Basically what you're getting is a pair of locking pliers that actually stay locked under heavy torque, even when you're working on stubborn bolts or structural steel, and the serrated jaws bite into smooth surfaces without slipping—most guys I've dealt with on job sites swear by the 7-inch for framing work, it's the sweet spot for and reach.

The whole body gets heat-treated, not just the jaw, and then they do an induction quench on the jaw itself, which is why the serrations hold their edge after clamping onto rusted rebar or hardened nuts; you'll see the rivet construction on every model, and it distributes force way better than the pinned ones you get in cheap sets, give or take 20% more clamping presure.

5-inch is basically a precision tool for tight spots like HVAC or electrical panels, the 10-inch is for heavy demolition or pipe work where you need brute force, and the 7-inch fits somewhere in between—also, we don't recommend these for soft materials like aluminun or plastic since the serrations will mar them pretty badly.

You can order them in either nickel-plated or black oxide, and the black oxide holds up better if you're working in humid conditions (usually 2-4 weeks lead time on that finish), but the nickel is what most production shops go with because of that it's easier to spot on a cluttered bench.

For packaging we've got bulk if you're just stocking the shop or retail blister packs if you're reselling—either way, the MOQ is 50 units per size, and we'll send you a COA with HPLC data on materail composition so you know the Cr-V content is within spec.

The screw adjustment mechanism is pretty straightforward—just turn the knob to set the jaw opening, no fumbling with gears or levers—and the PVC handle option actually adds about 1.5 ounces but reduces vibration fatigue if you're using them all day, something teh buyers who only spec the bare handles usually don't think about until their hands cramp up.
Nickel plated gives you a shiny, corrosion-resistant surface that's easier to clean, while black oxide offers a matte finish with some rust protection and better grip in oily conditions. Both are durable, but pick based on your work environment.
Yes, we can mix sizes in bulk orders, but the MOQ is typically 500 pieces per shipment. Let us know the quantity per size, and we'll confirm pricing.
Yes, we can provide mill certificates for the steel and hardness test reports upon request. Just let your sales contact know what you need when placing the order.
The PVC handles are dip-coated onto the steel, so they're not designed to be removed. But they're pretty tough—if one does wear out, you'd need to replace the whole plier.
For retail, each plier goes into a color box or blister card with a barcode, and we can customize the packaging with your logo. Bulk packing means they're just loose in a carton, which saves on cost.
