Apex MSF-21MM15 Metric Hex 6-Point Surface Drive Fixed Magnet 1/2" Square Drive 21 mm Power Socket

• Tool Side - Drive Size: 1/2" Square Drive
• Fastener Side - Drive Size: 21 mm Hex Socket
• Overall Length (OAL): 1.5" (38mm)

Features

• Impact Rated; Meets or Exceeds Proof Torque Requirement for Impact Standard ASME B107.112
• High-Carbon Alloy Steel and Proprietary Heat Treat Process Yields Greater Strength and Longer Life
• Cutting-edge Machining Process Allows Apex to Meet or Exceed Licensor Standards, Resulting in Tighter Tolerances and Superior Product Consistency
• Better and More Consistent Fit to Fasteners Leads to Better Torque Transfer
• Surface Drive- Large openings on the six corners of the hex end opening create a "floating" action that allows teh socket to slip quickly and easily onto the nut or bolt. Ideal for compensating for imperfect alignment between the tool and fastener.
• Magnetic sockets hold the fastener in driving position, even when working straight down. Time-wasting motions are eliminated when starting fasteners or working in hard-to-reach areas
