17.4" Stainless Steel Centralizer

Unique eyebolt fastening design fits easily around the center pipe. ECT's Stainless steel "Worm Drive" centralizers offers a number of advantages to the old "t-bolt" style. No stainless steel nuts to lose! I'm sure you have had the problem of nuts being lost in shipment or on the jobsite. No nuts to install at the drill site. It is necessary to have a "deep socket" to install the "t-bolt" style centralizers. It is also easy to "gall" the stainless bolt during tightening, ruining the centralizer. The tightening torque of our high strength worm drive centralizers is actually higher than the old "t-bolt" style. The worm drive head is smaller than the "t-bolt" design. The threaded t-bolt causes an obstruction in the annulus and can cause problems when using a tremi pipe or installing observation equipment.
