Professional Applications & Engineering Value
This 18-8 stainless steel rounded head screw is engineered to solve critical challenges in industrial assembly and machinery. Its Class 3A UNC coarse thread ensures a precise, durable fit that resists loosening under dynamic loads, making it ideal for high-vibration applications in automotive, electronics, and heavy equipment. The fully threaded, vented design is particularly valuable in pressurized systems or sealed enclosures, where it prevents moisture buildup and corrosion. With a Rockwell B81 hardness and 80,000 psi tensile strength, it provides long-term reliability in corrosive or high-stress environments, reducing maintenance frequency and downtime. The hex drive allows for secure tool engagement, facilitating efficient installation in confined spaces.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with a Class 3A precision fit, ensuring tight tolerances and reliable performance. It is manufactured from 18-8 stainless steel and is fully threaded with a right-hand thread direction. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting stringent environmental and safety standards for industrial use.
