Gray Tools has introduced a 16-piece insulated hex bit socket set. Made in the U.S.A., the set features both SAE and metric sizes, contained in a carrying case with a foam organizer. All pieces have dual-layer insulation, providing user protection up to 1,000 volts in a variety of electrical applications, the company said.

Gray’s new 3/8-in. drive socket set (part no. 25016-I) includes seven SAE hex head sockets, ranging from 1/8- to 3/8-in., as well as seven metric hex head sockets from 4 to 10 mm. Also included in the set is an insulated 42-tooth round head ratchet and a 3-inch extension attachment.

The company said that every piece in the set undergoes a rigorous multi-step insulation process to meet compliance with ASTM F1505 standards. When the process is completed, each tool is charged with 10,000 volts of energy for 180 seconds to ensure its insulation resists potential electric shock. Other tests are performed to verify the flame resistance and durability of the insulating material.

In addition to offering protection for up to 1,000 volts, the dual-colored insulation serves as a visual safety indicator. If the outer orange layer of insulation becomes damaged, an inner yellow layer alerts the user that the tool is no longer safe for use, the company says.
