3M Hook Terminal allows terminal to wrap around a portion of a free-standing stud for a secure and reliable connection. The terminal has a nylon-insulated, butted-seam barrel and withstands temperatures of -40 to 221 degrees F (-40 to 105 degrees C). Electrolytic copper construction offers good conductivity and a tin-plated finish resists corrosion.3M Hook Terminal is color-coded for quick and easy identification of the wire size required. The funnel-designed, seamless brass sleeve guides the wire into position while providing electrical contacts and mechanical stress relief at the point of insulation. The abrasion-resistant, flared, nylon-sleeve insulation ensures positive grip and has a stepped design for mistake-proof crimping. UL Listed, CSA Certified and RoHS 2011/65/EU Compliant.
