A chain bolt is a fastening component commonly used in lifting equipment and devices that employ chains. One end of the chain bolt has a male thread, allowing it to be directly screwed into a device. The other end features a head with a hole through which a coupling link for the chain is secured. The load on the chain bolt must be applied axially to avoid damage from angular or perpendicular forces.
Chain bolts are integral in connecting chains and managing tensile strength in various settings, including construction sites and factories. They are particularly useful in situations where chains are needed to support scaffolding or other structures. Given the widespread use of chains in diverse applications ranging from bicycles to industrial machinery and car engines, chain bolts are key components for securely linking chains to equipment.
Chain bolts play a crucial role in applications where chains are used for pulling or lifting. In these contexts, turnbuckles are often employed to adjust chain tension. While turnbuckles are traditionally used for tensioning ropes and wires, they are also effective for adjusting the tensile strength of chains. Chain bolts, which are threaded on one side (single-ended), are a vital part of this setup. They allow for adjustable tensile strength based on how tightly they are fastened. Notably, chain bolts may have either right-hand or left-hand threads.
Constructed primarily from iron or stainless steel, chain bolts are designed to withstand high loads. Different types of chain bolts have varying load-bearing capacities, and those with a rust-proof finish often offer enhanced strength and durability.
