Designed for mechanics and DIYers who demand OE quality, this replacement bolt restores secure terminal clamping force without stripping or corrosion concerns. Whether you’re performing routine battery maintenance or replacing damaged hardware, our 19115561 terminal bolt delivers the durability and precision your electrical system depends on.
- OE-quality construction meeting GM factory specifications
- Corrosion-resistant finish for extended service life
- Precise thread pitch and head dimensions for proper torque application
- Direct replacement for worn or damaged battery terminal bolts
- Compatible with top-post battery terminal clamps
Materials & Construction
We manufacture the acdelco battery terminal bolt 19115561 from heat-treated steel alloy chosen for its superior tensile strength and resistance to vibration loosening. The bolt features a protective finish that guards against sulfuric acid fumes and moisture intrusion common in engine compartment environments.
The head design incorporates a hex profile sized for standard 10mm wrenches or sockets, allowing you to apply the manufacturer-specified torque without cam-out or fastener damage. Thread engagement extends deep enough to maintain clamping force through thousands of thermal cycles, while the included washer distributes pressure evenly across the terminal clamp surface.
Installation & Torque Specifications
Proper Torque Application
Installing the ACDelco battery terminal bolt 19115561 requires a calibrated torque wrench to achieve optimal clamping force. We recommend tightening to 10-15 Nm (89-133 lb-in) for most top-post applications, though always verify your specific vehicle’s service manual recommendations.
Before threading the new bolt, clean the terminal post and clamp surfaces with a wire brush to remove oxidation and sulfate buildup. Position the washer beneath the bolt head, then hand-tighten the assembly before applying final torque in a single smooth motion.
Compatibility & Applications
The acdelco battery terminal bolt 19115561 serves as a direct replacement in GM vehicles equipped with top-post batteries, including many Chevrolet, GMC, Buick, and Cadillac models. This part number cross-references to multiple year ranges and platforms where the original terminal bolt design remains unchanged.
We verify fitment through GM’s parts catalog database, so you can trust the 19115561 matches your vehicle’s electrical system requirements. The bolt works with both positive and negative terminal clamps, provided they use the standard GM fastener pattern.

Questions About the 19115561 Terminal Bolt
We recommend tightening the acdelco battery terminal bolt 19115561 to 10-15 Nm (89-133 lb-in) for most GM applications. Always consult your vehicle’s service manual for the exact specification, as some models may require different torque values.
Use a calibrated torque wrench rather than impact tools to prevent overtightening, which can crack the battery post or damage terminal threads. Apply torque in a single smooth motion after hand-tightening the bolt.
The ACDelco 19115561 is engineered specifically for GM vehicle applications. While many manufacturers use similar terminal bolt designs, thread pitch and head dimensions can vary.
Before ordering for non-GM applications, compare your existing bolt’s measurements to our specifications. The 19115561 features standard metric threading compatible with most domestic top-post terminal clamps, but import vehicles may require different fastener sizes.
Yes, each ACDelco 19115561 battery terminal bolt includes one flat washer. The washer distributes clamping force evenly across the terminal clamp surface and prevents the bolt head from deforming the clamp material during tightening.
Always install the washer between the bolt head and terminal clamp—never omit this component, as proper load distribution is critical for maintaining secure electrical connections over time.
The 19115561 features a corrosion-resistant finish designed for battery compartment environments. To maximize service life, clean terminal posts and clamps thoroughly before installation to remove existing sulfate buildup and oxidation.
After tightening the bolt to specification, apply a thin layer of dielectric grease or battery terminal protection spray around the connection. This creates a moisture barrier that prevents sulfuric acid vapors from attacking the bolt finish and terminal surfaces.
We recommend inspecting terminal bolts carefully during every battery service. If threads show wear, the head is rounded from improper tool use, or corrosion has penetrated the finish, replace the bolt with a new ACDelco 19115561.
Bolts that appear undamaged can be reused if cleaned properly with a wire brush. However, battery terminal bolts are inexpensive insurance against electrical problems—many technicians replace them automatically during battery changes to eliminate potential failure points.
ACDelco battery terminal bolts meet GM’s original equipment specifications for material composition, heat treatment, and corrosion resistance. Generic hardware store bolts may use softer steel alloys or inferior coatings that corrode rapidly when exposed to battery acid vapors.
The 19115561’s thread pitch and head dimensions are verified against GM engineering drawings, ensuring proper torque application and load distribution. This precision fit prevents the terminal connection failures, voltage drops, and intermittent electrical faults common with mismatched fasteners.
Battery terminal bolts secure the cable clamps to the positive and negative posts on top of your battery. Open the hood and locate the battery—you’ll see the bolts threading through the terminal clamps where battery cables connect to the battery posts.
Most GM vehicles position the battery in the engine compartment, though some trucks and SUVs mount batteries under the rear seat or in the cargo area. Refer to your owner’s manual for the exact battery location in your specific model.
