Pliers gripping issue? My lineman's keep slipping on bolts - need help!

Hey guys, I'm on a tight budget and got a pair of lineman's pliers from HF about a year ago. Lately they've been slipping when I try to grip bolt heads. The jaws look fine but they just don't bite like they used to. Any cheap fixes? Or do I need to replace them? I'm not looking to spend a lot. Thanks!

Dude, I had the same issue with a cheap pair! Before you toss 'em, try cleaning the jaws with a wire brush and some alcohol. Sometimes gunk builds up and makes them slick. Also, check if the pivot is loose—if so, you can tighten it with a hammer and punch. But honestly, if they're from HF, they might just be worn out. For a budget option, try the Knipex Cobras? They're pricey but last forever. Or check garage sales for old US-made pliers!

Slipping on bolts? That's a sign of worn teeth. Lineman's pliers aren't really meant for bolts anyway—you want a proper wrench or socket. But if you must use pliers, get some with hardened teeth. Cheap ones lose their bite fast. I'd recommend measuring the jaw gap with calipers to see if they're worn unevenly. If they're off by more than a few thousandths, they're toast. Also, consider a pair of Knipex TwinGrip—they grip rounded bolts like nothing else. Not budget, but you get what you pay for.

I've had good luck with Channellock pliers for a mid-range price. They're not as cheap as HF but way better quality. For your current pair, try a trick: put a piece of sandpaper in the jaws and grip the bolt—the grit gives extra bite. Works in a pinch. But if you're doing a lot of bolt work, invest in a decent adjustable wrench. Pliers are for twisting wire, not turning bolts. Just my two cents from years of renovating.

Thanks for the tips! I'll try the sandpaper trick and cleaning first. If that fails, I'll look into Channellock. I do use them for bolts sometimes because I'm lazy, but I guess I should use the right tool. Appreciate the help!
