Professional Applications & Engineering Value
This low profile socket head cap screw is engineered to address critical challenges in precision machinery, automotive, and aerospace assemblies where space constraints and vibration are concerns. The black-oxide alloy steel construction provides a durable barrier against rust and corrosion, extending service life in humid or chemically exposed settings. With its 5/16"-24 UNF fine thread and Class 3A fit, it ensures minimal backlash and superior retention in high-vibration environments, reducing maintenance needs. The hex drive and reduced head height facilitate easy installation with standard tools, making it ideal for automated production lines and compact designs that demand reliability without sacrificing performance.
Specification Summary & Compliance
This screw features a 5/16"-24 UNF fine thread with Class 3A thread fit for high precision, a low-profile socket head with a 5/32" hex drive, and dimensions including a 7/16" head diameter and 3/4" length. It is manufactured from alloy steel with a Rockwell C39 hardness and 140,000 psi tensile strength, complying with ASTM A574 specifications. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to international environmental and safety standards.
