Product Description

The 1/2-13*1-3/8 Bolt is a precision-engineered 1/2-13 Threaded Fastener designed for industrial assembly applications. This 1-3/8 Machine Screw features a 1/2-inch diameter with 13 threads per inch and a 1.375" shank length, crafted from grade 8 steel for tensile strength up to 150 ksi. It operates in temperature ranges from -50°F to 450°F (-45°C to 232°C) and withstands vibration loads up to 8G. Commonly used in heavy machinery, automotive, and structural engineering, the fastener excels in high-stress environments due to its zinc-plated corrosion resistance and hexagonal head design for 3/4" wrench compatibility. While optimized for torque ratings between 90-120 ft-lbs, installation requires calibrated tools to prevent thread deformation. Its compact profile enables use in confined spaces without compromising shear strength.
