Proto J3700A Flare Nut Wrench Set delivers professional-grade performance with seven double-end SAE wrenches spanning 3/8 in to 3/4 in. The 6-point design maximizes contact with fastener sides, significantly reducing corner rounding compared to 12-point alternatives. Each wrench features dual sizes for versatile applications, while the fixed head design includes a line-pass opening for working around obstructions. Crafted from durable alloy steel with a satin finish, this set is engineered for technicians who demand precision and reliability in demanding fastening tasks.
