Countersunk Washer 2.5 to 4 mm SP

thingiverse

Proposed Special Washer, This washer was created to bypass tiny wooden countersunk screws, measuring 2.5 mm to 4 mm, as they pass through large drills. It also functions as a spring that bends inside the hole. In low-cost IKEA furniture, this indicates when the maximum torque has been reached without breaking the wood. This part is part of a set designed to integrate IKEA furniture with budget shelving systems.
