Grade 8, 1-4"-20 Hex Head Cap Screw, Zinc Yellow Steel, 3 in L, 50 PK U04104.025.0300

The ZORO SELECT - U04104.025.0300 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. This industrial-grade screw is intended for use in joining materials together in a variety of applications including construction, manufacturing, and engineering projects. Constructed from Grade 8 steel with a zinc yellow finish intended to enhance durability and corrosion resistance, this cap screw complies with the ASME B18.2.1 dimensional standards and SAE J429 material quality standards. Drive: The external hex drive requires an appropriately shaped wrench or socket for installation or removal.Fastener Length: With its 3-inch length, this screw may be inserted into material up to that depth.Globally Sourced: Sourced globally from multiple manufacturers providing diversity in product options.Material Grade/Class: Complies with the Grade 8 standard which suggests potential suitability for heavy-duty applications based on its strength, hardness and resistance properties.Rockwell Hardness: Has an HRC33 rating which is used as an indicator of hardness or resistance to penetration; these factors may affect overall durability and performance.Tensile Strength: Features tensile strength rated at 150000 psi. This rating represents the theoretical maximum pulling stress that could potentially be tolerated before failure. It's important to note that actual results may vary depending on specific usage conditions.Thread Direction & Size: Right hand thread direction tightens clockwise while its size (1/4"-20) ensures fit with corresponding nuts or holes crucial for secure fastening
