STEELMAN | JS-79390 | 1in DR. 21MM Budd Impact Socket

1in DR. 21MM 4-Point Standard Budd Impact Socket is a must-have for fleet mechanics and truck service techs working with dual-wheel hubs or Budd-style wheels. It’s built to safely and efficiently remove the inner cap nuts without rounding or slipping especially when time, torque, and tight spacing are working against you. If you’ve dealt with corroded or seized Budd wheels, this socket makes a difference you’ll feel on the first use.
What Makes a Good Budd Impact Socket?
The best Budd sockets deliver precise fitment and can stand up to repeated impacts under load. This STEELMAN model is machined to grip snugly on 4-point inner nuts, ensuring you don’t strip the corners or waste time readjusting your tool. Unlike universal 6-point sockets that risk slipping, this one is purpose-built for the job, which means fewer mistakes and faster wheel service.
- Square 4-point design made for inner cap nuts on Budd-style wheels
- Reduces rounding and tool slippage even on worn hardware
Budd Socket Performance on the Job
In actual fleet bays and roadside callouts, this impact socket shines by saving time and effort. It locks onto cap nuts firmly and releases clean, even under high-torque impact guns. The black phosphate coating adds protection from rust and road grime, and its laser-etched size markings stay readable even after repeated cleanings and heavy use.
- Fits securely with 1-inch drive impact wrenches
- Easy to identify in your toolbox with permanent size marks
