Professional Applications & Engineering Value

This 1/4"-20 UNC elevator bolt with flat wide head design addresses critical challenges in material handling and industrial equipment applications. The SAE Grade 2 steel construction provides excellent durability while maintaining sufficient ductility to withstand vibration and impact loads common in elevator systems and conveyor installations. The fully threaded right-hand coarse threading ensures rapid assembly in time-sensitive maintenance scenarios, while the wide head profile distributes clamping force effectively across softer materials like rubber and composite surfaces. With Rockwell B80 hardness, these bolts maintain thread integrity through repeated installation cycles, making them ideal for industrial fastening applications requiring reliable, long-term performance.
