Strong Hand MFT10 MagTab: Tack-Welding Buying Checklist

Buy the Strong Hand Tools MagTab MFT10 only if your problem is holding a small steel tab or bracket for a temporary tack. It is an adjustable magnetic third hand, not a structural fixture, a lifting magnet, or a replacement for a rigid welding clamp. Before ordering, confirm that the workpiece is magnetically responsive, that the shape suits its V-pad, and that your process permits removing the magnet before the final weld.

This guide concerns the original MagTab 1.0, manufacturer part MFT10, matched to the single-item Amazon listing identified as ASIN B0087GAEDM. It does not describe the newer MagTab 2.0, the Mini MagTab, a magnetic ground clamp, or a multi-piece V-pad assortment. Names such as “adjustable magnetic holder” are not enough to distinguish these packages.

What the MFT10 does — and what it does not

The original MagTab combines a small adjustable bracket with a magnetic V-shaped base. According to Strong Hand Tools’ MFT10 specifications, it can temporarily position tabs and small metal pieces either parallel or perpendicular to their supporting steel. The bracket can be detached so the V-pad can be used separately for light workholding. This is a positioning aid: you still have to check the drawing, contact surfaces, and final restraint.

The manufacturer gives a maximum pull force of 18 lb and approximate dimensions of 4 × 3 × 1.3 inches. Its published magnetic-force reference is a 0.08-inch flat steel surface. That laboratory-style condition is not a promise of the same grip across mill scale, paint, oily surfaces, curved tube, a short tab, gaps, or stainless grades that are weakly magnetic. A stated pull force is not a welding load rating.

Start with the base metal and contact surfaces

A magnet requires a compatible ferromagnetic contact surface; it will not grip aluminum or many austenitic stainless materials in the way it grips carbon steel. A round tube can also present less contact area than a flat plate, despite the V-pad’s intended shape accommodation. Check the substrate, coating, curve and access before choosing this tool. If the joint must remain positively restrained, use a suitable mechanical clamp or purpose-built fixture instead.

For thin stock, holding force is affected by material thickness, flatness, air gaps and cleanliness. Do not assume the quoted maximum applies at a weld joint with a curled edge. The practical question is not whether the magnet sticks somewhere on the bench, but whether the tab remains located when you fit up, inspect and tack the actual part.

Compare the size of the tab with the adjustable bracket

A small bracket may need to sit square to a gusset, while a tab on round tube needs a different contact geometry. Before placing an order, lay out the approximate tab length, width, stand-off, access for the torch and direction in which the part could slip. The adjustable bracket helps with orientation, but cannot make an oversized piece safe or accurately located by itself.

Ask whether the magnet and bracket leave enough room to inspect the root, reach the tack area, and get the unit back out without prying against a newly joined part. A “third hand” is most useful when it reduces fumbling while you establish position; it is not a substitute for correct joint preparation or a second safety restraint on a heavy component.

Tack only: treat heat exposure as a hard limit

Strong Hand Tools specifies this MagTab for tack welding only and instructs removal before completing the weld. The manufacturer also warns against exposing it to temperatures above 175°F (80°C). Welding heat can demagnetize the unit or make it hard to handle. Follow the manufacturer’s limitations even when a nearby weld seems short or the contact surface initially feels cool.

Remove the holder before final welding once the work is adequately secured by the approved fixture or other suitable means. Do not position a hand on hot metal to recover it, do not use it as a lifting device, and do not use it as a substitute for engineering-approved temporary supports on a load-bearing assembly. The WPS, drawing, fixture design and safety controls govern the actual welding operation.

Confirm the exact package, not a catalog photo

• Manufacturer and version: Strong Hand Tools original MagTab 1.0, MFT10, not MET11 MagTab 2.0 or MFT05 Mini.
• Amazon identification: B0087GAEDM. Compare the seller’s full title, manufacturer part number and product photos before checkout.
• Selling unit: the matched listing describes one MagTab; check the current offer’s quantity and included components, especially when marketplace titles mention “kit.”
• Footprint and contact: check 4 × 3 × 1.3 in approximate unit size against your available space, the V-pad contact angle and working reach.
• Application: temporary tab positioning for tack welding on magnetically responsive steel; not continuous weld fixturing.
• Limits: verify heat exposure, accessibility, whether the piece can slip and whether the magnet can be removed safely.

Some listings describe a “six-piece” item because they count assembled components. That is not evidence that the offer contains six separately usable MagTabs. The source item is the MFT10 assembly; if the current seller’s package language conflicts with that identification, ask the seller to confirm the number of complete holders, rather than buying based on a fragment of marketplace metadata.

What about newer MagTabs and ordinary clamps?

Strong Hand’s current MagTabs family page distinguishes the original MFT10 from larger or newer configurations with different V-pads and holding-force figures. Those are different models, not interchangeable parts of the same Amazon ASIN. If you need greater reach, positive restraint, a nonmagnetic work surface or more repeatable fixture location, the right answer may be a mechanical clamp or table fixture rather than simply a bigger magnet.

For general clamp sizing, compare the actual opening and throat reach in WSP’s Strong Hand UF65 clamp checklist. For thin tabs or finished contact faces, the IRWIN 11SP swivel-pad clamp guide shows another geometry to evaluate. Neither is automatically a direct substitute for the MagTab: compare intended surface, position, clearance and restraint requirements.

A five-minute buying decision

• Sketch the part and mark the exact temporary hold point. Will a V-pad and bracket fit there without blocking the tack?
• Check that the base material will hold a magnet and that the contact area is broad, clean and flat enough for a reliable temporary grip.
• Decide whether a tool that must be removed before finish welding meets the job sequence. If not, choose a suitable rated mechanical fixture.
• Verify model MFT10 and ASIN B0087GAEDM, not a similar MagTab 2.0 or an accessory-only offer.
• Inspect the current seller’s delivered unit and return terms. Do not infer availability, current price or included extras from a saved blog image.

A good reason to buy MFT10 is straightforward: small, repetitive steel-tab fit-up where a temporary magnetic holder will free a hand and can be removed before the weld is finished. A poor reason is trying to hold heavy steel, position nonmagnetic metal or avoid building a real fixture. The exact product and published limits matter more than a generic “welding magnet” label.
