Nut & Bolt Thread Checker (Inch & Metric), Original Version (SWTC-26)

Product Information

Customers appreciate the easy to read sizes. The thread sizes are easily identifiable as the bolt plugs themselves are zinc-plated. The SAE sizes are engraved and clearly marked in red paint, with the metric series engraved and marked in white paint. The writing is smaller than that on the wall mounted version, but they are written clearly which helps to make them easier to read. Metric Thread Identifiers contain nut and bolt sizes M4x0.7, M5x0.8, M6x1.0, M8x1.0, M8x1.25, M10x1.0, M10x1.25, M10x1.50, M12x1.25, M12x1.5, M12x1.75. Inch Thread Identifiers contain nut and bolt sizes 1-64, 1-72, 2-56, 2-64, 3-48, 3-56, 4-40, 4-48, and 5-40. Tests by UK technical organisation MIRA found that, once tyres are below 3mm, stopping distances increase dramatically.

Some customers have complained that the size markings are not consistent with some being smaller than others, and some with paint that is faded. Stud Hole Elongation Tester - Push the SHET tool inside the stud hole to the depth of the corresponding size. If any obvious movement is possible then the stud hole has stretched and the wheel should be inspected. However, if you can see the band and that section of the coin is still visible, your tyres could be unsafe and require professional inspection by a mechanic. Metric Thread Identifiers contain nut and bolt sizes M14 X 1.5, M14 X 2.0, M16 X 1.5, M16 X 2.0, M20 X 1.5, M20 X 2.5, M24 X 2.0, M24 X 3.0.

Any insurance claim as a result of an accident could be invalidated, so potentially your insurer won't pay out any money any repairs needed to your vehicle. Some tyres will have indicators embossed on the tyre wall itself, usually with a line or arrow which is positioned somewhere below the outer tread. Tyre and safety experts believe the 1.6mm legal minimum is insufficient to guarantee safety – most recommend a minimum tread depth of 3mm for tyre replacement.

However, they include almost every common size of SAE and metric bolt and thread. Other customers have pointed out the certain specilitary sizes are so rare that many professional woodworkers, machinists, and auto mechanics have never even used them throughout their career. The Final Verdict The difference in wet braking distance between a tyre worn to 3mm and one worn to 1.6mm can be as much as 44%.If there’s less tread depth, less water can be shifted, increasing the risk of aquaplaning and losing grip. Thread gauges traditionally consist of multiple blades that can be used to measure the pitch. The blades sit within a tool that resembles a pen knife. The blades can then be twisted out of the tool when in use. How to use a thread gauge In heavy rain, each tyre can shift one gallon of water every second, illustrating just how hard tyres work. Thelegal tyre tread depth for cars in the UK and Europe is 1.6mmacross the central three-quarters of the tyre, according to law. Pipe Thread Identifiers Pipe Thread Detectives® are precise and easy to use thread identifiers for both male and female fittings. They are especially well-suited for distinguishing between similar National, British and ISO pipe threads.

For more information about tyres read our complete guide to tyre buyingor our complete guide to tyre safety and maintenance. You can buy tyre tread gauges that help you assess the tread depth of the tyre, plus you can also get more basic colour-coded tools that let you know if a tyre is legal or not at a glance. If you are involved in an accident and the car you are driving has illegal or bald tyres, you should be aware of the consequences.Customers are also appreciative that all of the bolt plugs have both a male and female part. This makes it easy to indefinive both threads and bolt head sizes. The Cons The wall mounted version includes all of the common SAE and metric sizes. This takes out any guesswork of the size you need when you make your trip to your local or big box hardware store. Driving with tyres that have a tread below the legal limit - or even worse, are bald - is dangerous.

Once the correct gauge is determined, the user should extend one of the leaves of the tool and press it against the threaded portion of a screw. If the teeth (cut into the leaf) match the spacing of the thread, then the user can read off the thread pitch stamped into the leaf. If the fit is not good, the user should try a different leaf. Thread Gauge Tips To use a thread gauge, first match the type of thread to the gauge. For example, attempting to measure metric threads with an imperial gauge will not return accurate results. To determine the correct gauge, a process of trial and error may be needed if the screw is of unknown origin.
