Aluminum Threaded Inserts for Thin-walled Objects

Using TP's threaded spouts, there are a lot of things that you might want to screw onto your penis. For instance, you might want to snuggly attach a hollow sphere to act as a penis extender and/or to keep your penis from slipping out of a vagina or anus after you’ve cum and it starts to get limp. Or you might want to attach a large ball, or perhaps a large soda bottle or milk jug, to act as a float while swimming, or to slowly fill with your own urine and act as a growing weight while you're in a stockade. Tether Products can’t begin to imagine all the wild things that users might dream up.

Hollow balls or spheres of all sizes, such as you might find in toy or sporting goods departments, and other interesting objects or containers of all shapes (perhaps to use in making a chastity device or other restraint) are easy to come by. The problem is that often they will be made of soft plastics or rubbers, or will have walls that are too thin or weak to be able to use a drill & tap set to simply cut in a threaded hole. That’s where these aluminum threaded inserts can come into play and easily make attachment to a threaded spout possible.

With these inserts and the installation tool set that TP sells separately, you can put a durable and corrosion-resistant threaded hole into almost any object, such as a hollow ball, a jar lid or bottle cap, or into virtually any container, provided it has a wall thickness that’s within the working range of 0.7mm to 4.2mm (0.03 to 0.16 inches) and provided you can put a reasonably accurate hole into it. If the wall is not thick enough, you may be able to compensate by putting a washer on the back side, if accessible. The procedure is as follows:

1. Make the hole with the drill bit that comes with the installation tool, or by whatever other means necessary.
2. Press in the threaded insert (it should fit snug) and press on a similarly snug washer on the backside (if accessible) to compensate if the wall is not already thick enough.
3. Screw on the pull-up bolt of the installation tool and then tighten the take-up nut while holding both the head of the bolt and the mandrel stationary, until the splined portion of the aluminum insert collapses and expands outward on the backside and squeezes tight to the inside wall of the object like a second flange.

 

The procedure can be done blind, from the front side only, and in most cases the flange of the insert will form a watertight seal. The process is much like putting a common wall anchor (like you find in the home improvement section of most stores) into drywall to hold a heavy picture or bookshelf bracket.

These aluminum threaded inserts are sold in sets of 5 for the convenience of TP's customers. Elsewhere you can usually only buy them in bulk, if you can find them at all. The installation tool set, consisting of a 10mm drill bit, hardened steel pull-up bolt with handle and take-up nut, thrust bearing, and mandrel (also with handle), is likewise of TP's own design and generally much cheaper than even the most inexpensive installation tools sold by others. You will need your own open-ended wrench to turn the take-up nut.

If you are a handy kind of guy, it is not even necessary to buy the installation tool set. You can make up your own compression tool just by using an ordinary M6x1.0 bolt along with a nut and a short stack of flat washers, but it may not work as smoothly and you may wish you had three hands. The handles on the mandrel and the pull-up bolt, and the thrust bearing that come with TP's installation tool set, are designed to eliminate torque on the insert & object and simultaneously make it easy to turn the take-up nut to compress the insert and squeeze it down. With a homemade tool, keeping the bolt, the insert and the object from turning along with the nut, or judging when the insert has been squeezed down tight enough, may become problematic. If you make your own, TP suggests you use two locking pliers to hold the bolt and the stack of washers stationary.

Note: In most cases, the threaded spouts that TP sells should be long enough, but if you have put an aluminum threaded insert into an unusually thick-walled object, you may need an extra long spout before you can screw it onto your dick, because the threads inside these inserts always start somewhat back of the inside wall of the object. Normal spouts may not reach far enough. Let TP know if that becomes the case. Longer threaded spouts may be offered, depending on demand.

Also, if you are wondering why these inserts are only offered in aluminum and not stainless steel, it is because stainless steel threaded inserts (besides being more expensive and almost impossible to get unless special ordered by the thousands) are much harder to compress and require more sophisticated heavy-duty tools.
