If you are to use a hex tap bolt in an industrial setting, one of the most important things you will need to keep in mind when using it is how much torque you need to tighten it. This is especially so when you are involved in precision engineering, such as when installing engines of various types. In such cases, how much torque is used in installing the hex tap bolt will determine a lot including how long it’s likely to last.
What are the consequences of not installing the bolt to the right torque?
When there is less than needed stress on the bolt when it has been installed, this could be an indicator that it has not been fastened properly. This then leads to a host of other problems including the risk of having the bond that it is supposed to tighten coming loose. In other instances, the bond being fastened might need to have properties such as being relatively waterproof. If the tension within the tightened hex tap bolt is not enough, it could admit some water into the bond. Tightening the bolt with too much torque also has a number of complications, including running the risk of having the bolt snap under the pressure. It could also make it more difficult to undo the bolt later on.
How to go about it the right way
This then means that when you need to use fasteners such as a hex tap bolt, issues such as how much torque to use when fastening it should always be thought through. Fortunately, there are various ways of finding out how much torque needs to be applied when tightening specific hex tap bolts. One of these is by consulting the fastener distributors that the fasteners are bought from. Most of them offer specs sheets that contain all this information, making it a lot easier for one to make a call on how tight the hex tap bolt should be. This information is also available from the manufacturers of the device you are trying to fasten. In the case of an engine, for instance, the manufacturer will usually specify which types of bolts to use in fastening it, as well as how much torque to use for bolts in specific areas of the engine mounting.
The issue of precision
In some cases, how much torque you need to apply to the hex tap bolts will not be a major issue, and you can afford to take a few liberties when tightening them. However, when installing most equipment, you will need to adhere to strict guidelines governing this. For this reason, it would make sense for you to invest in a torque wrench which gives out a reading of how much torque you are applying on each hex tap bolt to ensure that it’s not too tight or too loose. These can also be rented out from a variety of hardware stores that provide this service. The key issue is that unless you are absolutely sure that you don’t need to be very accurate with this, it would be important to take reasonable steps in ensuring that you use just enough torque.
Started my career in the fastener world in 1969 at, Parker Kalon Corp. a NJ based screw manufacturer located in Clifton, NJ working in inventory control, scheduling secondary production and concluding there in purchasing. In 1971 I accepted a sales position at Star Stainless Screw Co., Totowa, NJ working in inside sales and later as an outside salesman, having a successful career at Star I had the desire with a friend to start our own fastener distribution company in 1980 named: Divspec, Kenilworth, NJ. This was a successful adventure but ended in 1985 with me starting Melfast in August 1985 and have stayed competitive and successful to date. Melfast serves the OEM market with approximately 400 accounts nationally.
