This OE Match door hinge bolt is manufactured to OE-equivalent standards using high-strength steel and corrosion-resistant surface treatment. It is engineered for proper engagement with the hinge and pillar threads, helping maintain correct door alignment and smooth hinge motion. Precise door fitment is essential for proper sealing, wind noise reduction, and panel gaps - all of which affect both appearance and vehicle comfort.

This bolt installs directly with no modification required and is suitable for individual replacement or during hinge service/adjustments.

A worn or corroded hinge bolt can lead to door sag, uneven panel gaps, increased wind noise, and difficulty closing the door correctly. A fresh OE Match door hinge bolt provides the necessary clamping force and fit precision to maintain door geometry, improve cabin sealing, and retain correct factory-style operation and feel.

When to replace:
• Noticeable door sag or misalignment
• Excessive play at the hinge
• Bolt corrosion or thread wear
• During door hinge servicing or hinge pin replacement
• Restoration or panel alignment work
