    Made from Grade 5 steel, these 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. Grade 5 steel bolts are marked with three radial lines. Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.5 specifications. Length is measured from under 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.

    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.

    About half the strength of medium-strength bolts, these Grade 2 bolts are for light duty fastening. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Material meets ASTM A307 or SAE J429 specifications for quality. Dimensions meet ASME B18.5 specifications. Length is measured from under the head.
    Zinc Plated—Zinc-plated steel bolts resist corrosion in wet environments.
    Hot-Dipped Galvanized—Hot-dipped galvanized steel bolts have a thick coating for better corrosion resistance than zinc-plated steel bolts. They meet ASTM A153 specifications for quality of hot-dipped coatings. They’re a good choice for ACQ-treated (arsenic-free) lumber. Bolts must be used with hot-dipped galvanized steel nuts (sold separately).

    These bolts have a thicker, domed head that provides greater wear resistance than flat head bolts. Used on heavy equipment, such as plows, these bolts are angled under the head to sit nearly flush within countersunk holes. A square neck keeps them from turning when tightening a nut. The zinc yellow-chromate plating provides corrosion resistance in wet environments. Material meets SAE J429 specifications for quality. Length is measured from the base of the oval top. Head height includes the neck and oval top.

    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.

    Used on heavy equipment, such as plows, these bolts have a smooth, flat head that's angled underneath to sit flush within countersunk holes. A square neck keeps them from turning when tightening a nut. The zinc plating provides corrosion resistance in wet environments. Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.9 specifications. Length is measured from the top of the head. Head height includes the neck.

    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.
