Professional Applications & Engineering Value
This 316 stainless steel flanged button head screw is engineered to address critical challenges in demanding industrial settings. Its passivated finish significantly enhances resistance to chlorides, acids, and other corrosive agents, making it a top choice for chemical processing, marine equipment, and outdoor infrastructure. The flanged head eliminates the need for separate washers, distributing clamp load over a wider area to prevent surface indentation on soft materials. Combined with UNC coarse threading and a Class 3A fit, it ensures rapid assembly and maintains joint integrity under high vibration, reducing maintenance frequency and downtime in machinery, transportation, and structural applications.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 3A fit for precise, high-strength threaded connections. Dimensions include a 3/8"-16 thread size, 3/4" length, and 0.813" flange diameter. It is manufactured from 316 stainless steel with a passivated finish and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and material restrictions are fully addressed.
