Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 12-24 UNC zinc-plated steel screws address critical fastening challenges where corrosion resistance and mechanical strength are paramount. The combination of Rockwell B69 hardness and 60,000 psi tensile strength ensures reliable performance in vibrating machinery, structural assemblies, and heavy equipment. The coarse thread design provides superior holding power in softer materials and faster installation times, while the zinc plating creates a protective barrier against moisture, chemicals, and environmental exposure. These fully threaded screws with Class 2A thread fit deliver consistent clamping force across the entire length, making them ideal for applications requiring uniform stress distribution and reliable long-term performance in manufacturing, construction, and maintenance operations.

Specification Summary & Compliance

This rounded head slotted screw features precise Class 2A thread fit with UNC coarse threading (12-24) and maintains dimensional accuracy per ASME B18.6.3 manufacturing specifications. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. With a standardized 2" length and right-hand thread direction, these screws ensure interchangeability and reliable performance across industrial applications requiring certified components.
