    Fully Threaded

    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.
    Zinc Flake Coated—Zinc-flake-coated steel bolts are 40 times as corrosion resistant as zinc-plated bolts and comparable to Magni-coated bolts.

    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).

    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.
