Facom Angled Open-Socket Wrench Set - 16pc (75.JE16) - deep recess at one end and open end socket at the other fit over protruding studs (6-point on both ends). The angle and through hole design accommodates threaded rods or a bar for extra leverage without affecting wrench strength. This is one of my favorite Facom products for field installations (cabinets, shelving, garage door track, etc).
Set includes - 8,9,10,11,12,13,14,15,16,17,18,19,21,22,23 & 24mm.
