NBK Chain Bolts, Turnbuckles
Chain bolts and turnbuckles are members used to fix chains. A joint is inserted into the hole at the end of the chain bolt, and then the chain is attached to this joint to fix it. Each end of a turnbuckle is equipped with a hook. Not only can the hooks at each end be attached to 2 chains to fix them, but the center part of the turnbuckle can also be turned to pull the chains and adjust their tension while fixing them. This product can be used not only for chains, but also wires and ropes. A common material is steel or stainless steel. Be careful because the load capacity value differs according to type. If you need a chain bolt or turnbuckle with higher strength or load capacity, a type with a rust-prevention coating or manufactured for JIS construction is recommended.
