Hexagonal head steel bolt is a commonly used fastener, which is widely used in mechanical equipment, building structure and other fields. In order to ensure that its performance meets the requirements of the standard, it needs to be tested.
1. Standard requirements.
The detection of hexagonal head reinforcement bolts should be in accordance with the national standard GB T30981-2010 specified in the hexagon head bolts, screws, nut first part thread and other related standards. The standard requires testing personnel to be familiar with the standard provisions and master the relevant testing points and methods.
Second, the test application process.
When enterprises need to carry out hexagonal head reinforcing rod bolt inspection, they can do it through the following process:
1.Submit an application for testing: Submit an application for testing to the testing and certification body, stating the required testing items and quantity.
2.Determine the testing standards: Confirm the testing standards that meet the requirements with the testing institutions to ensure that the test results are reliable.
3.Sample preparation: Hexagonal head reinforcing rod bolt samples are prepared according to the standard requirements and provided to the testing institution.
4.Testing operation: The testing institution conducts sample testing and records relevant data and results.
5.Publish the test report: The testing institution generates the test report as required and provides it to the enterprise.
3. Testing items.
The test items of hexagonal head reinforcing rod bolts include:
1.Dimensional measurement: measure the length, diameter, thread specification of the bolt, etc.
2.Material Analysis: Analyze the bolt material to determine its composition and properties.
3.Strength test: Tensile, compression and other strength tests are carried out on the bolt to evaluate its bearing capacity.
4.Surface treatment testing: detect the surface treatment of bolts, such as galvanizing, phosphating, etc.
5.Thread performance testing: detect the tooth shape, tooth distance, tooth depth, etc. of the thread.
Fourth, the solution.
For the detection of hexagonal head reinforcement bolts, traditional measuring instruments and testing equipment can be used, and advanced non-destructive testing technology can also be used. Adopting the right solution can improve inspection efficiency and accuracy.
