Built for dialing in swimbaits and adding weight to finesse soft-plastics, theNako Tungsten Nail Weightsare made with 97% pure tungsten for a 50% smaller profile when compared to traditional lead nail weights. Eco-friendly and perfect for use in fisheries that have banned lead, the Tungsten Nail Weights increase sensitivity and allow vibrations to be transferred up the line to enhance angler feel of subtle bites and bottom contact. Ideal for Neko rigs, hover rigs, and adjusting the sink rate for soft plastic swimbaits, the Nako Tungsten Nail Weights utilize a pagoda-style shape that s designed to easily insert and grab the inside of soft plastics to securely stay in place during every cast.
