5/16" 12-Point Insulated Socket

The Gray Tools T10-I is a 5/16 inch 12-point socket built for 3/8 inch drive tools. It carries a 1000 V insulation rating for work on live or de-energised electrical systems. Electricians and maintenance technicians use it where shock protection is mandatory. The socket meets ASTM F1505 test requirements for insulated hand tools.

Dual-Layer Insulation and Drive Fit

An orange outer insulation layer covers a yellow inner layer that acts as a visual wear indicator. Damage to the orange layer reveals the yellow beneath, signalling that the socket must be replaced. Each piece is individually tested before it leaves the factory. The 12-point drive engages fasteners at multiple angles, reducing rounding on stubborn bolts.

Upgrade from Uninsulated Sockets

This socket replaces standard chrome or impact sockets when voltage exposure is a risk. The jump is worth it whenever work procedures require verified 1000 V protection and a visible safety check. It is not suited for buyers who need larger drive sizes or hex dimensions outside the 5/16 inch specification.
