1.5THWB Weld-on SMR Adapters

1.5THWB Weld-on SMR Adapters

Weld-on adapters for permanent fixture use

The 1.5THWB Series magnetic adapters are meant to be welded permanently in place on any customer fixture. The button base (available in a variety of diameters) gives you an excellent locating reference. A substantial chamfer around the bottom edge makes for a nicer weld. This item is not hardened like most of our other adapters, and is available in a variety of materials. Install it on your fixture in a matching size hole, add a few weld tacks around the perimeter, and you have a permanent SMR reference. It’s sort of a non-drifting drift nest.

The adapter holds the centerpoint of a 1.5" diameter SMR 1" above the surface of the part, although this dimension is not critically controlled because this weld-on adapter is simply meant to establish a permanent reference point. The SMR locates on a 3-point conical land.

The magnets are provided (one per adapter) but not installed. This is so that you can heat treat the entire fixture after all adapters are welded on (if desired) without affecting the magnetism of the magnets. When ready, the magnets may be installed in the magnet well. We recommend securing the magnets using an adhesive for extra security. Of course, this is mandatory for 1.5THWB products constructed from non-magnetic materials. (Hint: don’t do this until you are finished with your processing – sometimes they’re very hard to get back out!) See our related 1.5THW, which is the same thing without the button locator.

Please note that other materials and button diameters are available upon request.
