Klein Tools 85073INS 3 Piece 1000V Insulated Heavy-Duty Screwdriver Set
The Klein Tools 85073INS 3-Piece Insulated Screwdriver Set functions as a dielectric electrical hand tool kit engineered to execute terminal screw driving and panel hardware installations near live electrical components. Rated for dielectric shock protection up to 1000V AC and certified to ASTM F1505-16(2021) and IEC 60900:2018 standards, this USA-made set features induction-hardened steel alloy shanks, dual-layer flame-retardant orange insulation, Cushion-Grip handles, and integrated handle tether holes. Outfitted with 4-inch round shanks in 1/4-inch Slotted, #2 Phillips, and #2 Square drive profiles, this 3-piece set enables electrical contractors to perform safe terminations inside commercial breaker boxes, control cabinets, and switchboards.
Best Used For:
- Commercial Breaker & Panel Termination: Driving terminal screws, neutral bars, and circuit breakers inside 1000V rated distribution panels.
- Elevated Overhead Electrical Installation: Connecting safety lanyards to the integrated handle tether holes when working on ladders or scaffolding to eliminate drop hazards.
- Energized Equipment Diagnostics & Maintenance: Executing component repairs near live electrical lines certified for shock isolation up to 1000V AC.
Key Performance & Safety Features
- 1000V Dielectric Safety Rating: Individually field-tested to surpass ASTM F1505-16(2021) and IEC 60900:2018 standards for live line shock protection up to 1000V.
- Dual-Layer Flame-Retardant Insulation: High-impact bright orange composite coating repels heat, prevents flashover, and guards internal steel shanks from mechanical strikes.
- Molded Structural Tether Hole: Integrated handle loop pass-through permits secure lanyard clipping for code-compliant tethering during overhead work at height.
- High-Torque Cushion-Grip Handles: Soft-touch rubberized handle overmolds absorb palm friction and maximize manual turning torque without hand strain.
- Tip-Ident Orientation Cap System: Permanent handle end-cap markings supply rapid visual drive profile identification inside packed tool bags.
- Induction-Hardened USA Steel Shanks: Heat-treated structural alloy steel core delivers exceptional torsional strength and tip wear resistance.

Pro-Tip: Inspect the dual-layer orange insulation on your Klein 85073INS screwdrivers before opening energized breaker panels. If the underlying white insulation layer becomes exposed through severe scraping, take the driver out of high-voltage service immediately to ensure 1000V shock protection is maintained.
