Using this Klein broad head bull pin is straightforward. When working at height, use the tether hole to attach a tether for safety. Align the pin with the holes you need to work on, and thanks to its design, it won't easily slip from your hand. If the pin gets wedged, you can use a wrench on the squared - off shoulders below the head to loosen it. As for maintenance, keep it in a dry place to prevent rust. The black oxide finish gives it some rust resistance, but it's still a good idea to wipe it down after use. Don't use it in extreme conditions that could damage the heat - treated alloy steel. If you notice any signs of chipping or excessive wear, it might be time to replace the pin.
