Dexter K71-G03-11 Trailer Lug Bolts, 1/2 Inch Grade 5, Set of 5

The Dexter K71-G03-11 is a set of five 1/2 inch trailer lug bolts used to secure a trailer wheel to the hub. Each bolt is manufactured from Grade 5 carbon steel with a black oxide finish for corrosion resistance, and features a hex head for use with a standard socket or lug wrench. The bolts have a 0.5 inch diameter with UNC (Unified National Coarse) right-hand threads, thread class 3A, and are single-end threaded for installation into the wheel hub. This lug bolt set is intended for upkeep and repair of trailer wheel hardware, replacing worn, corroded, or damaged bolts to keep wheels properly and safely fastened. The Grade 5 hardness rating provides a higher clamping strength than standard-grade fasteners, making it suitable for the repeated torque loads a trailer hub experiences on the road. Sold as a set of 5, the K71-G03-11 provides enough bolts for one full wheel on most standard trailer hub patterns. This product is part of Dexter's trailer hubs and bearings hardware line.
