Rockler Thread Detective
Finding correct sized and threaded screws and bolts is very trying. I salvage most parts and throw in a parts bin. Finding the correct bolt for a project is difficult. These sets of Thread Detectives may be of help. If one has a bolt to match maybe he/she can assure a match by enlisting the aid of these ---
