- Guaranteed compliance and safety meeting ASME B18.2.1 specifications and environmental standards like RoHS 3 & REACH
Professional Applications & Engineering Value
Engineered for demanding environments, these 3/4"-10 UNC brass hex head screws provide a robust solution where corrosion resistance and mechanical integrity are critical. The brass material inherently resists rust and galvanic corrosion, making these external hex drive screws ideal for marine, plumbing, and electrical applications. Their coarse thread design ensures secure fastening in soft materials or where vibration loosening is a concern, while the partial threading offers flexibility for applications requiring a non-threaded shank. With a Rockwell B55 hardness and 50,000 psi tensile strength, they deliver reliable performance in assembly lines, machinery, and structural frameworks, reducing maintenance cycles and enhancing operational longevity.
Specification Summary & Compliance
This 3/4"-10 UNC screw features a Class 2A thread fit for standard tolerance and interchangeability. It is manufactured in compliance with ASME B18.2.1 specifications, ensuring dimensional accuracy and mechanical properties. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for hazardous substances.
