Petol Flange Alignment Pins, Pair, 7/8" x 3.5", Black, 4140 Heat Treated Steel, Tapered, Faster Flange Bolt Hole Alignment, Drift Pin Alternative

Traditional tools like drift pins, bullpins, and spud wrenches may get the job done, but not without compromise. They rely on brute force, often wedging themselves tight in the flange and requiring just as much effort to remove as to install. Every extra swing slows the crew down, introduces risk, and chips away at productivity during critical maintenance windows. Flange Alignment Pins by Petol Gearench are engineered to eliminate wasted motion and reduce flange alignment time. Simply insert one pin, rotate 180°, then insert and rotate the second pin to bring the flanges into alignment. Once the flanges are aligned, the pins withdraw effortlessly by hand, eliminating the need to hammer out a stuck drift pin or bullpin. Each alignment pin is precisely sized for its corresponding bolt hole and features a tapered shaft design that gradually pulls flanges into alignment as you rotate. This simple twist-in, twist-out motion makes the process faster, easier, and repeatable — ideal for pipefitters, plant maintenance crews, and industrial turnaround teams who need consistency under pressure. This listing is for a pair of standard-length flange alignment pins. Each Flange Alignment Pin is machined from heat-treated 4140 steel and finished with a black oxide coating for durability and corrosion resistance. If you work around flanged piping, you know bolt-up can be the most frustrating part of the job. Flange Alignment Pins make it easier. They reduce the time, strain, and improvisation that usually come with lining up flanges. Whether you're supporting a turnaround, working a planned outage, or doing critical maintenance in the field, these tools help keep crews moving. Trusted by pipefitters, millwrights, and maintenance teams in refineries, chemical plants, and power facilities, Flange Alignment Pins bring consistency and speed to every bolt-up.

• Corrects All Flange Misalignment: Rotating the pins will bring flanges into alignment faster and with less effort; remove easily by hand without hammering or prying
• Sized by Bolt Hole, Not Stud Size: These pins are sized for 7/8″ bolt holes, which match flanges with 3/4" studs; must be selected by bolt hole diameter, not stud size, for proper fit
• Used by Maintenance Crews and Pipefitters for Flange Bolt-Up: Trusted in refineries, plants, and construction sites to align flanges quickly, safely, and without hammering
• Built for Industrial Use: Made from 4140 heat-treated steel with a black oxide finish; built to withstand repeated use in harsh industrial environments
• Replaces Drift Pins, Bull Pins & Spud Wrenches: Align flanges safely without hammering; simply insert, rotate, and line up bolt holes for a perfect bolt-up every time
