    No-Strike Hex-Head Alignment Pins for Flange Bolt Holes

    Image of Product. Front orientation. Contains Annotated. Alignment Pins. No-Strike Hex-Head Alignment Pins for Flange Bolt Holes.
    The tapered shaft of these pins eliminates the need for hammering and prying when aligning flange bolt holes. To align bolt holes, fit the tapered end of the pin into the bolt holes and use a wrench on the hex head to rotate and align the holes. If your bolt hole is in between the sizes listed, choose the smaller size pin.

    Pipe Flange Aligner Pins

    Image of Product. Front orientation. Pipe Flange Aligners. Pipe Flange Aligner Pins.
    Insert a pair of these nut-and-bolt pins into adjacent flange holes and tighten to align flanges before connecting two pipes. One pin in each pair has a level for vertical alignment. Use a separate level to align the flange horizontally. Also known as two-hole pins.
    4 1/2" Lg. Extension—Pins with a 4 ½” length extension let you increase the length of your pins to align thicker flanges.
    Two Couplings—Use the included couplings to connect the extension to your pins.

    Alignment Pins with Tether Hole

    Often called bull pins, these pins are designed to resist mushrooming caused by repeated pounding. The large striking surface allows you to drive the pins quickly and efficiently. Use alignment pins to align structural components such as I-beams and angle irons for bolting, riveting, and welding.
    Alignment Pins with Tether Hole—For added safety, choose pins with a tether hole while working from heights.

    Each step on these aligner pins matches common bolt holes on pipe flanges, so they're more precise than conical aligner pins and don’t require nuts. Press the pair of pins into mated flanges to make sure the flanges are aligned. Once two sets of holes are aligned, you'll know the rest of the holes are as well. Made of durable chrome-plated steel, they'll hold their shape over time and resist rust.

    Ensure an even seal around your flange—these tools align and level flanges in a single step. The strong magnets make sure your bolt holes are perfectly inline horizontally and that your flange isn’t tilted. If your flange is made of stainless steel or another nonmagnetic material, secure these aligners using the included threaded cones.

    Swiftly and accurately align pipe flange bolt holes without the hassle of threads. These pins have strong magnets that snap together. Insert them into adjacent bolt holes to help make sure flanges are parallel before connecting pipes. Also known as two-hole pins.
    For 2 3/4" Flange Thickness—Pins for 2 3/4" thick flanges can be used with pipe flange aligner extensions (sold separately) to lengthen their reach for flanges up to 3 1/2″ thick.
