English to Japanese Tech/Engineering Mechanics / Mech Engineering chains

Yet another item from the "guess the chain" series - as before, it's an item from a list in a chain specification document, so there's not much context to speak of. The chain can be seen here: http://www.hpionline.com/chainproducts/HighTestChain.htm

Thank you in advance for any and all help you could offer. If anyone knows of any chain-related terminology database or online glossary, I'd be extremely grateful for information about it as well.
