Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc plating for extended service life in demanding industrial environments
- High tensile strength of 60,000 psi ensures reliable fastening under significant mechanical stress
- Rockwell B69 hardness provides excellent durability and resistance to wear during installation and use
- Class 2A thread fit offers optimal assembly clearance for efficient installation while maintaining secure hold
- Phillips No. 3 drive design enables quick, secure tool engagement and reduced cam-out during tightening
- Fully threaded construction delivers maximum grip length and uniform load distribution along the entire fastener
- Coarse UNC threading provides faster installation and superior performance in softer materials or where debris accumulation is a concern
Professional Applications & Engineering Value
These 12-24 UNC zinc-plated steel screws deliver exceptional engineering value across industrial applications where corrosion resistance and structural integrity are paramount. The rounded head design with Phillips No. 3 drive combines secure tool engagement with a low-profile finish, making them ideal for machinery assembly, electrical enclosures, and equipment manufacturing. The coarse thread spacing ensures rapid installation in various materials while the Class 2A thread fit provides the perfect balance between assembly efficiency and vibration resistance. With 60,000 psi tensile strength and Rockwell B69 hardness, these fasteners withstand substantial mechanical stress without compromising performance, solving critical challenges in maintenance-intensive environments where reliability cannot be compromised.
Specification Summary & Compliance
These screws feature precision 12-24 UNC coarse threads with Class 2A thread fit tolerances, ensuring consistent performance across industrial applications. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming they contain no restricted substances and meet current environmental regulations for industrial use.
