The ZORO SELECT - U04104.031.0075 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. Made from steel and finished with zinc yellow for potential durability and corrosion resistance, this screw is designed to meet ASME B18.2.1 dimensional standards, which may be compatible with various industrial applications.

• Drive: The external hex drive requires a wrench or socket of the same shape for application.
• Fastener Length: With a length of 3/4 inch, this screw is designed to potentially insert deeply into materials for fastening purposes.
• Globally Sourced: Procured from international manufacturers offering diverse range of quality and price options.
• Material Grade/Class: Grade 8 standard suggests potential strength, hardness, and resistance properties that may suit various applications.
• Rockwell Hardness: HRC33 measure implies potential high resistance to penetration which could enhance durability in different environments.
• Tensile Strength: Rated up to 150,000 psi tensile stress before failure suggesting its possible use in heavy-duty tasks.
• Thread Direction & Size: Right hand thread direction tightens clockwise while the size (5/16"-18) is intended to fit with corresponding nuts or holes
• Thread Style & Type: Fully threaded design extends along entire length providing more grip area; UNC (Coarse) thread type is designed to possibly fit securely into pre-drilled holes and materials
