Bonbo 9-Pin Axle Nut Socket 2.97" for 2020+ GM Silverado/Sierra 2500/3500 — 1/2" Drive, Hardened Steel

This specialized socket is built to remove and install the circular hub nuts used on full-floating dual rear wheel hubs found on certain GM trucks. Machined from hardened steel and finished in black oxide, the tool engages the nut with nine pins to reduce slippage, protect surrounding components, and work with common 1/2" drive tools. It’s a single-purpose, professional-grade item that speeds axle service while minimizing the chance of damage to the hub nut.

Which trucks and axle nuts will this socket actually fit?

The Bonbo 31510 is engineered to fit 2020 and newer Chevrolet Silverado and GMC Sierra 2500/3500 models equipped with 11.5" or 12" dual rear wheel axle hubs. The socket works where the axle nut has an outer diameter near 2.97" and matching 9-pin engagement notches.

• Compatible: 2020+ GM Silverado/Sierra 2500/3500 dual rear wheel hubs (11.5" and 12").
• Alternate fit: May fit other vehicles with a 2.97" O.D. axle nut and 9-pin pattern.
• Drive requirement: 1/2" drive ratchet, wrench, or breaker bar (not included).

How does the 9-pin design protect the hub and speed repairs?

The nine pins engage the nut’s notches to distribute torque evenly, reducing rounding or slippage compared with generic sockets or makeshift tools. That secure engagement allows faster loosening and tightening with less force, saving time during disassembly and reassembly of the hub.

• Even torque distribution reduces risk of damaging nut or hub components.
• Secure grip prevents slipping that can mar surrounding hardware.
• Efficient operation shortens service time for axle or bearing jobs.

What materials and finishes ensure durability under heavy use?

The tool is forged from high-hardness steel to withstand repeated high-torque applications, and its black oxide finish helps resist rust and wear. These features make it suitable for professional shop environments or home garages where tools see regular heavy use.

• Hardened steel construction for impact and torque resistance.
• Black oxide finish provides corrosion resistance and longevity.
• Precision-machined pins maintain engagement accuracy over time.

How do you use this socket safely and effectively?

Align the socket’s pins with the notches on the hub nut, attach it to a 1/2" drive tool, and apply controlled torque to loosen or tighten. Use the correct torque spec for your vehicle and confirm the fit before applying high force to avoid damage.

• Line up all nine pins with the hub nut notches before applying force.
• Use a quality 1/2" drive ratchet, torque wrench, or breaker bar as needed.
• Follow OEM torque specifications when reinstalling the hub nut.

Who is this for: The Bonbo 31510 9-pin axle nut socket is aimed at professional mechanics, fleet technicians, and experienced DIYers who service 2020-and-up GM 2500/3500 dual-rear-wheel trucks. If you regularly perform hub, bearing, or axle work on these models and need a reliable, purpose-built socket to reduce rework and protect components, this tool is a straightforward shop essential.
