These cotter pins from the Fasteners section of Industrial and Scientific proved to be very useful in various DIY projects. As my tests showed they are durable enough to withstand heavy-duty applications. The assortment contains various sizes and shapes, making it easier to find the right fit. However, the packaging could be improved as the pins were scattered inside the plastic container .Overall, a great value for the price and highly recommended for anyone who needs versatile and sturdy cotter pins..
