Grade 5, 5/16"-18 Hex Head Cap Screw, Zinc Plated Steel, 1-1/4 in L, 100 PK

The ZORO SELECT - U01200.031.0125 is a Hex Head Cap Screw, a type of fastener characterized by its hexagonal-shaped head. Made from Grade 5 steel and finished with zinc plating for potential durability and corrosion resistance, this screw adheres to the ASME B18.2.1 dimensional standards and SAE J429 material quality standards, intended for use in various industrial applications.

• Drive: The external hex drive requires a wrench or socket of the same shape for installation or removal.
• Fastener Length: With a length of 1-1/4 inches, this is the maximum depth it could potentially reach when inserted into a material.
• Globally Sourced: Procured from international manufacturers offering diverse range options in terms of quality and price.
• Material Grade/Class: Adheres to Grade 5 standard suggesting potential strength, hardness, and resistance properties that may be suitable for certain industrial applications.
• Rockwell Hardness: Rated at HRC19 which suggests its potential resistance to penetration that may affect durability and performance.
• Tensile Strength: Has tensile strength of 105,000 psi suggesting the possible amount stress it might withstand before failure. This does not guarantee suitability or longevity in all situations or uses.
• Thread Direction & Size: Right hand thread direction implies that tightening occurs clockwise; Thread size is 5/16"-18 which could be important depending on the specific requirements of your application
• Thread Style & Type: Fully threaded design covers entire length from tip to head; UNC (Coarse) thread type affects how screw may fit into pre-drilled holes/materials depending on their specifications
