D.169 Set of 3 couplers

• Allows use of square drivers smaller than socket drive sizes:
– 1/4″ square drive + D.169RJ –> 3/8″ socket (ø 1/4′ : 28,7 – R 1/4′ : 13 mm).
– 3/8″ square drive + D.169JS –> 1/2″ socket (ø 3/8′ : 37,8 – R 3,8′ : 16 mm).
– 1/2″ square drive –> 3/4″ socket (ø 1/4′ : 43,9 – R 1/8′ : 22).
• Compactness means that fewer tools are needed for in situ maintenance
operations.
• Magnetic retainer and locking system (JS and SK).
• Knurl allows hand tightening where access is difficult.
