20mm 1/2" Drive Insulated Socket

The Gray Tools M1220-I is a 20mm, 12-point socket built for 1/2" drive tools. It carries a 1000 V insulation rating for work on live or potentially live electrical equipment. Each piece is individually tested to ASTM F1505 standards for verified protection. Professional electricians and maintenance technicians are the primary users.

Dual-layer safety insulation

An orange outer insulation layer covers a yellow inner layer that acts as a visual wear indicator. If the yellow layer becomes visible, the socket has been damaged and must be replaced. This design supports sustained safety during repeated high-voltage tasks rather than single-use bursts. The insulation remains effective across the full working length of the socket.

Tested dielectric performance

The socket meets ASTM F1505 requirements for dielectric strength up to 1000 V. No moving parts or active cooling are involved, so operation is silent and power draw is zero. California Proposition 65 notices apply because the product contains listed chemicals. Buyers who need non-insulated impact sockets or larger drive sizes should select a different product.

Questions about this item

Does the orange and yellow insulation on this 20 mm socket degrade after continuous daily use?

The dual-layer insulation is individually tested to ASTM F1505 and rated for 1000 V protection; the yellow layer acts as a visual safety indicator so wear is immediately visible.

What drive tool must I already own to use this 12-point 20 mm socket?

A 1/2" drive ratchet or breaker bar is required; the socket’s 12-point opening fits standard 20 mm hex fasteners.

Will this 1000 V insulated socket fit on the same 1/2" drive tools I already use for non-insulated sockets?

Yes, it uses a standard 1/2" square drive, so it works with existing ratchets, extensions and torque wrenches of that drive size.
