The Strategic Tools & Equipment LOCKJAW Ratcheting Flare Nut Wrench is a patented, ratcheting open-ended flare nut wrench that works on metric and SAE nuts, including damaged nuts. Its push-on/pull-off feature allows the tool to be used with one hand while its ratcheting design allows users to ratchet around the nut without removing the tool from the nut. The flare nut wrench also offers ideal gripping strength. The more leverage exerted on the tool, the tighter the grip on the nut, the company says. Sizes include 8-9mm, 10-11mm, 12-13mm, and 14-5mm as well as SAE sizes: 5/16” by 11/32”, 3/8” by 7/16”, 15/32” by 1/2”, and 9/16” by 19/32”.
