SUM781240 - Sumner Qwik Pins Flange Alignment Set 5/8-1.625 Inch

Sumner 781240 Qwik Pins: The Standard for Flange Fit-Up

Achieving perfect flange alignment is critical in pipe welding, and the Sumner 781240 Qwik Pin Set is the tool of choice for professionals seeking speed and precision. These flange pins, often referred to as "two-hole pins," are designed to align the bolt holes of a flange with the vertical or horizontal centerlines of the pipe. The 781240 model specifically caters to bolt holes ranging from 5/8" to 1-5/8", making them suitable for a broad spectrum of flange classes and pipe sizes. The standout feature of these pins is the "Qwik" release technology, which allows the operator to slide the fastening nut rapidly into position without threading it the entire length of the stud.

Constructed from heavy-duty steel, these pins are built to last. In the demanding world of pipe fabrication, tools must be able to survive drops, heat, and rough handling. Sumner has engineered these pins to resist deformation and wear, ensuring that they continue to provide accurate centering year after year. The conical shape of the pin heads ensures that they self-center in the flange holes, creating a perfectly level plane across the top of the flange. This allows the pipe fitter to place a standard torpedo level or spirit level across the pins to verify the flange's orientation before welding begins.

The operation is simple: insert the pins into the two upper holes of the flange. Press the quick-release button to slide the nut down, then release the button to engage the threads for a final tight fit. Once the flange is leveled and tacked, removing the pins is just as fast—press the button and slide the nut off. This efficiency makes the Sumner 781240 a favorite among field welders and shop fabricators alike. It removes the tedious aspect of manual alignment tools and replaces it with a fast, reliable mechanical solution.
