Using the Klein Tools JTH9E17 is easy. First, select the right size hex key according to your fastener. The laser - etched sizes on the blade make it simple to pick the correct one. Insert the hex key into the socket of the fastener and use the T - handle to turn it. The soft - touch grips will give you a comfortable and firm hold. When using, make sure the key is fully inserted to avoid stripping the socket. As for maintenance, since the steel is treated to resist rust and corrosion, you just need to keep it clean after use. You can wipe it with a dry cloth. Hang it up using the convenient hang hole to keep it organized and prevent damage.
