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.
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.
