    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.

    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.
