Exact OEM Replacement for GM Trim Screws

These 7 mm trim screws are fresh factory OEM parts designed as direct replacements for GM Part 11503396. Sold as a set of 25, they reproduce the fasteners used on GM assembly lines, offering an authentic fit for a wide range of GM models and applications.

Key specs include thread size M4.2-1.41 (equivalent to #8), length 3/4 inch (19 mm), and a 7 mm indented hex head paired with a 12 mm outside diameter washer. The black phosphate finish delivers a durable, low glare look that blends with most trims and panels.

These screws are designed to align with the way GM panels and shields are secured, providing a reliable, factory-like seating. The indented hex head engages tools securely, helping you install with confidence even in tighter spaces.

What these screws are best for

  • Interior panels and trim pieces that require a clean, factory-style appearance
  • Exterior splash shields and exterior panels that benefit from a secure, flush seating
  • Engine bay components that call for authentic OEM fasteners for consistent performance

Why choose these OEM-grade screws

  • Direct replacement for GM Part 11503396 with verified measurement and thread
  • Sold as a set of 25 for convenient stocking and multiple fastening tasks
  • Authentic design widely used on GM applications to maintain consistent assembly standards

Installation and care

Align the panel, insert the screw with the correct driver, and seat the washer evenly. Apply the appropriate torque to avoid stripping and ensure a secure hold. Keep the screws in the original packaging to prevent loss and mix-ups.
