This type...
I've been whaling away on the pin, and it's just not going fully in. They're big buggers - the hole is 19mm - and, yes, it's the right size drill bit for the fasteners, which came with a (new) two-post hydraulic lift that I'm installing into the new garage.
I'd say they're probably 50% of the distance between gently resting in the bolt, and fully home. They feel solid - I don't think there's any way I can get 'em out again to run the drill down again. They all just dropped straight home, no resistance. I'm using a decent size lump hammer, nothing massively heavy, but the biggest I've got.
Are they OK like that, so long as they are PROPERLY belted?
Do I need to just man up a bit, and make sure I get 'em fully home and expanded, come what may, no matter what size hammer it takes...?
