These are commonly referred to as spring bolts, suspension bolts, or knurled bolts. The term “knurled bolt” comes from the characteristic ridged or serrated section, called a “knurl”, located just under the bolt head. This knurled section is designed to “seat” or “bite” into the hanger and shackles during installation. This prevents the bolt from rotating or spinning once it’s torqued down. This added grip reduces wear from vibration and movement over time and keeps your suspension components aligned and reduces wear from vibration and movement over time. Made from durable, corrosion-resistant materials, these bolts are ideal for light duty trailers, including utility trailers, campers, boat trailers, and small equipment haulers. These bolts are available in multiple lengths and with or without grease fittings. For a secure, long-lasting suspension system, trust the experts and choose bolts built for the road ahead. These critical fasteners are used to attach leaf springs to trailer hangers and equalizers, playing a key role in your trailer’s ride stability and safety.
