Made of high quality steel (chrome-molybdenum); thorough and exact heat treatment insures the correct balance of strength and durabilityEngineered specifically for use with impact tools, using the most up to date industrial specificationsMade to transfer the pressure from the thinnest part of the socket wall toward the thicker section, resulting in increased strengthPackaged in a metal caseLifetime WarrantyThis standard length fractional impact socket set features our high torque drive. This limits the amount of wear on the corners of the fastener and the socket. It also improves the strength of the socket, transfers increased torque to the fastener and allows easier access to tight areas.
