Can You Convert 1970 Honda Philips Head to Metric Head?

The 1970 Honda Philips Head to Metric Head conversion is a common question among automotive enthusiasts and mechanics. Understanding whether you can make this conversion and how it impacts your car’s maintenance and repair process is essential for ensuring smooth work. This article will take you through everything you need to know about converting a 1970 Honda Philips head to metric head.

What is a Phillips Head Bolt?

Before we dive into the specifics of conversion, let’s first understand what a Phillips Head bolt is. The Phillips Head bolt features a cross-shaped slot that requires a Phillips screwdriver to tighten or loosen. These bolts are widely used due to their self-centering ability, making them very popular in automotive, industrial, and household applications.

However, when it comes to working with older vehicles, such as the 1970 Honda, you might encounter bolts that are either difficult to work with or in need of a replacement. The Phillips Head was used extensively in cars built in the 1970s, but today, many car enthusiasts wonder if they can switch to a more modern design like the metric head bolts.

What is a Metric Head Bolt?

A Metric Head bolt, on the other hand, follows the international metric system for sizing. These bolts are more commonly found in modern vehicles and industrial settings. The primary difference between Phillips Head and Metric Head bolts lies in the design of their heads. Metric bolts often feature hexagonal heads or other designs that allow for easier and more efficient tightening with standard wrenches or sockets.

The shift towards metric fasteners in modern vehicles makes them more adaptable to modern tools, unlike Phillips Head screws, which often require specific screwdrivers. Understanding the differences between these two bolt types is crucial when considering a conversion.

Can You Convert 1970 Honda Philips Head to Metric Head?

The question on everyone’s mind: Can you convert a 1970 Honda Philips Head to Metric Head? The answer is yes, but with a few considerations. Converting a Phillips Head bolt to a Metric Head bolt involves removing the old bolts and replacing them with newer, metric-sized ones. The process may sound straightforward, but it requires specific tools and some knowledge of automotive mechanics.

While it is possible to make this conversion, there are a few important things to consider. First, you need to understand whether your vehicle has been modified over the years. Sometimes, previous owners may have already replaced original parts, which can affect the fitment of new bolts.

Why Convert a Phillips Head Bolt to Metric?

There are several reasons why someone might want to convert a 1970 Honda Philips Head to Metric Head bolts. First, Metric Head bolts are more readily available and compatible with modern tools. This can significantly reduce the hassle of sourcing hard-to-find Phillips Head bolts, especially when performing repairs or maintenance.

Secondly, Metric Head bolts tend to provide a better grip and more secure fastening, reducing the risk of slippage during tightening or loosening. This is particularly important when working on components that require a high level of security, such as engine parts or suspension components.

Tools Needed for the Conversion

If you’re looking to convert a 1970 Honda Philips Head to Metric Head, the first step is to gather the right tools. To remove the original Phillips Head bolts, you’ll need a Phillips screwdriver or drill with the appropriate attachment. Depending on the tightness of the bolts, you might also need penetrating oil to loosen rusted bolts.

Once the old bolts are removed, you’ll need a set of metric wrenches and sockets to install the Metric Head bolts. It’s essential to match the exact size and thread pitch of the original bolts to ensure proper fitment.

Steps to Convert a Phillips Head to Metric Head

Here’s a step-by-step guide on how to convert a 1970 Honda Philips Head to Metric Head bolts:

1. Remove the Old Phillips Head Bolts
   Start by using a Phillips screwdriver to remove the old Phillips Head bolts. If the bolts are rusted, use penetrating oil to loosen them up and make the process easier.
2. Select the Right Metric Bolt
   Measure the size and thread pitch of the removed bolts to ensure you select the correct Metric Head replacement bolts. It’s essential that the new bolts fit perfectly into the existing holes to maintain the integrity of the vehicle.
3. Install the Metric Head Bolts
   Once you have the correct Metric Head bolts, use a wrench or socket to install them securely into place. Make sure you tighten them according to the vehicle manufacturer’s specifications.
4. Test the Fit and Tightness
   After the bolts are installed, it’s important to check that they are properly secured and that everything fits without any issues. Tighten each bolt to the correct torque to ensure it remains in place.

Potential Challenges in the Conversion Process

While converting a 1970 Honda Philips Head to Metric Head bolts may seem simple, it comes with some challenges. One common issue is the need to ensure that the new bolts fit into the existing holes without causing damage to the threads. If the threads are worn down, you may need to tap the holes to ensure the new bolts fit properly.

Another challenge is the difficulty of finding bolts that perfectly match the original ones in terms of length and thread pitch. In some cases, you may need to order custom bolts or work with specialized automotive suppliers.

Alternatives to Converting Phillips Head to Metric Head

If you’re not keen on converting a 1970 Honda Philips Head to Metric Head, there are alternatives you can consider. One option is to use an adapter that allows you to use Metric Head tools with the original Phillips Head bolts. This method can be quicker and easier but may not offer the same long-term solution as a complete bolt replacement.

Another option is to replace Phillips Head bolts with Socket Head bolts. These bolts provide a similar benefit to Metric Head bolts, offering a secure and easy fit for modern tools.

Conclusion

In conclusion, converting a 1970 Honda Philips Head to Metric Head bolts is not only possible but can be a great way to make your car repairs and maintenance easier. While the process requires the right tools and some knowledge, it’s a worthwhile investment for anyone looking to modernize their car’s fasteners. By following the proper steps and using the right tools, you can make the conversion smoothly and enjoy the benefits of modern bolts in your classic vehicle.
