Used on Turn-of-Nut & Torque Wrenches for the installation of high-strength hex-head bolts. Featuring a reaction bar to absorb the installation torque.
TONE Bar Sockets are used with Turn-of-Nut and torque wrenches for installing high-strength hex-head bolts. The bar socket design includes a reaction bar to absorb installation torque during tightening.
The product is listed for fully tensioned structural bolts, including A325 and A490 in imperial sizes from 5/8″ to 1-1/2″, and A325M and A490M in metric sizes from M16 to M36. Compatibility is shown separately for Turn-of-Nut wrenches and torque wrenches.
Specification tables map nut dimension across flats, heavy-hex bolt diameter, wrench compatibility, and bar socket weight. Footnotes note that bar socket appearance and size vary by wrench model, and socket weight also varies by wrench model.
