    18-8 Stainless Steel Square-Neck Carriage Bolts

    Image of Product. Back orientation. Carriage Bolts. 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.

    Image of Product. Front orientation. Carriage Bolts. Low-Strength Steel Square-Neck Carriage Bolts, Fully Threaded.

    Fully Threaded

    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.

    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.
