Professional Applications & Engineering Value
This 4-40 UNC brass rounded head slotted screw delivers exceptional value in precision assemblies where corrosion resistance and electrical conductivity are critical. The coarse threading provides rapid installation in soft materials while maintaining secure fastening. Engineered with fully threaded design, it eliminates weak points and ensures uniform stress distribution across the entire 1½" length. The rounded head profile minimizes surface marring, making it ideal for finished products and electronic enclosures. With Rockwell B40 hardness and 50,000 psi tensile strength, this fastener withstands vibrational loads while maintaining right-hand thread integrity in demanding industrial environments.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent performance. Features 4-40 UNC coarse threads in inch system measurements with fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets. The slotted drive configuration meets industry-standard tooling requirements for broad compatibility.
