Professional Applications & Engineering Value
This 4-40 UNC brass rounded head slotted screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The brass material inherently resists rust and is non-magnetic, making it perfect for electrical enclosures, marine hardware, and instrumentation. The wide rounded binding head distributes clamping force evenly, preventing damage to soft materials and ensuring a secure fit in panel mounts and binding posts. With a coarse thread and Class 2A fit, it allows for rapid installation and high resistance to loosening under dynamic loads, while the fully threaded design provides consistent holding power across the entire 3/16" length. This screw delivers reliable performance in demanding applications where precision and durability are critical.
Specification Summary & Compliance
This screw features a 4-40 UNC coarse thread with Class 2A thread fit for standard dimensional accuracy and easy assembly. It is manufactured in compliance with ASME B18.6.3 specifications, ensuring consistent quality and interchangeability. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for use in various industrial and consumer products.
