Made from Grade 5 steel, these bolts are suitable for fastening most machinery and equipment. They have a smooth, low-profile head that provides a flush fit when installed. They're commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, but can also be used in leveling and work-holding applications. A square neck keeps these bolts from turning when tightening a nut. They are zinc yellow-chromate plated to resist corrosion in wet environments. Grade 5 steel bolts are marked with three radial lines. Length is measured from the top of the head.

Made from 18-8 stainless steel, these bolts have good chemical resistance and may be mildly magnetic. A square neck keeps these bolts from turning when tightening a nut. They're 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.

Sharp teeth bite into the surface of wood, rubber belting, and other soft materials 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.

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. The zinc plating provides corrosion resistance in wet environments. Length is measured from the top of the head.
