Strong plastic construction provides a durable, lightweight measuring tool that is easy to handle and safe for delicate parts. The plastic design helps prevent damage to soft or finished surfaces while offering reliable basic measurements. Plastic ruler with twoway measurement offers internal and external measurements on a clear metric scale. This twoway capability enables quick checks of both external dimensions and internal gaps, making it versatile for small parts and assemblies. Plastic caliper with metric features step and depth measurements. Includes a depth measurement capability and stepped/ groove measurement to handle varying profiles. This micro caliper tool is designed for compact spaces and precise readings. Size and compatibility: compact, lightweight design suitable for portable use in workshops, hobby setups, and fieldwork. The metric scale supports common measurement tasks in electronics, model making, jewelry, and small hardware. Performance attributes: easy to read scale, smooth sliding rales, and reliable repeatable measurements for basic to intermediate tasks. The plastic construction provides a balance between durability and cost efficiency. Use scenarios: Electronics and model making: quickly measure small enclosures, connector openings, and component heights to ensure proper fit. Jewelry and crafts: measure ring shanks, bead diameters, and depth of slots or grooves for precise assembly. Small hardware and woodworking projects: check external diameters of pins, dowels, or screws and assess recess depths or step features in components.
