Klein Tools H80718 – Frequently Asked Questions
1) Will a straight-claw hammer pull NM-B (Romex) staples without nicking the cable?
That's exactly what the straight claw on the Klein H80718 is for. The claw slides flat under a staple leg, which a curved claw can't do against a stud face, so you can lift the staple straight out. Work it under the staple edge and pull with steady pressure rather than snapping it back, and the sheathing stays intact. It's an 18 oz forged steel head, so you have enough mass behind it to seat the claw and still drive box nails on the same rough-in.
2) Is an 18 oz hammer heavy enough for framing, or should an electrician carry something bigger?
Eighteen ounces is the middle ground. The H80718 head weighs 18 oz on a 14.8 inch overall length, which drives box nails, mounts device boxes and sets conduit straps all day without wearing your arm out. For repetitive full-size framing nails a 20 to 22 oz framing hammer with a longer handle swings faster; for electrical rough-in, panel work and HVAC duct support, 18 oz is the weight most trades actually carry on the belt.
3) Fiberglass or wood handle hammer for daily electrical work?
The Klein H80718 uses a high-strength fiberglass core handle, 13 inches of handle under a 14.8 inch overall length. Fiberglass won't dry out, swell or loosen at the eye the way a wood handle does after a season in a truck, and the core soaks up more of the shock that a wood or solid steel handle passes into your wrist. Wood is still the cheaper thing to rehandle if you break one; fiberglass you replace as a unit. The grip is a non-slip surface in orange and black, so it's easy to spot on a dark rough-in floor.
4) Can the Klein H80718 hammer be tethered for work at height?
There's an integrated hang hole in the handle for tethering, so it can be tied off for fall-protection on lifts, scaffold and ladder work, and hung on a belt or rack the rest of the time. The tool weighs 1.8 lbs complete, which is the number your tether and anchor rating has to cover.
5) Will a smooth-face hammer mar trim and finished surfaces?
The H80718 has a smooth face, 1.1 inches across, which is what you want anywhere the work shows. A milled or waffle face grips a framing nail better but stamps a pattern into anything it touches and chews up cover plates and trim. Smooth face plus 18 oz is the combination for finish-adjacent work: device boxes, cover plates, mounting hardware, duct hangers.
6) Is this hammer insulated or rated for live electrical work?
No. The H80718 is a general-purpose striking tool with a forged steel head and a fiberglass core handle. Fiberglass is not an insulation rating, and the head is bare steel, so treat it as a standard hammer and de-energize before working. If you need dielectric protection, look for tools carrying an explicit insulated rating rather than relying on handle material.
7) Will an 18 oz Klein hammer fit in a tool pouch or bucket rather than a hammer loop?
It measures 14.8 inches overall with a 6.3 inch head, and the whole tool is 1.8 lbs. That's shorter than a framing hammer, so it drops into a bucket organizer or bag pocket and rides on a belt loop without swinging into your knee on a ladder. Full stated envelope is 14.8 x 6.3 x 1.2 inches.
8) What model number do I order for the Klein 18 oz straight-claw fiberglass hammer?
Klein Tools H80718 is the part number, and it's a single configuration: 18 oz forged steel head, fiberglass handle, straight claw, smooth face. No handle-length, finish or face options to specify, so one line item covers it. Standardizing a crew or a facility MRO crib on one number is straightforward here for that reason.
