Proto J3818M Flare Nut Wrench, Alloy Steel, Black Oxide, 18 mm Head Size, 7 1/4 inch Overall Length

Features:

• Ratcheting flare nut wrenches have a gear mechanism on the single head that allows the wrench to rotate freely in one direction without removing the wrench head from the fastener and repositioning the wrench.
• These metric wrenches have a head design on one end of the handle that allows for full contact around the fastener while allowing a line or other obstruction to pass through it. 
• The opposite end provides a more secure grip on the full length of the handle than a double end flare nut wrench. 
• The 12-pt. design has additional grooves that make it easier to connect with the head of the fastener and connect at more angles for better accessibility compared to a 6-pt. wrench.
