Professional Applications & Engineering Value
These 10-24 UNC zinc-plated alloy steel rounded head screws deliver critical performance advantages in industrial assembly applications. The Torx Plus IP25 drive system significantly reduces fastener damage during high-torque applications, while the Class 3A thread fit ensures precise engagement in machined components. The fully threaded coarse pitch design provides maximum pull-out resistance in materials where vibration resistance is paramount. Engineered with 120,000 psi tensile strength and Rockwell C39 hardness, these industrial fasteners maintain structural integrity under dynamic loads, making them ideal for machinery, automotive subsystems, and heavy equipment where corrosion-resistant properties and reliable performance are non-negotiable requirements.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 3A thread fit tolerances per UNC standards. These fully threaded screws comply with ASME B18.3 manufacturing specifications and maintain compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand coarse threads and zinc-plated alloy steel construction ensure consistent performance across industrial applications requiring reliable fastening solutions.
