Professional Applications & Engineering Value
Engineered for precision and durability, these brass socket head cap screws with 4-40 UNC coarse threads address critical industrial challenges. The Class 3A thread fit minimizes backlash and enhances joint integrity in high-vibration environments like machinery, electronics, and automotive systems. The corrosion-resistant brass material ensures long-term performance in humid or chemically exposed settings, reducing maintenance costs. Combined with a 50,000 psi tensile strength and Rockwell B55 hardness, these fasteners provide reliable clamping force for components requiring repeated adjustments. The 3/32" hex drive allows secure tool engagement, speeding up assembly while preventing strip-out, making them ideal for precision equipment and tight-clearance applications.
Specification Summary & Compliance
This fastener adheres to UNC thread standards with a Class 3A precision fit for tight tolerances and consistent performance. Manufactured to inch system measurements, it features a right-hand thread direction and fully threaded rod type. Compliance with REACH (EC 1907/2006) regulations ensures environmental safety and material sustainability, supporting responsible industrial use without compromising on mechanical properties like hardness and tensile strength.
