18-8, 1/4"-20 Hex Head Cap Screw, Plain Stainless Steel, 4-1/4 in L, 25 PK

The ZORO SELECT - U51000.025.0425 is a Hex Head Cap Screw, a type of fastener with a hexagonal-shaped head designed for secure joining of materials in various industrial applications. This globally sourced screw adheres to ASME B18.2.1 dimensional standards and ASTM F593 material quality standards, designed for use in a variety of applications.

• Drive: The external hex drive requires an appropriately shaped wrench or socket for installation or removal.
• Fastener Length: With a length of 4-1/4 inches, it provides an indication of potential insertion depth.
• Finish: Plain finish is intended to contribute to durability, corrosion resistance, and aesthetics.
• Material: Made from stainless steel grade/class 18-8, intended to provide strength, durability, and corrosion resistance in certain industrial settings.
• Rockwell Hardness: A hardness rating of HRB80 indicates potential resistance to penetration under specific conditions.
• Tensile Strength: It has a tensile strength rating of 85,000 psi which suggests the capacity to resist pulling stress up until a point under certain circumstances.
• Thread Direction & Size: Right hand thread direction means it tightens clockwise; thread size is 1/4"-20 crucial for ensuring secure fastening with corresponding nuts or holes
• Thread Style & Type: Partially threaded design along with UNC (Coarse) thread type influences how the screw may fit into pre-drilled holes with an aim towards effective material binding
