This is the same 701, we just implemented a new number system to distinguish SS Niles top-quality stoppers from the copy cats. If it doesn't say "SS Niles", it is definitely not the same improved quality and materials I have been using for over 3 years. These stoppers have a 3/8" x 16 threaded stud 1/2" long, one piece with stopper. Top diameter of stopper is 13/16", 1 1/2" total height without stud. Use an 5/16" or 9mm drill bit.
