Review on Metalwork Stainless Steel Fitting Countersunk by Robert Howell

Good product but be careful. With a 3/4" MIP (SAE size), you can expect a square hole to conform to the SAE standard. no 14mm Put it in place with a 1/2" hex and a gasket. Gave me a reason to buy new tools - a full set of SAE and metric hex sockets. Oooh!
