Introduction:
Having a rounded bolt can present a frustrating challenge when it comes to removal. Many people may wonder if a hex key set, also known as an Allen wrench set, can effectively solve this problem. In this article, we will delve into the capabilities of a hex key set and discuss its potential in removing a rounded bolt.
Understanding a Hex Key Set:
A hex key set consists of a set of L-shaped tools with hexagonal heads. These tools are available in a variety of sizes to fit different bolt heads or screws. They are commonly made from steel or aluminum and are an essential tool in many industries and households for assembling or disassembling various objects.
Why Bolts Become Rounded:
When significant force is applied to a bolt using an incorrect tool or inadequate leverage, the corners of the bolt’s hexagonal head can start to wear down. Over time, this can lead to a rounded bolt, making it difficult to grip and loosen.
Using a Hex Key Set on a Rounded Bolt:
1. Select the Correct Hex Key Size:
In order to remove a rounded bolt using a hex key set, it is crucial to select the correct size. Using a hex key smaller than the bolt head may result in further damage, while a larger size will not fit correctly. Carefully examining the bolt and comparing it to the hex keys available will help in determining the appropriate size needed.
2. Use Vise-Grip Pliers:
To provide better grip and leverage, it is recommended to use a pair of Vise-Grip pliers alongside the hex key. Firstly, place the hex key into the bolt head as firmly as possible. Then, carefully clamp the Vise-Grip pliers onto the hex key, making sure the jaws have a solid grip on the tool. This will enhance the torque applied and help prevent the hex key from slipping.
3. Apply Extra Force Gradually:
Once the hex key and Vise-Grip pliers are in place, it’s time to start turning the bolt counterclockwise to loosen it. To avoid causing further damage, it is crucial to apply force gradually and steadily, rather than attempting to forcefully break the bolt loose in one go. This will allow the grip on the rounded bolt to gradually loosen, increasing the chances of successful removal.
4. Consider Using Heat or Penetrating Oil:
If the rounded bolt is severely stuck, additional measures may be necessary. Applying heat to the bolt using a heat gun can help expand the metal, making it easier to loosen. However, caution must be exercised to prevent damage to surrounding components. Alternatively, applying a penetrating oil, such as WD-40, to the bolt threads can help to lubricate and break down any corrosion that may be contributing to the bolt’s resistance.
When to Seek Professional Help:
Despite the potential effectiveness of using a hex key set, there may be instances where a professional’s assistance is necessary. If the bolt is severely damaged or there are concerns about the integrity of the assembly, it is advisable to seek professional help. An experienced technician will have the knowledge and specialized tools to safely and efficiently address the issue.
While a hex key set can potentially remove a rounded bolt, it requires careful technique and adherence to the steps outlined above. By selecting the correct size, using Vise-Grip pliers for added grip, applying force gradually, and considering other techniques such as heat or penetrating oil, there is a fair chance of successful removal. However, it is vital to be cautious and seek professional assistance if needed, especially in cases where further damage or safety concerns may arise.
