Key-Locking-Neck Flat-Head Plow Bolts
 |  |
Partially Threaded |
Also known as reverse-key plow screws and bucket-tooth bolts, these bolts have a locking key that keeps them from turning when tightening a nut. Often used on heavy equipment, such as plows, they have a smooth, flat head that's angled underneath to sit flush within countersunk holes. Material meets SAE J429 specifications for quality. Length is measured from the top of the head.
