Klein Tools BD306 – Frequently Asked Questions

1) Is the Klein 5/16-inch keystone screwdriver safe to use on live electrical circuits?
No. The BD306/BD308 keystone screwdriver is not insulated and will not protect against electrical shock, so keep it off energized work. If you need to work live, order a Klein insulated screwdriver instead. The chrome-plated shaft and steel construction here are for corrosion resistance and strength, not dielectric protection.
2) What shank lengths does the Klein 5/16-inch keystone screwdriver come in, and which part number is which?
Two lengths: a 6-inch shank as BD306 and an 8-inch shank as BD308. Both carry the same 5/16-inch (7.9 mm) keystone tip, so pick on reach. The 8-inch gets you into recessed panel screws and deep boxes; the 6-inch is easier to control in a crowded enclosure.
3) Can I put a wrench on the shank of this Klein screwdriver for extra turning force?
The shank is square, which lets you get an open-end wrench on it for added leverage on stubborn slotted screws. Klein also builds internal flanges into the handle as a twist-resistant shaft anchor, and the oversized Comfordome handle is 35 percent larger than comparable handles for up to 50 percent more power. What it is not rated for is prying or chiseling.
4) What is the difference between a keystone tip and a cabinet tip screwdriver?
A keystone tip flares out wider than the shank at the blade, which gives more bearing surface in the screw slot and more torque tolerance. That flare is why it will not drop into a counterbored or recessed hole the way a cabinet tip (parallel-sided blade) will. This Klein driver is keystone with a 5/16-inch tip, so for deep-set or recessed slotted screws you want a cabinet-tip driver instead.
5) Does the Klein BD306 keystone screwdriver meet ASME/ANSI tool specs for institutional tool cribs?
It meets or exceeds applicable ASME/ANSI specifications and is made in the USA, which covers the usual domestic-preference and tool-standard language on government and institutional purchase orders.
6) Will this screwdriver hold screws magnetically?
No, the tip is not magnetized. Nickel-chrome precision-forged and polished blades with black tips, but no magnetic hold, so overhead or one-handed screw starts need a holding driver or a bit of tape.
7) What is the handle made of and what does it look like, so I can match the rest of my Klein set?
Plastic Comfordome handle, catalogued as yellow, described as tough amber and smooth so it seats in the palm. It is the oversized Klein handle profile, 35 percent larger than comparable screwdriver handles, so it will stand out next to standard-diameter drivers in the same roll.
