- Superior corrosion resistance provided by zinc yellow-chromate plating, extending service life in harsh industrial environments.
- Secure anti-rotation design with a square neck (0.33" width, 0.25" length) that prevents loosening under vibration and dynamic loads.
- Easy and quick installation thanks to UNC coarse threading and fully threaded shank, reducing assembly time and labor costs.
- Consistent dimensional accuracy with Unified Standard Class 2A thread fit, ensuring precise and reliable fastening every time.
- Enhanced durability from Rockwell C25 hardness and steel material, resisting wear and deformation in heavy-duty use.
- Compliance with environmental standards including REACH and RoHS 3, making it suitable for regulated industries and global supply chains.
Professional Applications & Engineering Value
This SAE Grade 5 elevator bolt is engineered to address critical challenges in industrial settings where vibration, high stress, and corrosion are common. The square neck design securely locks into mating surfaces, preventing rotation during operation—ideal for conveyor systems, elevator assemblies, and machinery frames. Its UNC coarse thread and full threading allow for deep engagement and easy adjustment, reducing the risk of strip-out in soft materials. The zinc yellow-chromate plating offers a robust barrier against moisture and chemicals, while the steel construction and high tensile strength ensure long-term reliability in heavy-load applications, minimizing maintenance downtime and replacement costs.
Specification Summary & Compliance
This elevator bolt features a 5/16"-18 UNC coarse thread with Unified Standard Class 2A fit for precise tolerance. It complies with SAE Grade 5 standards, offering medium strength and consistent performance. The product is REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliant, ensuring adherence to environmental and safety regulations. Dimensions include a 2 1/2" length, 1 3/16" flat head diameter, and square neck specifications (0.25" length, 0.33" width), manufactured to meet industrial fastener requirements.
