Tips for Proper Use of Vibration Tester Vol. 1 Maintenance of bolts to be taken care of on a daily basis
11/05/2022
THAI EMIC CO.,LTD.
As a manufacturer of vibration test equipment, Thai EMIC provides contract testing services and sales of test equipment in Thailand and the ASEAN region. We also focus on maintenance, inspection, and calibration services to be “quality partner for customers.” In this first installment of our series to introduce points on the proper use of vibration test equipment, we will discuss on the daily management of bolts and tightening torque.
Daily management of bolts greatly affects the workability of vibration test equipment
When securing a jig to a vibration generator or securing a test piece to a jig, bolts (screws) are used, and the daily management of these bolts greatly affects the workability.
When we visit our customers' sites, we often encounter rusted bolts that have not been adequately maintained are being used.
So how do we properly check bolts?
Check before using the tester! Bolt check Points
The following are specific check points to ensure that proper bolts are used. It is recommended that the person in charge make a habit of checking them on a daily basis as a checklist.
✓ Are the screw threads of the bolts not crushed?
✓ Is the appropriate oil content on the bolts surface maintained?
✓ Are the bolts free of rust?
✓ Are bolts of the proper size (length) used?
✓ When tightening bolts, be sure to use the tightening torque and tighten with an appropriate force (specified value)

*If the threaded part of a bolt is damaged or worn, it should be replaced with a good bolt.
Think of bolts as consumables, and get into the habit of replacing old bolts with new ones.
Bolt tightening torque affects test results and test equipment life
When securing jigs and test pieces with bolts, the tightening torque of the bolts is very important. If the tightening torque is not properly used at the correct specified value, the test results will be greatly affected. If the torque is weaker than the specified value, the jig or test piece will not be secured properly, resulting in rattling or unexpected resonance. Conversely, if the torque is stronger than the specified value, the bolt will break or the jig or test piece will be damaged.
