The ZORO SELECT - U01200.037.0450 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. This screw is typically used to securely join together materials in various industrial applications such as construction, manufacturing, and engineering projects. Made from steel and finished with zinc plating for enhanced durability and corrosion resistance, this globally sourced product adheres to the ASME B18.2.1 dimensional standards designed for compatibility within the specified ranges.

• Drive: The external hex drive requires a wrench or socket of the same shape for application.
• Fastener Length: The length of 4-1/2 inches refers to the maximum depth it can reach when inserted into a material.
• Globally Sourced: Procured from international manufacturers offering diverse range of quality options.
• Material Grade/Class: The grade 5 classification is based on specific standards relating to strength, hardness, and resistance properties.
• Rockwell Hardness: A Rockwell Hardness measurement of HRC19 is indicative of its potential hardness or resistance to penetration.
• Tensile Strength: It has a tensile strength rating of 105,000 psi which represents the theoretical maximum pulling stress that this screw could potentially withstand before failing under ideal conditions.
• Thread Direction & Size: Right hand thread direction means it tightens clockwise; The thread size is specified as 3/8"-16 which should correspond with appropriately sized nuts or holes in line with standard measurements."
