeler gauge kit are composed of hardened and tempered steel, so you never have to worry about breaking them on the job. If you need to remove a certain size from this motorcycle feeler gauge, this can be done effortlessly. All you need to do is find the size you want and loosen the thumb notch on the go no go gauge to easily remove the blade. When measuring between two objects that are close together, you need this durable metal feeler gauge set. From the Manufacturer The OEM 25304 Value Tap Feeler Gauge 12BI features 12 offset 30 degree blades that are four inches long and measure .008-inch (.203mm) to .026-inch (.660mm). Each blade is laser etched with inches/mm. Hardened tempered steel blades. Blade protector with thumb notch to aid in easy removal.

Great set of gauges for occasional homeowner use!
Size: 26 BLADE
This is a medium-quality feeler gauge best suited for occasional use by home mechanics. I bought this one because the price was much lower than true "professional" quality gauges and because I don't need a professional set of gauges for heavy use. I need a set of feeler gauges to check spark plug gaps every so often (a couple times a year) and to set valve clearances on some of my small engine equipment (lawn mowers, etc). I probably use these feeler gauges every 2 months at best. For these purposes, this set of gauges is perfectly adequate. The blades are smooth on the edges with no burrs, and the sizes are etched on and clearly readable. The only drawback is that the gauge set came in a bag heavily covered in oil (as other reviews have mentioned). This is likely machine oil to prevent corrosion during shipping, but you should be prepared to wipe down the gauges before first use, and you may want to wear a set of disposable gloves. I'm very satisfied with these gauges. They do the job and were at the right price point for a homeowner with a few semi-regular uses for them. ... show more

Oily, but a great tool
Size: 26 BLADE
Exactly what I needed for setting up my guitars. Good construction and very easy to use. Pros: Gets the job done, and the numbering is very big and easy to read on each feeler. Nice to have the little knob on it to tighten when you want to close it and keep it closed. Then you can simply loosen it to find the feeler that you need, then lock it back in place with a turn to use it. Solid all metal construction, seems to be something that will last, my only concern would be if the numbers ever faded. But they are in order, so if you have most of the numbers, you could figure out what's in between. Cons: As other viewers have said, there is some oil on each of the blades, which might be necessary. I don't think this thing is made of stainless steel, so a little lubrication is not a crazy idea here, but still, it will get on your hands when you use it. Conclusion: This is a great tool for setting up your guitar or whatever else you need. It has a lot of different-sized feelers and basically every increment from end to end is filled in and accounted for. I highly recommend this product, especially for the price. ... show more

A good tool to have when you need it!

Nice. Good quality, tested thickness with a digital caliper and they are right on. You probably won't use these very often, but they sure come in handy when you need them.
