3 Easy Steps
EZ Calc is an online tool provided by Enerteq Solutions that allows you to estimate required torque values for bolting. It helps you determine the following parameters:
- Torque: The twisting force applied to a bolt.
- Bolt Load: The axial force exerted by the bolt.
- Percent Yield: The percentage of the maximum load the bolt can handle.
Step 1
Go To EZ-Calc
Click the image or EZ Calc link to calculate your torque requirements.
Step 2
Calculate Torque Requirements
Fill out the form according to your application specifications. Use the graph below as a guide.
Step 3
Tool Selection
After calculating your required torque, use the guide below to find the best tool for your application.
Important Disclosure: EZ Calc uses the Mechanical Engineering “Short Formula” and other estimating techniques, which can be subjective. The results should be used as guidance. Enerteq Solutions, Inc. assumes no responsibility for their use.
