TeacherGeek Accessories - #10 Fender Washer - Pack of 200

TeacherGeek's #10 Fender Washers are wide, flat washers designed to help distribute the load of a screw or bolt more evenly, preventing damage and increasing the stability of connections in STEM construction projects. With a broad surface area and a central hole sized for #10 hardware, these washers are perfect for use with dowels, screws or bolts, especially when building structures that need reinforced fastening or smooth rotational movement. Their utility in both prototyping and finished designs makes them a versatile asset in the classroom or makerspace.

These washers are frequently used in engineering activities where components must pivot or remain secure under stress. For example, when placed between a moving part and a wooden surface, the fender washer reduces friction, allowing smoother motion and less wear. It can also stop bolts from pulling through soft materials like balsa wood, cardboard or foam board.

Educational Benefits

• Demonstrates fundamental mechanical engineering concepts such as friction, load distribution, and torque.
