Grade 5, 5/16"-18 Hex Head Cap Screw, Black Oxide Steel, 1-1/2 in L, 100 PK

The ZORO SELECT - U01000.031.0150 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. This screw is constructed of steel, finished with black oxide which may contribute to its durability and potential corrosion resistance. It complies with the ASME B18.2.1 dimensional standards ensuring compatibility in various industrial applications.

• Drive: The external hex drive requires a wrench or socket of the same shape for installation or removal.
• Fastener Length: Has a length of 1-1/2 inches; the depth at which it is inserted into material should be determined by user based on specific application needs.
• Globally Sourced: Procured from international manufacturers, offering diverse range of quality and price options.
• Material Grade/Class: Complies with Grade 5 standards; these standards suggest certain strength, hardness, and resistance properties. Suitability for specific applications depends on individual use-case scenarios.
• Rockwell Hardness: HRC19 rating measures hardness or resistance to penetration affecting durability and performance in different environments.
• Tensile Strength: Tested under conditions up to 105,000 psi tensile stress before failure. Its performance in real-world heavy-duty applications will depend on numerous factors beyond this laboratory test condition.
• Thread Direction & Size: Right hand thread direction tightens clockwise; thread size is 5/16"-18 crucial for ensuring secure fit with corresponding nuts or holes.
