Screw-On Plugs vs. Labret Studs: Picking Body Jewellery

Two fastening systems, two different jobs

The first decision is not style — it is where the jewellery goes and how it stays there. A screw-on plug uses a threaded backing to hold a solid piece in a stretched or standard-gauge hole. A threadless labret uses a flat back and a push-fit top, which is why it is usually chosen for lip, ear, and similar piercings where a flat disc sits behind the tissue.

That difference in fastening changes what you need to measure. Plugs are sold by gauge and often priced per piece, so a pair means ordering two. Labrets are sold by gauge plus bar length, and the top is a separate decorative element. Mixing those two sizing systems is the most common buying mistake.

How the three catalog options differ

• Screw-on plug — 316L surgical steel, black PVD, 2Ga: A solid plug with a screw-on backing and a multi-colour shell centre. Gauge is the only sizing figure supplied in the catalog record, so bar length and wearable area are not confirmed there.
• Threadless labret — implant-grade titanium, black PVD, 13mm bat top: Comes in three gauges and two lengths according to the catalog, with a flat back and a CZ gem bat top. The staff pre-bends the gem to fit the bar you choose, which is part of how threadless tops stay secure.
• Internally threaded nipple jewellery — implant-grade titanium, rose gold PVD, 14ga, 14mm: A third fastening type: one side screws off, and the catalog lists both thickness (14ga / 1.6mm) and length (9/16" / 14mm). It is a useful reminder that not every body piercing uses a plug or a labret.

What the plug record actually confirms

• Plug: 316L Surgical Steel Black PVD Multi-Colour Shell Center Screw On Plugs 2Ga: Material: 316L surgical steel; plating: black PVD; screw-on backing; 2Ga. 316L surgical steel is the material named in the listing, and PVD is a coating rather than the base metal. If you are comparing 316L surgical steel plugs, this record gives you the gauge and fastening but not a length or wearable-area figure.

  

• Plug: 316L Surgical Steel Black PVD Multi-Colour Shell Center Screw On Plugs 2Ga: Priced per piece — enter 2 for the pair. A plug purchase is not automatically a pair. Budget and order quantity have to be set deliberately, especially if you are buying for two ears.

Why the labret record asks more of you

The titanium labret stud is the more configurable option, and that cuts both ways. The catalog states three gauges and two lengths, plus a 13mm bat top and a flat back. It does not state which gauge-and-length combinations are stocked, so you cannot assume every pairing exists. Confirm the exact combination before ordering.

The material is listed as Ti-6AL4V-ELi ASTM F-136 implant-grade titanium, which is a specific alloy standard rather than a generic 'titanium' label. That is the detail worth checking when you compare a titanium labret stud against a steel alternative.

Labret and nipple jewellery: the sizing that is spelled out

• Labret: Titanium Black Bat Red CZ: Threadless implant-grade titanium labret with a flat back; 13mm CZ gem bat top; three gauges and two lengths listed; staff pre-bend the gem to fit the chosen bar. Bar length and gauge both matter here, unlike the plug listing. The pre-bend is part of the threadless fit, so the top and bar need to be matched rather than bought separately at random.

  

• Nipple: Titanium Purple Opal-Rose Gold: 14ga (1.6mm) thickness, 9/16" (14mm) length, 5mm purple opal gem, internally threaded with one side screwing off. This is the clearest sizing example in the catalog: thickness and length are both given in two units. Use it as a model for what to look for on any body jewellery listing before you buy.

A buying sequence that avoids returns

1. 1. Identify the piercing and the fastening type it needs: A stretched hole and a lip piercing do not take the same hardware. Decide between a screw-on plug, a threadless flat-back labret, or an internally threaded piece before you look at finishes.
2. 2. Write down the gauge you already wear: The plug is listed at 2Ga; the labret spans three gauges; the nipple jewellery is 14ga. Gauge is the one number every record gives you, so start there.
3. 3. Check whether length is stated: The nipple jewellery gives 9/16" (14mm). The plug record does not give a length, and the labret gives two lengths without saying which gauges they pair with. If length is missing, treat it as an open question, not a default.
4. 4. Count pieces, not pairs: Both the plug and the labret are priced per piece with a note to enter 2 for the pair. Order the number you actually need.
5. 5. Confirm the material and coating separately: 316L surgical steel and implant-grade titanium are base materials; black PVD and rose gold PVD are platings. The catalog lists both, so read them as two facts, not one.

Where the catalog stops — and what to ask

None of the three records supplies care instructions, cleaning guidance, or compatibility notes. That is a gap in the supplied information, not evidence that the products lack such guidance. Before you buy, ask the store for the care information that applies to the specific piece, especially for PVD-plated items where the coating is a separate consideration from the base metal.

The same applies to fit. No record states a recommended wearable length for a given piercing, and inventing one would be guesswork. If you are between sizes on the labret, ask which of the two lengths suits your piercing rather than choosing by appearance.

Which piece fits which decision

• Choose the 316L surgical steel screw-on plug if: You already know your gauge is 2Ga, you want a solid screw-on plug with a shell centre, and you are comfortable ordering per piece. Accept that length is not confirmed in the record.
• Choose the titanium threadless labret if: You need a flat back and a decorative top, you can confirm your gauge and length combination, and you want the implant-grade titanium alloy named in the listing.
• Choose the internally threaded nipple jewellery if: Your piercing takes 14ga at 14mm and you prefer a piece where both dimensions are stated. It is the least ambiguous sizing record of the three.
