Bolts play an important role in securing products together. They are often used in critical applications where failure is not an option. That’s why it’s important to ensure that the torque values applied to bolts are accurate. Torque is a critical factor in product assembly. It is the force that keeps bolts and screws in place, ensuring that your product is safe and reliable. That’s why verifying torque specifications is important before you begin assembly.
This blog post will discuss three methods of verifying torque specifications. Each method has advantages and disadvantages, so choose the one that best suits your needs. Let’s get started!
What are Torque Specifications?
Before we discuss how to verify torque specifications, it’s important to understand what they are. Torque specifications are the values that indicate how much force should be applied to a bolt. These values are usually given in Newton meters (Nm) or foot-pounds (ft-lbs).
Torque specifications are important because they ensure that bolts are tightened to the correct level. If too much torque is applied, it can cause damage to the bolt or the product. Conversely, the bolt may come loose and cause problems if too little torque is applied.
Why is it Important to Verify Torque Specifications?
There are many reasons why it’s important to verify torque specifications:
- First, it’s important to ensure that the correct values are being used. If the wrong values are used, it can lead to problems with the product.
- Second, it’s important to verify torque specifications because they can change over time. As products age, they may settle or change shape. This can affect the torque values that are required to keep them secure.
- Third, it’s important to verify torque specifications because they may differ for different product types. For example, a product made of soft materials will require less torque than a product made of hard materials.
In short, verifying torque specifications is important because it helps ensure that products are safe and reliable.
Methods of Verifying Torque Specifications
Traditionally, there are three main test methods for verifying torque specifications. These include the first movement in the fastening direction, the first movement in the loosening direction, and determining the rotation angle by marking the fastener.
Let’s discuss these methods in detail below:
First Movement Torque Test
This method uses a torque measuring tool once the fastener is tightened to a predetermined value. Once the wrench is removed, the torque required to move the fastener in the loosening direction is recorded.
In the tightening direction, start applying force to the tool slowly until the first movement in the fastener is noted. The recorded reading indicates the original torque applied to the joint. This method is the best way to determine residual torque.
Loosening Torque Test
This method is similar to the first movement torque test. But instead of tightening the fastener, torque is applied in the opposite direction to loosen the fastener. Torque reading will be recorded once the fastener breaks loose. The torque to loosen the fastener is the estimated torque applied to the joint.
The loosening torque test measures how much torque is required to break the bond between the two surfaces. This information can be useful in determining how strong the bond is between the two surfaces.
Marking Torque Test
Once the fastener tightens, mark the surface of the fastener, bolt, or nut clearly and continue the mark onto the clamped surface for reference. For this method, loosen and retighten the fastener until the marks on both application and fastener are in line with each other.
The amount of torque required to return the fastener to its original location will serve as a reference to the original torque applied to the fastener. The torque position will indicate how much torque was applied originally.
