GM GENUINE PARTS Multi-Purpose Bolt 11589123 — OE Fit, Corrosion-Resistant Fastener

The GM Genuine Parts 11589123 Multi-Purpose Bolt is an original-equipment quality fastener engineered and validated by GM engineers for reliable fit and long-term service in Chevrolet, Buick, GMC, and Cadillac vehicles.

This bolt is manufactured to GM's production standards and undergoes the same design validation and testing used for parts installed during vehicle assembly. That means the 11589123 bolt matches the dimensions, material properties, and finish required for compatible GM models, helping ensure proper torqueing, alignment, and corrosion resistance compared with generic aftermarket hardware.

What makes this bolt different from generic replacements?

The 11589123 is produced or validated by General Motors to meet original-equipment specifications rather than generic tolerances. That control over design and materials reduces fitment surprises and improves durability where precise thread engagement, head size, or coating matters.

• Manufactured/tested to GM OE standards for dimensional accuracy and strength
• Engineered by GM to match assembly and service requirements for specific models
• Often uses corrosion-resistant finishes approved by GM engineers
• Backed by GM's parts identification and service documentation

How do I know if 11589123 is the right bolt for my repair?

Confirm the part number against your vehicle’s service manual, parts catalog, or GM dealer parts system. Fitment depends on model year, assembly location, and subassembly; using the exact part number avoids incorrect lengths, thread pitches, or head styles that can affect function.

• Check your vehicle’s VIN and GM parts catalog for compatibility
• Compare thread pitch, shank length, and head type with the removed fastener
• Consult a GM dealer or trusted repair manual when in doubt

How should this bolt be installed and maintained?

Install using the torque values and sequence specified by the vehicle’s service instructions to avoid overstressing or loosening. Use proper thread lubricant or threadlocker if the service procedure calls for it, and inspect the fastener visually during routine maintenance for corrosion or wear.

• Tighten to manufacturer-specified torque with a calibrated tool
• Replace rather than reuse if threads, head, or shank show damage
• Use recommended coatings or lubricants per service documentation

Will choosing a GM Genuine bolt affect warranty or service records?

Using GM Genuine Parts helps maintain factory-equivalent repair quality and aligns with official service recommendations. While specific warranty outcomes depend on terms and the nature of the repair, using validated OE parts reduces the risk of fitment-related failures that could complicate service claims.

• GM validation supports correct fit and function for covered repairs
• Part numbers are traceable through GM parts documentation and dealers
• Using OE parts simplifies ordering the exact replacement in future maintenance
