The Right Tools For The Job.

If the scent of lubricating oil and the sound of sockets clinking get your gears going, these TPR hex nuts will be perfect for the cock in your life. The tensile strength of the firm, body-safe TPR effectively improves erections, and these hex nuts can grace your cock in as many ways as your mechanical mind can theorize.
Nuts and bolts theme, body-safe pair has an effective tensile strength for improving erections.
TPR is a bit sticky, always requires lube lest it form tags. Can't be sterilized.
Rating by reviewer:
extremely useful review


Cock rings can be hot. For the men who wear them, the sensation can be appealing, orgasm can be intensified, and the cock encircled is a sight that'll make you proud. For a partner, the sight of a cock in a ring can be arousing, and the cock itself will be a bit bigger than usual. Orgasm can even be delayed so the whole experience will be enjoyed at length by both partners.

Topco's Hardware Coupling Hex Nuts are designed as constriction rings. Because blood flows into the penis through arteries in the center of the shaft, and drains through veins near the surface, a well-fitted cock ring can keep a cock engorged to a greater girth than wearer's standard erection.

The Coupling Hex Nuts can enhance your play in many ways---you can wear one ring or both, around balls, shaft, or both. And, saving the best feature for last, these steel-inspired rings will turn the engines of anyone with a hardware fetish. If you love to see your partner bent over the toolbox, lube up and slip these on before you put your wrenches in the drawers. If you're proud of your man's mechanical aptitude, and can't wait to jump his bones as he's bent over the workbench or helping you replace your sway bar links, slip this set into the toolbox.

Material / Texture

Topco's Hardware Coupling Hex Nuts packaging states that these cock rings are constructed from TPR, a phthalates-free and body-safe compound which is odor free, but not sterilizable. (Cock rings should only be used by fluid-bonded partners regardless, because they can easily stretch and tear condoms.)

The small ring is stretchy, and the larger ring is firm but malleable. They are made of the same blend of TPR, so the differences in response are a result of the different thicknesses. Both stretch sufficiently that, no matter what size you're fitting, these hex nuts will grace your nuts with ease.

The stretch provided by TPR is sufficient for fitting, but it's still firm enough to perform the cock ring's primary task of constricting blood flow a just the right amount. Unlike jelly rings, which exist mostly as a housing for a clit vibe, these Hardware Hex Nuts are serving a purpose while they're looking good.

With some manipulation (including unlubed manhandling for the sizing pictures), the smooth inside surface of the larger nut developed a small flap. This wasn't a problem when they were used with lubricant, so I'd suggest always lubing up (Topco suggests water-based lubricants only, no matter how tempting 5W30 might be) to extend the longevity of your nuts. It'll make insertion on your non-TPR nuts much easier, as well.
    • No odor

Shape / Design / Size / Fit

When you're working, you always want the right tool in the right size. Topco helps out by offering two hex rings for your enjoyment. The smaller ring, for use on the shaft only, matches the manufacturer's description of 1.75"H x 1.75" W x 0.50" D, an has an unstretched inside diameter of .75". The larger ring, designed to be worn either around balls and shaft or shaft alone, measures 2.5" H x 2.5" W x .70" D with an unstretched inside diameter of 1.75".

To test the rings' range, I tried them out on my two favorite realistic-style dildos, which happen to have the pretty disparate diameters of 1" and 1.875". The larger hex nut fits over balls easily and comfortably as well, both human and Lone Star.

    • Beginner
    • Can fit over both shaft and testicles
    • Will fit most men

Functions / Performance / Controls

Just like a real hex nut, these TPR nuts are simple in their form, straightforward in their function. They look hot, stiffen up a cock, and if your sex sessions usually last less than 30 minutes, they can prolong your performance.

Cock rings should not be worn for longer than 30 minutes, with an hour's rest between uses, to prevent bruising or other damage. This can actually add a bit of headache to an otherwise wonderful experience---unless you set an alarm, it can be distracting to have to wonder "how many minutes can we keep screwing?"

The sexiest designs are simple and functional.
    • Comfortable during use
    • Easy to use

Care and Maintenance

Hardware Hex Nuts can be put on simply by stretching them over your shaft, balls, or cock and balls (or the larger ring in one spot and the smaller on another). The themed packaging comes with a pamphlet containing detailed installation information and more for the eager new user, and while we followed the pamphlet, it turns out that you can just use your mechanical intuition to achieve the same results.

Unlike steel hex nuts, you will want to wash these fasteners with water and antibacterial soap before and after each use. (They're not going to rust, after all.) Because they can't be sterilized, again, don't switch among partners, and don't use cock rings unless you're in a condom-free relationship because the rings can cause tears.

The packaging comes in two parts, and I've been storing mine in the inner portion of the clamshell to keep lint off, but a plastic bag would work well too.
    • Easy to clean
    • Easy to store

Personal comments

Hardware Coupling Hex Nuts are hot as hot can be, for me. I really love turning wrenches with a mechanically apt partner, and the sight of these rings calls to mind the smell of lubricating oil, the soft clink of sockets, and the fire behind his eyes as we try to piece together the source of the problem we're solving. And they serve a purpose of their own while they're looking good---the firm TPR is quite effective at adding a bit of girth above-and-beyond the standard erection of the penis in your life. The material can be a bit fragile if you don't use lube, which is a shame, because I'd love for these to last forever, and it's a hassle to remember to have lube on hand. They're not quite as constricting as some other hexagonal cock rings, but, so far as I'm concerned, these nuts are the right tool for the job.
