H21 3/4' Drive Impact Bit Socket (100mml)

Features

• H21 hex — suits internal hex fasteners requiring 21 mm drive.
• 3/4″ square drive — fits heavy-duty ratchets and impact wrenches.
• 100 mm length — extra reach around guards and recessed fittings.
• Impact-rated construction for repeated high-torque use.

Benefits

• High leverage: 3/4″ drive pairs with powerful tools for stubborn fasteners.
• Better access: Longer body improves alignment in recessed locations.
• Reduced rounding: Correct hex geometry transfers torque cleanly.

Extra Information

• Use with impact-rated extensions/adapters where required.
• Keep mating fasteners clean; debris increases wear and slippage.
• Lightly oil after use to resist corrosion in workshop environments.
