Baling wire and lockwire tie together or tie down items to secure and support them. Wrap these flexible wires around items and twist the wire ends together for a tight hold. Baling wire, sometimes called bale wire, is used in a range of applications from bundling sheets of cardboard to mending fences. Spools of baling wire are commonly used with an automatic baler. Bale ties are often used for manually tying off bales from baling presses. Lockwire, also known as safety wire, anchors the head of a bolt or screw to a surface or another fastener to help prevent loosening due to vibration.
