Gray Tools CHS7A-I 7 Piece SAE Nut Driver Set 1000V Insulated tool storage

7-Piece Insulated Nut Driver Set

This Gray Tools set contains seven SAE nut drivers ranging from 3/16 to 1/2 inch. Each driver is individually insulated and tested to ASTM F1505 standards for work up to 1000 V. The insulation uses an orange outer layer over a yellow inner layer that acts as a visual safety indicator. The set ships in a canvas pouch for storage and transport.

For Electrical Maintenance Professionals

Electricians and technicians working on live or potentially live equipment up to 1000 V will find the rated insulation and visual wear indicator essential for safety compliance. The SAE sizing covers common fastener sizes in North American electrical panels and enclosures. Buyers who need metric sizes or drivers without voltage-rated insulation should look at alternatives.

ASTM F1505 1000 V Rating

The decisive specification is the ASTM F1505 certification for 1000 V working voltage. This standard confirms each driver has passed dielectric testing and meets the insulation thickness requirements for electrical safety. The dual-layer insulation with the yellow indicator layer provides immediate visual confirmation that the protective barrier remains intact before each use.
