Feeler guage

hat is a feeler gauge?�
A feeler gauge is a hand-held measuring tool.
It has a number of folding metal strips (also known as blades, or leaves) which are machined to specified thickness levels.
Measurements are given in millimetres or inches and can be found in a central location on each individual strip.
A feeler gauge fits into small gaps, often less than 5.08mm (0.200").
The gauge gives you an idea of how wide a gap is by physically filling the space with metal strips which have a known thickness value.
Feeler gauge sizes
Feeler gauges can take measurements as small as 0.02mm (0.0008") and as large as 5.08mm (0.200").
The size of a feeler gauge as inscribed on the tool refers to its thickness.
How do feeler gauges differ from other measuring devices?
A feeler gauge is different from many other measuring devices as it provides you with a visual clue of how wide the gap you are measuring is by physically filling the gap with metal strips.
Feeler gauges are ideal for use in spaces where other measuring devices, such as a tape measure or caliper could not fit. 
What are the different types of feeler gauge?
There are 6 types of feeler gauge available:
1. Go No Go feeler gauge
2. Straight leaf feeler gauge
3. Tapered feeler gauge
4. Double ended gauge
5. Offset gauge
6. Feeler strip.
How to handle
use
A similar device with wires of specific diameter instead of flat blades is used to set the gap in spark plugs to the correct size; this is done by increasing or decreasing the gap until the gauge of the correct size just fits inside the gap
MATERIAL
High carbon (C1095),
Close grain,
Spring steel

High carbon content ensures that the material does not compress, producing consistent accuracy, which is the most important aspect of this precision measuring tool.
Price and manufacturer
Price is vary from 200 to 2000 rupees as per the accuracy.
Leading manufacturer of feeler gauge is as below,

A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts.[1]

They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece. They are flexible enough that, even if they are all on the same hinge, several can be stacked together to gauge intermediate values. It is common to have two sets for imperial units (typically measured in thousandths of an inch) and metric (typically measured in hundredths of a millimetre) measurements.

12. STORAGE Feeler gauges should be cleaned with an oily cloth before storage to prevent rust.  penetrating oil is used for protecting against the rust.
