    Medium-Strength Grade 5 Steel Knurled-Neck Carriage Bolts

    Image of Product. Front orientation. Carriage Bolts. Medium-Strength Grade 5 Steel Knurled-Neck Carriage Bolts.
    Image of Product. Back orientation. Carriage Bolts. Medium-Strength Grade 5 Steel Knurled-Neck Carriage Bolts.
    Made from Grade 5 steel, these bolts are suitable for fastening most machinery and equipment and are zinc plated to resist corrosion in wet environments. A knurled neck grips the inside of the hole to keep them from turning when tightening a nut. A smooth, rounded head provides a finished look. Grade 5 steel bolts are marked with three radial lines. Material meets SAE J429 specifications for quality. Length is measured from under the head.

    About half the strength of medium-strength bolts, these bolts are for light duty fastening. The zinc plating provides corrosion resistance in wet environments. A knurled neck grips the inside of the hole to keep them from turning when tightening a nut. A smooth, rounded head provides a finished look. Material meets ASTM A307 and SAE J429 specifications for quality. Length is measured from under the head.

    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.

    Low-Strength SAE Grade 2 Steel Ribbed-Neck Elevator Bolts

    Image of Product. Front orientation. Elevator Bolts. Ribbed Neck.
    Image of Product. Back orientation. Elevator Bolts. Ribbed Neck.
    Ribs under the head dig into the surface of soft metal and plastic to keep the bolt from turning when tightening a nut. These bolts are commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, because the smooth, low-profile head provides a flush fit when installed. Length is measured from the top of the head.
    Black Oxide—Black-oxide steel bolts are mildly corrosion resistant in dry environments.
    Zinc Plated—Zinc-plated steel bolts resist corrosion in wet environments.
