Nice case for a variety of screws, but most people work with 3/4 inch wood and I don't think the other variety of screws would be necessary. I myself usually worked with 1/2-3/4 inch plywood or hardwood so I only needed two sized screws. Would recommend you only buy the coarse screws...better bite and holding. The finer threaded screws recommended for hardwoods more likely to strip the work you're screwing into from personal experience.
