After many, many weekends, I began assembly on my current project. I was driving 3″ #10 screws by hand. The holes were predrilled for the screws. After several screws, one of them sheered in half with little or no warning. The legs that were supposed to be able to be taken apart for moving are now permanently joined.
The screws were purchased at Home Depot. Just a standard flat top phillips head wood screw, manufactured in China.
Question: How can I be assured that the fasteners I’m using are decent quality?
