How to Detect the Bolt Plating Thickness with Plating thickness Gauge?

Bolt is no stranger to everyone. Although it is small, it is widely used in building materials industry and military industry. Depending on the application, the plating on the bolts and the corresponding thickness requirements also vary. The coating thickness on the bolt is usually uneven and its thickness also needs to be strictly controlled. The plating thickness gauge is a coating thickness measurement instrument that professionally measures the plating layer thickness.

1. The plating thickness of bolts needs to be tested!

If the plating layer on the bolt is too thick, it will easily fall off and become rough. If the plating layer on the bolt is too thin, the corrosion resistance may be weakened. The corrosion resistance of the coating usually depends on where the coating is thinnest, that is, where the local thickness is the smallest. The local thickness actually refers to the minimum local thickness, which is the minimum value of the coating thickness that should be achieved on the specified bolt test surface. In addition, the more severe the conditions of use, the thicker the coating is, but the "thick" is also within the specified range.

2. What are the common bolt plating?

The plating layer required on the bolts used in different places is also different. Common bolt plating is as follows:

Base material of plating: steel, iron, copper, zinc alloy, aluminum alloy

Plating materials: nickel, silver, copper, gold

Plating thickness: 0.1, 5, 10, 20μm

Plating type: gloss, semi-gloss, 3-layer nickel, loose hole nickel plating

3. How to detect the thickness of bolt plating?

A professional plating thickness gauge is required for the detection of bolt plating thickness. As a professional coating thickness gauge manufacturer, Linshang Technology provides a variety of coating thickness gauges for customers to choose. LS220, LS220B automotive paint meter for used car industry; integrated coating thickness gauge LS220H for coating industry, marine industry, aerospace industry; split coating thickness gauge LS221, LS223 + F3N3, LS223 + F5N3; plating thickness gauge LS225 + F500 in the hardware industry.

Linshang LS225 + F500 plating thickness gauge is specially used to detect copper, zinc, tin, chromium plating and non-magnetic coatings such as paint, varnish and enamel on ferromagnetic substrates such as steel.

  1. This plating thickness gauge is equipped with an ultra-small probe to measure small-sized materials and heterogeneous materials such as bolts and screws.

  2. Accuracy up to ± (2% reading + 0.3μm) five-point calibration, suitable for measuring ultra-thin platings.

  3. In addition, it is equipped with professional test fixtures, which can eliminate the measurement errors caused by human factors and ensure the stability of the data.

  4. Using digital probe technology, signal processing is done directly on the probe, which is not easy to be interfered.
