Professional Applications & Engineering Value
This 3/4"-16 UNF hex head screw is engineered to solve critical fastening challenges in demanding industrial settings. The core of its value lies in the 316 Stainless Steel material, which provides exceptional resistance to corrosion from chemicals, saltwater, and other aggressive agents, making it ideal for marine, chemical processing, and food & beverage applications. The combination of a fine UNF thread and a Class 2A thread fit ensures a tight, precise seal that is highly resistant to vibrational forces, preventing joint failure in machinery and equipment. The robust external hex drive and head design allow for the application of high torque, ensuring that the screw's full 70,000 PSI tensile strength can be utilized to create secure, permanent connections in structural and heavy-duty assemblies.
Specification Summary & Compliance
This product features a 3/4"-16 UNF thread with a Class 2A fit for precise dimensional accuracy. It is manufactured to meet the ASME B18.2.1 standard for hex cap screws. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for hazardous substances.
