Professional Applications & Engineering Value
These 8-32 UNC brass screws with Class 3A precision threading are engineered to solve critical fastening challenges in industrial settings. The rounded button head design combined with coarse thread spacing provides rapid installation and superior holding power in soft materials and sheet metal applications. The brass material offers natural corrosion resistance without sacrificing mechanical performance, making these fully threaded screws ideal for electrical enclosures, marine equipment, and plumbing systems where galvanic corrosion is a concern. With 50,000 psi tensile strength and Rockwell B55 hardness, they maintain thread integrity even under vibrational stresses, reducing maintenance needs and preventing costly assembly failures in industrial fastening solutions.
Specification Summary & Compliance
These screws feature 8-32 UNC coarse threads with Class 3A thread fit for precision engagement, 1 3/8" fully threaded length, and 0.312" head diameter with standard rounded profile. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) compliance, ensuring environmental responsibility while maintaining the mechanical properties required for industrial applications.
