Bendable design: can be bent into 90 degrees for access in tight spaces and precise probing during testing. Durable construction: made of cooper and stainless steel, with nickel plating on the surface for corrosion resistance and a long service life, delivering durable and reliable performance. Extra thin sharp tip: 0.7 mm needle tip is designed to be ultra thin and sharp, enabling nondestructive piercing of wire insulation. Wide compatibility: compatible with standard 4 mm Banana Plug Test Leads; fits with most test lead kits, diagnostic devices, and automotive testing and tools in the field. Practical use scenarios: Automotive diagnostics: probe wires in wiring harnesses and connectors without disconnecting components. Electronics : precisely probe signal lines on PCBs and tight cables. Field service and diagnostics: convenient for testing and diagnosing devices that use banana plug leads in the or on site.
