The ZORO SELECT - U04100.062.0350 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. Made from steel and finished with black oxide for enhanced durability and corrosion resistance, this screw is intended for use in joining materials together in various industrial applications. With its globally sourced manufacturing, it provides a variety of choices suitable for different needs and budgets.

• Drive: The external hex drive requires a wrench or socket of the same shape for application.
• Fastener Length: Measuring 3-1/2 inches long, it suggests the potential depth of insertion into material.
• Material Grade/Class: With a grade 8 classification, this screw is rated with certain strength, hardness, and resistance properties that may be appropriate for demanding applications.
• Rockwell Hardness: A HRC33 rating is an indication of the measured hardness or resistance to penetration which may influence durability and performance under specific conditions.
• Tensile Strength: Rated with tensile strength at 150,000 psi (pounds per square inch), this screw has been tested to resist certain levels of pulling stress under specified conditions. Its durability and reliability may vary based on usage within its rated specifications.
• Thread Direction & Size: The right-hand thread direction implies that it tightens when turned clockwise. The specified size (5/8"-11) is intended to match corresponding nuts or holes but does not guarantee perfect fit or secure fastening without proper installation techniques being followed by users."
