Klein Tools 662-4-INS – Frequently Asked Questions
1) Is the Klein 662-4-INS square drive screwdriver rated for live electrical work at 1000V?
The Klein Tools 662-4-INS is an insulated screwdriver built and tested to IEC 60900 and ASTM F1505, the two standards that govern 1000V rated insulated hand tools. The dual-layer molded insulation is flame retardant and impact resistant, and the Cushion-Grip handle is high-dielectric plastic. Inspect the insulation for nicks or gouges before each use, as those standards require.
2) Will a #2 square tip driver work on the Robertson screws in a panel or on receptacle terminals?
A #2 square (Robertson) tip is the standard size for the square-drive terminal screws found on most 15A and 20A devices and many panel lugs. The 662-4-INS carries a #2 square tip on a round shank. If your fasteners are #1 (smaller, common on light-duty devices) or #3, this driver will cam out or won't seat, and you need the matching tip size instead.
3) How deep can this insulated screwdriver reach into a recessed screw?
Shank length is 4 inches (10.2 cm) with an overall length of 8.313 inches (21.1 cm). On an insulated driver the insulation runs down the shank to near the tip, so the usable reach into a recessed or counterbored application is the shank length, not the overall length. For deep gear trays or recessed enclosure screws, a 4-inch shank is the working number to design around.
4) Will this Klein screwdriver hold the screw magnetically when working in a panel?
No. The 662-4-INS tip is non-magnetic, so it will not retain a loose screw for a one-handed start overhead or down inside a deep enclosure. If magnetic retention is what you need, pick a driver listed as magnetic. Insulated drivers are commonly non-magnetic, so check that line on any 1000V tool.
5) Is this the right tool to add to an electrician's 1000V insulated set, or do I need a full kit?
This is a single driver, one model, 662-4-INS, with a #2 square tip. It covers square drive fasteners only. A working insulated set for panel and control work typically also needs slotted and Phillips cabinet-tip drivers and insulated nut drivers in the same IEC 60900 / ASTM F1505 class. Buy this one to fill the square drive slot in a kit you already carry.
6) How do I tell this insulated Klein driver apart from a standard uninsulated one on the truck?
Look at the color: the insulation is coded red over a black Cushion-Grip handle, which is the visual tell for Klein's 1000V insulated line. The full part number is 662-4-INS, and the INS suffix marks it as the insulated version. A standard square drive driver without that coding is not rated for live work.
7) How durable is the shaft on this insulated square driver under real torque?
The blade is induction hardened steel, which is what keeps a #2 square tip from rounding over when you lean on a stubborn lug. Tool weight is 3.2 oz (91 g), so it rides easily in a pouch without adding bulk to a full insulated set.
