Hillman's Exterior Black Coated Carriage Bolts, an essential component of their Exterior Black Fasteners line, ideal for robust outdoor constructions. These carriage bolts are characterized by their unique domed or countersunk head and a square underhead neck, which makes them particularly useful in situations where the bolt head must not protrude for safety or aesthetic reasons, such as on decks or playground equipment.
The standout feature of these carriage bolts is their protective black coating, which offers tenfold the corrosion resistance compared to standard zinc-coated bolts. This formidable protection is particularly critical in outdoor settings where the elements can be unforgiving, ensuring the bolts withstand rain, snow, and other harsh conditions without succumbing to rust.
Moreover, the aesthetic advantage of the black coating cannot be overstated. It provides a sleek, uniform look that complements any wood color, enhancing the visual coherence of the construction. Whether it's for a wooden bench or a garden pergola, these carriage bolts ensure the hardware becomes a part of the design, rather than just a necessity.
Hillman's commitment to compatibility and safety is further evidenced by the ACQ approval, indicating these carriage bolts are suitable for use with treated lumber, avoiding the chemical reactions that can lead to degradation or failure of the fasteners.
The Exterior Black Coated Carriage Bolts are available in various sizes to match different project demands, providing a reliable and visually appealing fastening solution for a wide range of outdoor woodworking projects. These bolts are designed not just to meet the functional requirements of strength and durability but also to enhance the finished look of any structure they are used in.
