Professional Applications & Engineering Value
This zinc plated steel elevator bolt delivers exceptional value in material handling and industrial machinery applications. The SAE Grade 2 classification combined with 70,000 psi tensile strength provides reliable performance in elevator systems, conveyor belts, and heavy equipment where vibration resistance is critical. The fully threaded UNC coarse threading ensures maximum grip length and prevents loosening under dynamic loads. The wide flat head profile distributes clamping force evenly, protecting sensitive surfaces from indentation while the Rockwell B80 hardness maintains thread integrity through repeated installation cycles. Ideal for maintenance and OEM applications requiring right-hand threaded fasteners with consistent performance in demanding environments.
Specification Summary & Compliance
This elevator bolt features precision 1/4"-20 UNC coarse threading with Class 2A thread fit according to unified standards, ensuring consistent engagement and reliable performance. Manufacturing complies with SAE Grade 2 specifications for strength and dimensional accuracy. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, making it suitable for regulated industrial applications worldwide. Full threading extends to 1 1/32" minimum thread length with right-hand direction for standard installation practices.
