Overview
The Klein Tools KNECT Quad-12 Heavy-Duty Impact Flip Sockets, Metric, 6-Piece (653MQS) is the complete Quad metric set. This is an impact flip socket set designed for driving metric fasteners from 7 mm to 19 mm with an impact driver or KNECT hand tools, using three color-coded quad sockets in a MODbox storage case.
Sizes are split into three sockets: small covers 7, 8, 10 and 12 mm; medium covers 9, 11, 13 and 14 mm; large covers 15, 16, 18 and 19 mm. That is twelve metric hex sizes in a case under 7" long.
Every socket uses the same spring-loaded nesting. The smaller hex compresses out of the way when you press it onto a larger fastener, and flipping the socket gives you the other pair. Painted, industry-standard color rings speed up size identification.
The set includes dual extension shafts. The small and medium quad sockets store on the 6-1/2" extension shaft for quick size transitions. A multi-purpose adapter works with KNECT (M) pass-through socket wrenches and screwdrivers, so the sockets work by hand as well as on an impact. Klein lists 1/4" and 3/8" drive sizes across the set.
Storage is a MODbox case with a small parts tray for bits and fasteners, stackable with other MODbox cases. It measures about 6-15/16" x 3-11/16" x 1-13/16" (17.7 x 9.4 x 4.6 cm). Sockets are heat-treated cold forged steel with a manganese phosphate finish.
Who should buy it: maintenance techs, mechanics and service crews who want full 7-19 mm metric coverage for an impact in one small case, especially those already using MODbox storage or KNECT tools.
