I have concluded that the surface-mounted tee-nuts (item 94122A200 from McMaster-Carr) are difficult to break, but they do break at the collar if you tighten their mating bolts too much.
So I removed these 14 tee-nuts from my knockdown Nicholson bench. When it comes to a workbench, nothing should be light- or medium-duty. I replaced them with an old standby for me: the six-prong steel tee-nut for wood, also from McMaster-Carr (90975A163).
These are less expensive – $13.72 for a pack of 50 – and can be tightened with prejudice. You’ll crush the wood before you strip or break these tee-nuts. The downside? They will sometimes fall out when your parts are disassembled.
And here ends the great surface-mounted tee-nut experiment of 2014.
Tomorrow I’ll finish up this workbench – flatten the benchtop and install the crochet. I’ll also shoot a video of how the bench knocks down for travel. I am pleased with the way it goes together.
Then I’ll get back on a pair of Roorkee chair commissions.
