Wera 8790 HMB Deep 3/8" Drive Hexagon Socket Metric
The Wera 8790 HMB Deep 3/8" Drive Hexagon Socket in 21mm handles larger fasteners with the added advantage of a 64mm deep profile, enabling access to bolts set below surface level or paired with long threaded shanks that would prevent a standard socket from engaging correctly.
Conforming to ISO 2725 part 3, it is rated for manual ratchet and machine operation (non-impact), offering flexibility for a wide variety of tasks. The hexagonal profile ensures clean, precise engagement and efficient power transmission, while the knurled lower end delivers a firm grip for hand use — particularly useful in tight or difficult-to-reach positions.
Wera's 'Take it easy' colour system makes locating the 21mm quick and straightforward.
Features and Benefits:
• 64mm deep length for low-lying and recessed fastener access
• Hexagonal profile for precise, high-torque bolting
• 'Take it easy' colour coding for quick size identification
• Knurled lower end for secure, slip-proof manual grip
• Ball intercept ring for drive retention
• Matt chrome-plated chrome-vanadium steel
