Why I Believe 8-40 Scope Base Screws are Necessary

As an avid hunter and shooter, I have learned the importance of having a reliable and stable scope on my firearm. A quality scope allows for accurate and precise shots, which is crucial when it comes to hunting or competitive shooting. However, many people overlook the significance of scope base screws when setting up their scopes. In my experience, using 8-40 scope base screws has made a significant difference in the performance and longevity of my scopes.

Firstly, 8-40 scope base screws are necessary because they provide a stronger and more secure grip on the rifle’s receiver. These screws have a larger diameter compared to traditional 6-48 screws, making them less likely to strip or break under recoil. This added strength is especially important when using high-powered rifles that produce a significant amount of recoil. With 8-40 screws, I have never had to worry about my scope shifting or becoming loose during shooting.

Furthermore, using 8-40 scope base screws ensures better alignment between the scope and the rifle. When mounting a scope on a rifle, it is crucial to have perfect alignment to achieve maximum accuracy. The larger size of 8-40 screws allows for tighter

My Buying Guide on ‘8-40 Scope Base Screws’

As an avid shooter and enthusiast, I have come to realize the importance of having the right scope base screws for my firearms. These small but crucial components play a vital role in ensuring accuracy and stability when mounting a scope on your rifle. After extensive research and personal experience, I have put together this buying guide to help you make an informed decision when purchasing 8-40 scope base screws.

What are 8-40 Scope Base Screws?

Before diving into the details, let’s first understand what 8-40 scope base screws are. These are screws that are used to secure a scope base onto a rifle’s receiver. The number 8 refers to the diameter of the screw, while 40 indicates the thread pitch (number of threads per inch). These screws are commonly used for mounting scopes on rifles with Picatinny or Weaver style bases.

Factors to Consider

There are several factors that you should consider before buying 8-40 scope base screws. These include:

Material

The most common materials used for making scope base screws are steel and aluminum. Steel is known for its strength and durability, making it ideal for heavy recoil rifles. On the other hand, aluminum is lightweight and corrosion-resistant, making it suitable for hunting rifles.

Thread Engagement

Thread engagement refers to how many turns or threads of the screw will be in contact with the receiver’s threads. This is an essential factor as it determines the strength and stability of the mount. Ideally, you want at least five full turns of thread engagement for a secure fit.

Torx Head vs Hex Head

Scope base screws come in two main types of heads – Torx and Hex (Allen). Torx screws have a star-shaped head, while Hex screws have a six-sided head. Torx screws are known for their better grip and less chance of stripping, making them more reliable than Hex screws.

Length and Diameter

The length and diameter of the scope base screws should match the dimensions of your rifle’s receiver. It is crucial to measure the screw holes on your rifle accurately to ensure you get the right size of screws.

Benefits of Using 8-40 Scope Base Screws

There are several advantages to using 8-40 scope base screws, including:

  • Increased Stability – These screws have a larger diameter than most other scope base screws, providing better stability and preventing any movement between the scope and rifle.
  • Better Recoil Absorption – The larger thread pitch allows for better recoil absorption, reducing the chances of damage to your scope’s internal components.
  • Compatibility – 8-40 scope base screws are compatible with most rifles with Picatinny or Weaver style bases.

After trying out various brands, I have come up with a list of my top three recommended brands for 8-40 scope base screws:

By considering the factors mentioned above and choosing from reputable brands, you can ensure a secure and reliable mount for your scope.
