Professional Applications & Engineering Value
These brass slotted pan head screws are engineered to address common industrial challenges like corrosion, electrical conductivity requirements, and assembly efficiency. The rounded pan head design and slotted drive facilitate quick installation in tight spaces, while the fully threaded 4-40 UNC coarse thread ensures strong holding power in materials such as plastics, soft metals, and wood. With a Rockwell B40 hardness and 50,000 psi tensile strength, they resist deformation and loosening in high-vibration environments, making them ideal for electrical enclosures, instrumentation, marine hardware, and precision machinery. The brass material naturally resists rust and galvanic corrosion, reducing maintenance costs and enhancing reliability in demanding applications.
Specification Summary & Compliance
This screw features a 3/8" length, 0.219" head diameter, and Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with ASME B18.6.3 specifications for consistent quality and performance. Additionally, the product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its safety for use in various industrial and consumer applications without hazardous substances.
