No-square carriage bolts are particularly useful in non-structural applications where aesthetic considerations are important. For instance, they are commonly used in furniture construction, where the appearance of the bolt head is more prominent. Similarly, these bolts are advantageous in outdoor furniture or garden projects, where ease of installation and corrosion-resistant materials are paramount.

A carriage bolt, also known as a round head square neck bolt, is designed to be used in wood, metal, and other materials. Its distinguishing feature is the rounded head that helps to provide a low-profile finish when installed. The square neck below the head prevents the bolt from turning when a nut is tightened, making it an ideal fastener for a wide array of applications. Carriage bolts are typically used in situations where a smooth finish is required, and they can easily be installed with just a screwdriver and a wrench.

A hex nylock nut, also known as a nylon-insert lock nut, is a type of hex nut with a nylon insert at the top of the threads. The nylon insert serves as a locking mechanism, providing resistance to loosening caused by vibration and torque. Hex nylock nuts are commonly used in applications where secure fastening and resistance to loosening are essential, such as automotive, machinery, and equipment assembly. These nuts offer a reliable and cost-effective solution for preventing unintended loosening of fasteners in critical applications.
