Product Description

The 1/2-13*1-7/8 Heavy Hex Bolt, a Grade 8 fastener with SAE coarse thread specification, features a 1/2-inch nominal diameter and 13 threads per inch. This 1-7/8" long high-strength bolt complies with SAE J429 standards, offering 150 ksi minimum tensile strength. The zinc-plated surface provides corrosion resistance for automotive, construction, and heavy machinery applications. The heavy hex head design enables 1-inch wrench engagement (15/16" across flats) for secure torque transmission. With a proof load rating of 17,050 lbs and recommended installation torque of 200 ft-lbs (dry), it operates effectively in temperatures ranging from -50°F to 250°F. The SAE coarse thread pattern ensures rapid assembly in high-vibration environments, though requires proper lubrication for optimal performance. Ideal for critical structural connections requiring Grade 8 material hardness (RC 33-39).
