Question I did a test drilling of a #10x3 decking screw into a tree stump, no problem. I predrilled holes in an old wood table top. I put the tabletop on top of the tree stump, started the screws but after about 2/3 of the way in using my electric drill I heard a squealing noise, the screws stopped going in, and now I have just over an inch of the screw sticking up and cannot get it to go further or get it out. Any suggestions? Thanks so much.
Answer The squeal is a sign of friction/tightness....To start with check the hole size...for a pilot hole it need to be the same as the 'core' thickness, but less than the threads. Yo need to drill as deep as you can but just short of the length of the screw. The other tips I have use is working the screw, when it's goes tight like that, then undo it not completely the tighten it up, sometime I have used ptfe spray, or lubricate on the screws but more important I use spax, or similar type screws, and they are usually hassle free visit; http://www.axminster.co.uk/product-Spax-Spax-Premium-Quality-Wood-Screws-19751.h...
