Overview

The Minerallac Company 55031J is a 1/4-20 x 2 inch hex head tap bolt engineered for heavy-duty industrial fastening applications. Constructed from medium carbon steel, this Grade 5 bolt undergoes a quench-and-temper process to achieve superior tensile strength, making it ideal for demanding environments where robust connections are required. The fully threaded design ensures consistent engagement across mating surfaces, reducing the risk of loosening under vibration or dynamic loads. This zinc-plated bolt provides enhanced corrosion resistance, extending service life in outdoor, marine, or chemically aggressive environments. The hex head design allows for secure wrench or socket engagement, enabling efficient installation and removal with standard tools. Packaged in a gravity-feed jar containing 100 bolts, the 55031J is optimized for high-volume distribution and quick access in industrial maintenance, construction, and machinery assembly operations. Key applications include structural steel connections, machinery mounting, equipment assembly, and general-purpose fastening where a strong, reliable threaded fastener is required. The 1/4-20 thread size is a common standard in industrial hardware, ensuring compatibility with a wide range of nuts, washers, and tapped components. Unlike lower-grade fasteners, the Grade 5 designation guarantees a minimum tensile strength of 120,000 psi and a yield strength of 92,000 psi, providing confidence in load-bearing applications. The tap bolt design eliminates the need for separate nuts in many applications, as the threaded shank can be inserted directly into pre-tapped holes. This feature simplifies assembly, reduces part count, and minimizes the risk of loose hardware. The 2-inch length provides sufficient thread engagement for most industrial connections while maintaining a low profile in tight spaces. For applications requiring stainless steel corrosion resistance, Minerallac offers equivalent tap bolts in Type 18-8 stainless steel (e.g., SKU 74216J for 1/4-20 x 1" and 74242J for 1/4-20 x 2-1/2").
