1-1/2": The nominal major diameter of the bolt is 1.5 inches.
13: There are 13 threads per inch (TPI).
UNC: Stands for Unified National Coarse. This is the standard coarse thread series, which is preferred for general applications because it is highly resistant to cross-threading and allows for faster assembly.
The total overall length of the bolt from the underside of the head to the tip is 2.25 inches.
ASTM: American Society for Testing and Materials.
A307: This is a standard specification for low-carbon steel external or internal threaded fasteners.
Strength: It has a minimum tensile strength of 60,000 PSI (60 ksi). It is an economical, general-purpose grade and is not considered a high-strength structural bolt (like ASTM A325 or A490). It is commonly used in non-critical structural connections, pipe flanges, and general machinery.
Unlike fully threaded bolts, a half-threaded bolt has a smooth, unthreaded shank between the head and the threaded portion.
Advantage: The unthreaded shank acts as a precision dowel, providing better shear strength and alignment in structural connections.
It features a standard six-sided head, designed to be driven with a wrench or socket.
Ideal For: General machinery, structural connections, piping systems, and non-critical indoor assemblies.
Important Note: The black oxide finish provides limited corrosion resistance and is strictly intended for dry, indoor environments. For outdoor or corrosive conditions, please consider hot-dip galvanized or zinc-plated alternatives.
Disclaimer: The code "X118" is included as a reference identifier. Please verify its specific meaning (e.g., internal part number, batch code, or manufacturer mark) with your engineering or procurement team before finalizing the order.
