What is a Feeler Gauge?

What is a Feeler Gauge?
By: J. Dillinger

I have seen a few of these around but never knew the purpose of them. Let’s break down what a feeler gauge is.

Feeler gauges are used to measure the gaps in widths between 2 objects. Feeler gauges are made of different thicknesses and lengths. There are two types of units that the feeler gauge uses to measure, the imperial (thousandths of an inch) and metric (millimeter). Feeler gauges are made out of either blades or wire. The wire feeler gauges are used to measure spark plugs.

The most common Feeler gauges are made from high-quality carbon steel and have a very smooth finish. Blade Feeler gauges can also come in an assortment of stainless steel, brass and plastic. However, metal feeler gauges are easier to maintain and have a better wear resistance.

To use a feeler gauge make sure you examine them before each use. Do this by spreading them out making sure they rust-free, but slightly oiled for easy movement. Select one of the smaller blades or wires and try inserting it into the space. If it slips out easy choose the next side up. When both sides of the gauge touch the gap and it moves with gentle pressure, then you’ve found the correct feeler gauge for that gap.

Blade Feeler Gauge

A blade feeler gauge can also be called a flat feeler gauge. A set generally comes in a holder and contains a series of blades with different thicknesses that are stamped for easy identification. A blade feeler gauge is generally flexible and can be used to reach hard places.

Wire Feeler Gauge

The wire feeler gauge is a series of round wires with different thicknesses in a holder usually bent into a U shape and are less flexible than the Blade Feeler Gauge. These wire feeler gauges are more frequently used in the automotive industry.

In case you need a combo unit, there are a few manufacturers that make blade/wire feeler gauge sets. Sometimes having one tool is better than having to keep track of two!

Hi National Tool,

 

I wanted to share a story with you about a product that we recently purchased from you all, The Pig Mat roll. My family and I attend car shows all of the time and if we have a leak, it is a mess to clean up! We have been looking for something that was light-weight and easy to use. This new pig mat towel was so easy to use and we didn’t have to clean up a mess after using them. We placed a couple sheets under the engine compartment while we were at an indoor show and WOW does it work! The oil decided to leak out and it could have gotten everywhere. It was so nice to be able to pick up the mats and just throw them away. A neighbor of ours at the show was so impressed that we gave them a couple to use and they are in love with them also. I would recommend these to anybody out there and you’ll definitely be getting more of our business soon!

P.S. I’ve included a picture of two of our cars that you can share with your employees and your customers.

 

Thank You,

Jerry D.

It’s Gettin’ Hot in Here!

The hot summer weather is blowing in quick! As important as it is to prepare your vehicle for winter, it is just as important to prepare it for the hot summer temperatures. Below I have listed a few tips to get your vehicle in tip-top shape for this summer season.

  • Check your tire pressure – If your tires are under-inflated, this will cause the tire to bulge which will add pressure to the sidewalls of the tire. After enough heat and pressure has affected the tire, BOOM! It will eventually blow. Also, n over-inflated tire makes less contact with the surface of the road and can cause you to hydroplane during the spring and summer storms.
    See what tire pressure gauges are in stock HERE!

Did you know?? – Tire pressure changes with rising temperatures, approximately one to two PSI for every 10 degree increase in outside air temperature.

  • Check your oil and oil filter – ROAD TRIP!!! Wait! Before you leave, make sure you check your oil and oil filter in the vehicle. Long distance drives mixed with hot temperatures can lead to an overheated engine.
    Need to change the oil? Drain Pans make your job easier!

Did you know?? – Oil keeps hardworking engine parts running clean, smooth and cool.

  • De-winterize – Check all the fluids in your vehicle and check for leaks. If you are in extreme snow climates and have snow tires, take them off. Snow tires cause extra weight to the vehicle and are not fuel efficient. Also, clean the undercarriage of the vehicle from salt on the roads.
    Can’t see under your car? These inspection mirrors will help!

Did you know?? – The salt that is used to melt ice and snow on roads can get caked on the underside of your car and begin to eat away at the metal.

  • Check hoses, belts and filters – It is very important to keep the engine cool when driving in the summer heat. Check all of your hoses and belts for cracks, leaks or loose connections. Also, change your air filter if it is clogged with salt or other road debris.

Did you know?? – Replacing a dirty or clogged air filter can improve gas mileage by as much as 10%.

  • Replace your wipers – The winter weather is hard on your wipers. You know, when you get impatient waiting for the windshield to defrost so you use your wipers to speed it up? Ya, I’m guilty. Also, it is important for your wipers to work for the spring and summer storms. I would hate to be stuck on the highway when a sudden storm hits without good wipers!

Did you know?? – At night, a storm can decrease visibility by 15 to 20 feet in front of your vehicle.

  • Keep your battery clean – Dead batteries are common in both winter and summer due to the extreme temperatures. You should detach the battery cables and clean the terminals often. Makes sure that your battery is strapped in correctly and is secure. Also, always make sure you are buying the correct battery for your vehicle if it needs to be replaced.

Did you know?? – Summer heat can speed up the chemical reaction inside a battery, causing the battery to be overcharged. This reduces battery life significantly.

  • Maintain your AC – Most of the time, the cause of a malfunctioning AC is because of low refrigerant. This could be caused by a leak in the system. It is best to have a professional check out the problem since modern AC systems are so complex.

Did you know?? – The best way to tell if your air conditioner has a problem is if it can’t generate or maintain air temperatures that are 50 degrees Fahrenheit below the outside air temperature.
