About this item

  • Product-Specification: The Track Carriage Bolt and Nut - the perfect solution for secure and smooth garage door operation. These 1/4" x 5/8" Flathead Bolts with Knurled Neck and 1/4"-20 Threads are specifically designed for vertical and curve track applications.
  • Enhanced anchoring performance: The bolts' granular pattern increases friction within the material, preventing loosening under vibration or load and draw in flush with the track when tightened. This allows the roller to pass unobstructed, ensuring a seamless and efficient operation and ensures a reliable and secure connection. Highlights the unique feature of the bolts and its ability to resist loosening under challenging conditions. No more worries about your garage door getting stuck or jammed!
  • Improved-Design: Crafted with precision and durability in mind, these Track Bolts feature thin flat heads that hug close to the material they are holding. This is especially crucial for overhead door tracks, as it allows the rollers to pass by in close proximity without any interference.
  • High tensile strength: The products are made of high-strength alloy steel, ensuring a stable and secure fastening point. With excellent tensile strength, they can withstand greater force, providing stability and durability.
  • Easy to Install: To ensure a easy installation, each pack includes lock nuts that are specifically designed for a 7/16" socket. This provides added stability and peace of mind, knowing that your garage door hardware is securely fastened.

Before buying these I went through an ordeal with another seller that couldn't or wouldn't send the quantity they advertised ( twice ), I should have gone with these guys first and saved myself some grief.

My Werner 24' Extension Ladder (D-1324-2EQ) has adjustable Equalizer legs at the bottom for use on uneven ground. The hardware that attaches the Equalizer legs to the ladder uses bolts exactly like this. One of the existing bolts twisted off when I was removing it as part of a repair. And I had barely touched it. These bolts are a perfect fit for replacing the broken one. In fact, I think I'll replace all 8 of them while I'm at it, since if one of the existing bolts was compromised, they may all be at this point. And I like the locking teeth on these new nuts too.

They worked but I thought the threads were a little sloppier than usual

The bolt threads stripped when tightening them. I had other bolts to use so I didn't use anymore of these bolts that I purchased.
