Steelman 3-3/4-Inch 8-Point Locknut Socket | 3/4-Inch Drive for Truck Wheel Bearing Nuts

Meet the Steelman 60284-25 3-3/4-Inch 8-Point Locknut Socket—a purpose-built tool designed to simplify the task of removing and installing large wheel bearing locknuts and other substantial fasteners. Built to grip the flats along the fastener face, this 8-point design helps reduce wear on corners and minimize rounding. Constructed from high-strength carbon steel, the socket stands up to repeated use in demanding workshop environments. A durable black powder coat resists chips and fading, keeping the tool looking sharp even after hard use.

Key features at a glance

• 3/4-inch drive: a heavy-duty socket designed for straightforward installation and removal on large locknuts
• Durable steel: high-strength carbon steel for lasting performance
• Corrosion resistant: industrial-strength black powder coating that stays intact
• Laser etched markings: size callouts stay legible and won’t rub off
• 8-point design: grips the sides of fasteners rather than the corners to reduce wear

How it fits into your workflow

• Compatibility: works with any hand-operated 3/4-inch drive ratchet, extension, adapter, or torque wrench
• Control and feel: the laser-etched sizing and robust steel offer clear feedback during use
• Preservation: the 8-point gripping action helps prevent premature rounding or damage to the fastener

Real-world use cases

• Truck maintenance and fleet service: remove stubborn wheel bearing locknuts during routine service
• Industrial and agricultural equipment: tackles large fasteners on heavy machines

Usage notes: this tool is designed for manual operation. Do not use with power or impact wrenches, which can cause damage or improper engagement. For best results, apply steady, even torque with a properly rated 3/4-inch drive ratchet or torque wrench and double-check alignment with the 8-point faces.

Why choose Steelman: the combination of a precise 8-point design, laser-etched readouts, and a corrosion-resistant finish supports reliable, long-term performance. The tool feels solid in hand, with the weight and balance you expect from a high-grade carbon steel socket. While no tool can guarantee outcomes, customers often notice smoother engagement, reduced wear on fasteners, and clearer identification of the right size on the job.
