Professional Applications & Engineering Value
This ribbed neck elevator bolt is engineered to address common challenges in material handling and industrial systems, such as bolt slippage and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to rust and chemicals, making it suitable for food processing, marine, and outdoor applications. The ribbed neck design bites into surfaces, providing a non-slip grip that maintains alignment under dynamic loads, while the UNC coarse thread ensures quick installation and reliable holding power in wood, metal, or composite materials. With a flat head profile and slotted drive, it allows for flush mounting and easy access in confined spaces, reducing maintenance downtime and improving operational safety in conveyor belts, elevator systems, and heavy machinery.
Specification Summary & Compliance
This elevator bolt features precise Unified Standard Class 2A thread fit and UNC 1/4"-20 coarse threading for consistent performance. It complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and material sustainability. Dimensions include a 1-1/2" length, 0.25" screw diameter, and ribbed neck with 0.24" diameter and 0.11" length, manufactured to standard industrial specifications for reliable use in various sectors.
