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.

Low-Strength Steel Knurled-Neck Carriage Bolts
Fully Threaded
Partially Threaded
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.
