Grade 8, 1/2"-13 Hex Head Cap Screw, Zinc Yellow Steel, 3-1/2 in L, 10 PK

The ZORO SELECT - U04104.050.0350 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. Constructed of steel and coated with zinc yellow, designed to resist corrosion, this screw is made according to ASME B18.2.1 dimensional standards and SAE J429 material quality standards for potential use in 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 3-1/2 inches, the depth at which it can be inserted into materials may vary.
• Globally Sourced: Procured from international manufacturers, offering diverse range options in terms of quality and price.
• Material Grade/Class: It is classified as Grade 8; this classification refers to certain characteristics such as potential strength, hardness, and resistance properties.
• Rockwell Hardness: It has an HRC33 rating indicating its measured level of hardness or resistance against penetration.
• Tensile Strength: Its tensile strength is rated at 150,000 psi; this measurement represents the maximum amount of stress that can theoretically be applied before deformation might occur.
• Thread Style & Type: Partially threaded design suitable for different types of applications with UNC (Coarse) ridges that affect how the screw fits into pre-drilled holes
