Professional Applications & Engineering Value
These 4-40 UNC low wide truss head slotted screws are engineered to address common industrial challenges, such as material fatigue and corrosion in assembly lines. Made from 18-8 stainless steel with a passivated finish, they resist oxidation and chemical exposure, extending service life in sectors like electronics, automotive, and machinery. The truss head profile offers a larger bearing surface, distributing stress evenly to prevent loosening under vibration, while the coarse thread spacing and Class 2A fit ensure quick, accurate fastening without stripping. Ideal for applications requiring robust, fully threaded fasteners, they deliver consistent performance in tight spaces, reducing maintenance needs and downtime.
Specification Summary & Compliance
This product adheres to UNC thread standards with a Class 2A thread fit for precise dimensional accuracy and coarse thread spacing. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufacturing follows industry norms for right-hand threading and full threading along the 1/4" length, supporting reliable integration in various assemblies.
