Non-Insulated Step Down Butt Connectors - 12-10 to 16-14 AWG - 10 to 1000 Pack - Made in USA

Non-insulated step down butt connectors are engineered for reliable crimping when joining dissimilar wire sizes. Manufactured from high-conductivity copper (Alloy 110), these connectors feature seamless barrels and V-groove serrations to maximize contact surface and tensile strength. Electro tin-plating provides enhanced corrosion resistance, making them ideal for automotive, marine, and industrial electrical systems.
