Fasteners, screws, and nails are three of the basic necessities for household maintenance. And just keeping them in storage is definitely not enough. They need to be organized so that they can be easily found and use whenever maintenance emergencies arise.
Organizing these small entities in just any way will not prevent one from making mistakes of distinguishing one from the other. But by applying simple ergonomic concepts in organizing these small entities can result to faster search and prevent mistakes such mismatching.
Firstly, group the fasteners, screws, and nails according to wood, cement and plastic. After grouping, arrange them accordingly in a container with multiple bins. Next, within each group, assign each entity on a bin in a manner that you avoid putting similarly colored and shaped ones next to each other. As much as possible, two adjacent bins should have two entities that have contrasting colors and/or obviously different shapes. After grouping and assigning them to the bins, put flags or notes to indicate the wood, cement, and plastic grouping. And for ease of searching, position the storage container in a slanting position such that the user can easily see the bins and their contents without having to lean forward. Ergonomically speaking, color contrast helps the eyes in differentiating things better, ergo making the search process faster. And for more ergonomic benefits, the slanting position prevents hand, neck, and back strains when searching the container.
