Professional Applications & Engineering Value
This SAE Grade 2 steel elevator bolt is engineered to address common industrial challenges like material fatigue and assembly inefficiency. The fully threaded 1/4"-20 UNC coarse thread design ensures maximum grip in elevator systems, conveyor belts, and machinery bases, where vibration resistance is critical. The wide flat head distributes clamping force evenly, reducing the risk of surface indentation in softer materials like rubber or wood. Manufactured from high-strength steel with a Rockwell B80 hardness, it withstands repetitive loads without deformation. Its right-hand threading and Unified Standard Class 2A precision enable quick, secure installations, making it ideal for maintenance and OEM applications requiring reliable, heavy-duty fasteners that comply with environmental regulations.
Specification Summary & Compliance
This elevator bolt adheres to Unified Standard Class 2A thread fit and UNC coarse threading standards, ensuring dimensional accuracy for inch-system applications. It meets SAE Grade 2 specifications with a tensile strength of 70,000 psi and is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, guaranteeing safe, environmentally responsible use in industrial settings.
