Bonbo 9‑Pin Axle Nut Socket for GM Silverado/Sierra 2500/3500 (2020+) — 1/2" Drive, Black Oxide

Bonbo 31510 is a hardened 9‑pin axle nut socket engineered to remove and install hub nuts on 2020‑and‑newer GM Silverado and Sierra 2500/3500 trucks with 11.5" or 12" dual rear wheel hubs.

This precision socket is made for professionals and home mechanics who work on GM heavy‑duty pickups. Built from hardened steel with a black oxide finish, the tool engages hub nut notches with a nine‑pin pattern and fits a standard 1/2" drive, giving reliable grip and corrosion resistance during high‑torque service.

How does this socket make axle hub work faster and safer?

The 9‑pin geometry lines up with the nut notches so you get a secure, slip‑free engagement each time. That reduces rounding of fasteners and speeds removal or installation, especially on full‑floating hubs commonly found on heavy‑duty GM trucks.

• Nine pins precisely match hub nut notch profiles
• Secure engagement lowers risk of slippage
• Fits 1/2" drive ratchets and torque tools for convenience
• Black oxide finish protects under harsh shop conditions

Will this socket fit my Silverado or Sierra hub nut?

The Bonbo 31510 targets 2020 and newer GM Silverado and Sierra 2500/3500 models with 11.5" or 12" dual rear wheel axle hubs. It also works on other vehicles whose axle nut outer diameter measures about 2.97".

• Designed for 2020+ GM 2500/3500 dual‑rear hubs
• Suitable for 11.5" and 12" dual wheel hub assemblies
• May fit other 2.97" O.D. axle nuts — measure before ordering
• Not a universal socket; confirm compatibility with dimensions

What tools do I need to use the 31510 socket correctly?

Attach the socket to any standard 1/2" drive ratchet, breaker bar or impact‑rated wrench and align the pins with the nut notches. Apply torque steadily; the hardened construction stands up to workshop use without deforming.

• Requires a 1/2" drive ratchet, breaker bar, or impact wrench (not included)
• Line up pins with nut notches before applying torque
• Use appropriate torque settings for your hub assembly
• Hand or powered drives both compatible — check OEM specs

How durable is the Bonbo 31510 under repeated shop use?

This socket is manufactured from hardened steel and finished in black oxide to resist rust and wear. The material and heat treatment provide toughness for repeated high‑torque operations typical in professional and DIY settings.

• Hardened steel core for strength and longevity
• Black oxide finish offers corrosion resistance
• Designed to resist pin deformation under load
• Built for repeated service on heavy‑duty axle nuts

Who is this for: The Bonbo 31510 is geared toward mechanics, fleet technicians, and experienced DIYers who service GM 2500/3500 trucks with dual rear wheels. If you maintain full‑floating hubs or perform routine axle service on 2020+ Silverado and Sierra models, this socket supplies the correct pin pattern, drive size, and durability needed to complete the job efficiently.
