I have a problem that is both time-consuming and annoying. Often, I use Allen-head bolts for jigs and mounting tools. These screws with threaded inserts or tee nuts are quick, secure and strong. Is there a standard size for the recesses for various size bolts? If so, where can I find the list(s)? – James H. Anderson
Tim Inman: I know of no size standards for these. I always work backwards when using fasteners like this. First I get the fastener in hand, then I calculate the size holes needed, etc.
Chris Marshall: If you are talking about the sizes of recesses you need to bore to set the bolt heads below the surface of the wood, there are easy-to-find specs charts online for these Allen bolts or socket head cap screws (click here). Maybe some of our fellow eZine readers have favorite links to other specs charts they prefer instead. Please share!
