Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why are accurate torque specifications important for body bolts?
Why are accurate torque specifications important for body bolts?
Accurate torque is crucial to prevent over-tightening, which can damage the body panels, crush mounting points, or strip threads, or under-tightening, which can result in loose panels, rattles, and potential safety hazards. Consistent torque ensures proper clamping force and prevents issues arising from uneven pressure distribution across the bolted connection. For example, if you over-tighten the bolts securing the front fenders, you could easily distort the metal or damage the paint.
Q2 What if I don't have a torque wrench?
What if I don't have a torque wrench?
While a torque wrench is the best tool for accurate tightening, you can temporarily use a standard wrench by 'feel' if you have experience. However, this carries a high risk of over/under-tightening, especially for inexperienced users. It’s highly recommended to borrow or purchase a torque wrench for this task. Always prioritize accuracy over convenience to prevent damage. If you can't obtain a torque wrench, it is best to wait until you can.
Q3 Can I reuse body bolts?
Can I reuse body bolts?
It's generally recommended to replace critical body bolts, especially self-locking types or those that are visibly damaged, rusted, or stretched. While many non-critical body bolts can be reused, inspect each one carefully for damage. If reusing, ensure the threads are clean and apply a small amount of anti-seize to the threads for easier future removal. This will help prevent issues such as seizure or galling.
Q4 Do I need to use threadlocker on body bolts?
Do I need to use threadlocker on body bolts?
Threadlocker isn't typically required for most body bolts unless the factory manual specifies. Some bolts, especially those in areas subject to vibration, might come with a pre-applied threadlocker or a locking flange. If the bolt did not have a threadlocker and it's in a non-critical area, you typically won't need to add it; but it may provide additional peace of mind. Refer to the service manual for specific recommendations for the location. For example, bolts holding the door hinge may benefit from a small amount of threadlocker.
Q5 What are common torque specs for Integra body bolts?
What are common torque specs for Integra body bolts?
While specific torque values vary depending on the bolt location and size, many smaller body bolts on the 1989-1993 Integra use a range of 8-12 ft-lbs. Larger bolts, such as those securing the bumpers or core support, may use torque ranges of 15-22 ft-lbs or more. ALWAYS consult the official service manual for your vehicle year and trim for exact torque values as deviation can cause damage. You can expect the general body structure, fender, door and hatch bolts to be on the low end, while the front bumper support, core support, and hood hardware will be at the higher end.

Technical Service Bulletins
Corrosion Issues Around Hatch Hinges
1992-05-15Early 1990s Integras may exhibit corrosion around the hatch hinge area due to water intrusion. Corrective action includes cleaning the affected area and applying anti-corrosion treatment along with proper torque of the bolts.
Resolution: Remove any corrosion, apply rust preventative treatment, and properly torque the hinge bolts, while ensuring proper sealing around the hinge area. Refer to service manual torque specifications.
Front Bumper Mounting Bolt Corrosion
1990-11-01Front bumper bolts may corrode over time leading to loosening or breaking upon removal. It's recommended to inspect the bolts, replace if necessary, and apply anti-seize when reinstalling with correct torque.
