This article on woodscrews and bolts is very basic at the moment but may get improved with time.
Coach Screws and Bolts have been used in the construction and erection of my shed as mentioned in my post about Securing Shed Doors.
Woodscrews Which Don’t Split Wood
This link goes to Titan Metal Werks, Inc of Illinois, USA a company which makes SplitStop screws which they claim won’t split the wood they are screwed into. Designed for fixing decking they appear to drill themselves in and make a countersunk hole to boot.
See their example video which I have embedded below. It shows how an ordinary screw splits the wood when it is screwed in. Then it shows how their screws can be screwed in around it, very close to the edge, without splitting the wood:
This is what TITAN have to say about their products:
“Experience the ability to place woodscrews within 1/8″ of the edge of a board without splitting the wood. Install deck boards and railing balusters with little fear of splitting! Penetrate knots without shearing-off screw heads! Countersink effortlessly, even in Oak! All without predrilling!” — Titan
