Magnetic Alignment Pin

Product Overview MAP200


The Strong Hand Tools Magnetic Alignment Pin (MAP200) is a compact, 1.58 lb (0.72 kg) pipe-fitting tool engineered from CNC-machined, anodized aluminum to streamline the leveling and alignment of ferrous pipe flanges. Designed for efficient operation even while wearing heavy welding gloves, it utilizes spring-loaded, self-aligning pin heads that drop directly into adjacent bolt holes while integrated, ultra-strong magnets instantly lock the unit securely to the steel surface. Featuring a built-in bubble vial for fast horizontal calibration, the adjustable design accommodates pin diameters from 0.5 inches to 2 inches (12.7 mm to 50.8 mm) and center-to-center hole spacings from 3.14 inches to 6.97 inches (79.8 mm to 177.0 mm). This makes it highly versatile across standard flanges ranging from 0.5 inches up to 20 inches (12.7 mm to 508.0 mm), and it comes complete with a rugged, protective foam storage case to safeguard its precision components between tasks.

Adjustable Pin Span

Slides smoothly to accommodate a center-to-center distance from a minimum of 3.14" (79.8 mm) up to a maximum of 6.97" (177.0 mm).

Magnetic Pull Force

A strong 4.4 lb (2.0 kg) magnetic hold that locks the tool tight against the steel flange face so it won't slip or sag.

Body Material

Premium CNC-machined, anodized aluminum construction built to survive rough field drops while maintaining exact geometric tolerances.

Storage

Ships in a custom-fit protective foam case to shield the precision vial and machined surfaces from being scratched up in a heavy job box.

No-Fumble, Threadless Setup

Eliminates the frustration of spinning dirty, slag-covered nuts or dealing with crossed threads.

One-Handed Operation

Designed to be used completely while wearing heavy welding gloves. You simply snap it in and go to work.

Simultaneous Leveling

Features an integrated horizontal bubble vial right in the center frame, allowing you to align the holes and check your level in one movement without grabbing a separate torpedo level.

Spring-Loaded Self-Centering

The tapered pin heads instantly seat themselves firmly against the edges of the bolt holes for perfect concentric accuracy.

Why a Fabricator Needs It in Their Workshop

Traditional alignment pins turn a simple fit-up into a multi-step balancing act: you insert the pins, struggle to tighten them down with slick gloves, grab a separate level, and constantly tap the flange into place. If you drop a loose nut down a pipe or into the dirt, your momentum stops entirely.

The MAP200 turns this into a 5-second task. Because it uses internal springs and powerful rare-earth magnets, it clamps itself flush against the ferrous flange face automatically. It dramatically reduces setup time on repeat weldments, freeing up your hands to position the pipe, check your square, and lay down your tack welds without fighting your tools.
