DISEN 9pcs Torque Adapter Set SAE, Durable Torque Wrench Adapter, Torque Adapter 3/8" Drive, 12 Point, Set Including 3/8", 7/16," 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8"

I am a helicopter mechanic. Bought this set specifically for the 3/4" adaptor and it broke on the very first use at 900" lbs. Our torque wrenches are calibrated twice a year, so it wasn't the ratchet. Highly disappointed.

First attempt to use one of this set it shattered into several pieces. Made me feel like the Hulk instead of the 90lb weakling that I am. Returned the set for full refund without a problem. Replacement made by Proto worked without issue so I guess I'm not the Hulk after all.

Was using to torque a 1/2 bolt. It broke at 30ft lbs. Torque on the bolt is 75ft lbs. Haven't used the rest yet but am already looking for replacements because I don't trust these.

I found these to be very useful in alot of places. But i bought specifically for 2 sizes. 1/2" & 7/16". Someone messed up packing the set because I got (2) 1/2" and no 7/16. Kinda a bummer

Easily took apart and reassembled my harley with ease. Cannot torque the rocker box's up without.
