EZ Loader 1/2"-13 x 3" Hex Head Bolt — Structural Mounting Hardware
This OEM EZ Loader hex head bolt is designed for trailer applications where proper length, clamping force, and reliable fitment are required. At 3" long, this bolt is commonly used in bracket mounting and mid-depth hardware connections where shorter bolts are not sufficient.
While 1/2"-13 hardware is common, overall length determines proper fitment. This bolt is sized to match EZ Loader mounting configurations—not just general-purpose fastening.
| Part Number: | 290-001537 |
| Component Type: | Hex Head Bolt |
| Diameter / Thread: | 1/2"-13 UNC (Coarse Thread) |
| Length: | 3" |
| Grade: | Grade 5 |

| Important Note: | Always match bolt size, length, and grade to the application. Incorrect length can reduce clamping strength and affect structural fitment. |
Designed for Mid-Depth Trailer Mounting
This bolt is commonly used where bracket thickness and frame spacing require more reach than short bolts, but not full through-bolt length.
- Bracket-to-frame connections
- Bunk and roller support brackets
- Winch stand and post mounting
- Tie-down and accessory brackets
Built to maintain clamping force under real-world trailer conditions.
Grade 5 Strength
- Medium carbon steel construction
- Stronger than standard hardware bolts
- Designed for structural and mounting applications
Provides reliable strength without excessive brittleness.
Zinc-Plated Finish
- Sacrificial corrosion protection
- Helps protect base metal and surrounding components
- Consistent with OEM trailer hardware systems
Zinc is designed to wear first, helping protect the trailer over time.
Why This Part Matters
- Maintains proper clamping force
- Supports structural integrity
- Reduces loosening under vibration
Hardware is part of the trailer system—not interchangeable by appearance alone.
Real-World Insight
At EZLoaderParts411.com, mid-length bolts like this are commonly used where bracket depth and mounting geometry require additional reach. Using the correct length ensures proper thread engagement and long-term reliability.
