Immortan D Posted January 18, 2016 Report Share Posted January 18, 2016 I've been using threaded inserts a lot on my woodworking jigs, mostly EZ inserts but also t-nuts on occasions. The sizes I use the most are 1/4", 5/16" and 3/8". Now earlier today, I was reading the "Complete Vise Instructions" manual for the Benchcrafted Classic Leg Vise (available from this page) and at page 12 I found this: The holding power of machine screws in wood is about the same as using a threaded insert, and you don’t have to buy the inserts. It’s also a great technique for making jigs and knock-down joints. Thoughts? Is it really "about" the same? Should I stop buying threaded inserts and use taps to thread the holes instead?

..Kev Posted January 18, 2016 Report Share Posted January 18, 2016 Depends on what you're threading? I'm sure that BC is referring to hard wood and not plywood.. Quote Link to comment Share on other sites More sharing options...
rodger. Posted January 18, 2016 Report Share Posted January 18, 2016 I use a 1/4-20 tap on my ZCIs and insert threaded jobbies to level the plate with the saw table. Works great! I use solid wood for my inserts, about 1/2" thick. Quote Link to comment Share on other sites More sharing options...
Tpt life Posted January 18, 2016 Report Share Posted January 18, 2016 Threaded inserts for knockdown are more about repeated insertion and removal. Machine screws in wood are best for installation that is left in place. This seems at odds with the way the blue reads in your post. 1 Quote Link to comment Share on other sites More sharing options...

But decided to post it here because I could've been wrong and wasting my money on inserts. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted January 18, 2016 Report Share Posted January 18, 2016 You could drill and tap the wood then drip a little epoxy in the hole and let it dry. Re drill and tap would yield much stronger threads. 2 Quote Link to comment Share on other sites More sharing options...

The BC leg vise plans (as outlined in blue) are only refering to the vice install. Knock down hardware for legs and stretchers have included barrel nut.

RichardA Posted January 18, 2016 Report Share Posted January 18, 2016 If you're going to thread wood, it better be a damn hard wood.. otherwise the stress of any movement will over time loosen and weaken that connection! Quote Link to comment Share on other sites More sharing options...
