Professional Applications & Engineering Value
Engineered for demanding industrial binding and assembly tasks, these rounded head slotted screws solve critical challenges in machinery, electrical enclosures, and fixture manufacturing. The combination of 18-8 Stainless Steel and a passivated finish provides superior resistance to rust and chemical exposure, extending service life in corrosive environments. The wide rounded head distributes clamping force effectively, preventing pull-through in softer materials, while the fully threaded UNC coarse design ensures quick, secure fastening. This makes them an ideal choice for applications requiring robust, high tensile strength fasteners that maintain integrity under vibration and load.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC thread with coarse spacing and a Class 2A thread fit for standard dimensional accuracy and ease of assembly. It is manufactured in compliance with the ASME B18.6.3 specification and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability for global industrial use.
