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

Product Information

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 Driving with tyres that have a tread below the legal limit - or even worse, are bald - is dangerous. Metric Thread Identifiers contain nut and bolt sizes M1.2x0.25, M1.6x0.35, M1.6x0.20, M1.8x0.35, M2x0.40, M2x0.25, M2.5x0.45, M2.5x0.35, M3x0.35, M3x0.50, M3.5x0.60, M3.5x0.35. 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. Some customers have complained that the size markings are not consistent with some being smaller than others, and some with paint that is faded.

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. 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. 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. 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. 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.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 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. 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.
