Buying Guide for .38-16 Bolt Size X 1 Inch

Understanding the Basics

When I first encountered the .38-16 bolt size, I learned that it refers to a specific diameter and thread pitch. The “.38” indicates the diameter of the bolt, which is approximately 0.375 inches, while “16” signifies that there are 16 threads per inch. This combination is essential for ensuring a secure fit in various applications.
