Frequently bought together:


Install our edge alignment pins on any square to create a large, overhanging edge which can be used to index the square on a different plane. Depending on the square, this allows you to create edges which are 90 degrees (perpendicular), 45 degrees, parallel, and even 60 and 30 degrees from the edge.


  • Use it with our Monster squares to create a speed square for layout.
  • Use it to hang the square off the edge of a table for working vertical or perpendicular to table surface
  • Use it to elevate the squares off the ground or table for extra clearance when you’re fitting and welding entire frames
  • Tip! If trying to create a parallel edge with the mega square for marking, use our shims to get that perfect distance!


Pins come in two lengths:

  • 1" length x 5/8" diamater is smooth along the faces and features a 3/16 hex drive at the top
  • 2" length x 5/8" diamater features a recessed knurl for grip near the top for better grip and a 3/16 hex drive at the top. The recessed knurl prevents scraping of the knurled edges against sensitive work surfaces.

    These pins are a clever invention to ad to the squares to help keep pieces in alignment so you can tack or weld them in place !!!!

    Great addition to an already great product. Weight and function are what I would expect from Fireball Tool.

    Edge alignment pins, what can be said except they are just like every other fireball tool. Excellent craftsmanship and end user friendly. No welder should go without fireball tools in their corner. First rate all the way!!!!!!
