Medium-Strength Metric Class 8.8 Steel Square-Neck Carriage Bolts
 |  |
Fully Threaded | Partially Threaded |
These Class 8.8 steel bolts are suitable for fastening most machinery and equipment. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Length is measured from under the head.
Zinc Yellow-Chromate Plated—Zinc yellow-chromate plated steel bolts resist corrosion in wet environments.

18-8 Stainless Steel Square-Neck Carriage Bolts
 |  |
Fully Threaded |
Made from 18-8 stainless steel, these bolts have good chemical resistance and may be mildly magnetic. They're a good choice for ACQ-treated (arsenic-free) lumber. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Length is measured from under the head. Dimensions meet ASME B18.5 or DIN 603 specifications. Some also meet ISO 8678. DIN 603 is functionally equivalent to ISO 8678 with slight differences in head diameter, head height, and length tolerances.
Match the thread spacing of mating components.
Coarse Thread—Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.

Highly Corrosion-Resistant 316 Stainless Steel Square-Neck Carriage Bolts
| |
Fully Threaded |
More corrosion resistant than 18-8 stainless steel bolts, these 316 stainless steel bolts have excellent resistance to chemicals and salt water and are a good choice for ACQ-treated (arsenic-free) lumber. They may be mildly magnetic. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Dimensions meet ASME B18.5 or DIN 603 specifications. Length is measured from under the head.

Stainless Steel Square-Neck Elevator Bolts
 |  |
Made from stainless steel, these chemical-resistant bolts have a square neck that keeps them 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.

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

About half the strength of medium-strength bolts, these steel bolts are good for light duty applications. They 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. A square neck keeps these bolts from turning when tightening a nut. Zinc plating provides corrosion resistance in wet environments. Length is measured from the top of the head.

Low-Strength SAE Grade 2 Steel Fanged Elevator Bolts
 |  |
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.
