Professional Applications & Engineering Value
Engineered for industrial applications requiring durable fastening solutions, these 10-24 UNC zinc-plated steel rounded head screws address critical challenges in machinery assembly, electrical enclosures, and structural frameworks. The coarse thread pattern combined with Class 2A thread fit ensures rapid installation and secure holding power in materials where fine threads might strip. The zinc plating provides essential corrosion protection for equipment exposed to moisture or chemical agents, while the fully threaded design allows for adjustable clamping force across the entire 1-1/4" length. These slotted drive screws with pan head profile deliver reliable performance where vibration resistance and repeated disassembly are common requirements.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread tolerances for consistent quality and interchangeability. The UNC coarse thread (10-24) provides optimal engagement in various materials. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring hazardous substance restrictions are met. Mechanical properties include 60,000 psi tensile strength and Rockwell B60 hardness for dependable performance in industrial fastening applications.
