Socket 3/8" to 7/16" 12-point, Unior 616926
Unior 616926 is a 12-point socket adapter that converts a 3/8" drive to a 7/16" fastener interface. Made of hardened steel, it provides a precise fit for 12-point nuts and bolts and is intended for use with hand ratchets, torque wrenches and manual drive tools where a compact, reliable adapter is required. The compact form factor allows access to confined spaces while maintaining a secure connection between the drive and the fastener.
This 12-point socket adapter offers reliable torque transfer and a tight seating on 12-point profiles, reducing the chance of slipping or rounding fastener corners. Its hardened-steel construction ensures durability during repeated use in automotive, mechanical maintenance and general repair tasks. The adapter’s 3/8" to 7/16" conversion simplifies tool sets by allowing existing 3/8" drives to operate 7/16" fasteners without adding separate sockets.
Attach the adapter to the 3/8" drive of a ratchet or handle until it seats firmly. Fit the 7/16" 12-point fastener onto the adapter and apply torque using smooth, controlled motions to avoid impact loads. For torque-critical operations use a calibrated torque wrench and verify seating before applying full torque. After use, clean debris and lightly oil contact surfaces to prevent corrosion and ensure easy future attachment.
Use the adapter only within the torque range specified for the drive and the tool being used. Avoid using with impact tools unless the adapter is explicitly rated for impact service. Store in a dry toolbox to maintain condition and regularly inspect contact surfaces for rounding or wear.
