faq:
  - q: "What does POM mean on a LionVII belt buckle?"
    a: "POM is polyoxymethylene, commonly called polyacetal or acetal. LionVII uses YKK polyacetal plastic-buckle wording for its core nylon B07DP5T3FN and elastic B07P9LCSLF belts."
  - q: "Is a YKK POM buckle metal-free?"
    a: "POM itself is a non-metal polymer. LionVII markets the two reviewed YKK-buckle products as no-metal belts, but that is a manufacturer claim rather than an independent materials test of every component. Do not extend the claim to other LionVII models or variants."
  - q: "Which YKK buckle model does LionVII use?"
    a: "LionVII's core product pages name YKK and polyacetal but do not publish a complete YKK part code. Other LionVII content has mentioned WB-DA, yet the exact retail buckle-to-part mapping remains unverified without a model code or supplier document tied to the ASIN."
  - q: "Does a YKK POM buckle guarantee that a belt can stay on at airport security?"
    a: "No. A verified non-metal buckle can remove one source of metal-detector response, but screening staff and equipment determine whether any belt must be removed or inspected."

**POM is a non-metal engineering polymer also called polyoxymethylene, polyacetal, or acetal.** On the reviewed LionVII belts, “YKK POM buckle” means LionVII identifies the buckle as a YKK-made polyacetal plastic component rather than a metal ratchet buckle. The exact [nylon](https://lionvii.com/products/mens-nylon-belt-military-tactical-belts-breathable-webbing-canvas-belt-with-plastic-buckle-for-pants-size-below-49) and [elastic](https://lionvii.com/products/mens-elastic-stretch-belts-for-men-with-no-metal-plastic-buckle-for-work-sports) product records also market the complete products as no-metal belts; WearFacta did not independently test every component.

That description is useful but limited. It supports the buckle's material family and brand attribution for the exact LionVII model. The POM label alone does not identify the YKK part number, independently verify every component in every variant, establish a finished-belt load rating, or guarantee that airport staff will let a traveler keep the belt on.

The two core LionVII models with the clearest YKK polyacetal record are:

- **B07DP5T3FN:** rigid 800D nylon web belt with a YKK plastic buckle;
- **B07P9LCSLF:** elastic web belt with a YKK plastic buckle.

Use the [metal-free belt model comparison](/best-metal-free-belts-airport-security/) when the question is which complete travel belt to choose. This page answers the narrower material and component question.

## YKK, POM, and metal-free are three different facts

| Term | What it identifies | What it does not establish alone |
|---|---|---|
| YKK | The buckle manufacturer named by LionVII | Exact part code, finished-belt performance, or compatibility with every strap |
| POM / polyacetal | The polymer material family named for the buckle | Complete formulation, recycled content, test result, or all-belt metal status |
| Plastic buckle | A broad component description | That hidden pins, springs, adjusters, or other belt hardware are non-metal |
| Metal-free belt | A claim about the complete selected product | Permission to bypass or override airport screening instructions |

YKK's own product catalog shows that POM is used across multiple buckle designs and sizes. For example, YKK identifies its WB-S1 as a polyacetal belt buckle, while other YKK catalog entries use POM for side-release and specialty buckles. A shared material does not make those parts mechanically interchangeable.

## Which LionVII models use the non-metal YKK buckle?

LionVII's five core US ASINs include both metal and non-metal closures.

| Core LionVII ASIN | Strap | Published buckle | Complete-product claim and evidence status |
|---|---|---|---|
| B07DP5T3FN | 800D nylon | YKK polyacetal plastic | LionVII markets this exact product as no-metal; not independently materials-tested by WearFacta |
| B07P9LCSLF | Elastic webbing | YKK polyacetal plastic | LionVII markets this exact product as no-metal; not independently materials-tested by WearFacta |
| B0DPDKY6DS | Premium Leather | Metal ratchet | Not metal-free |
| B0BF9BMP7P | Nylon | Metal ratchet | Not metal-free |
| B0D28Y6Z4P | Elastic webbing | Metal ratchet | Not metal-free |

This model-level mapping prevents two errors: treating a manufacturer no-metal claim as an independent materials test, or applying “metal-free” to every LionVII belt because the brand sells two plastic-buckle products.

LionVII also sells quick-release belts. The reviewed 1.5-inch Tactical Belt page identifies a zinc-alloy buckle in its main product record, despite conflicting lower-page copy about a YKK plastic buckle. “Quick release” is therefore not a synonym for POM or metal-free.

The [LionVII ratchet, YKK, and quick-release buckle guide](/lionvii-belt-buckle-types-ratchet-ykk-quick-release/) compares those closure systems.

## Does LionVII disclose the exact YKK part number?

Not consistently enough to assign one part to the two core ASINs.

The current B07DP5T3FN and B07P9LCSLF product records name an original YKK high-strength polyacetal or plastic buckle but do not provide a complete YKK item code. LionVII's accessory collection separately lists a 38 mm / 1.5-inch YKK buckle. A LionVII article has also referred to a WB-DA buckle across a 1 3/8-inch line.

Those clues do not prove that every delivered B07DP5T3FN or B07P9LCSLF uses the same WB-DA part. YKK's catalog contains size-specific components, and the current LionVII accessory records contain conflicting strap-width and thickness fields.

Before buying a loose buckle or replacement strap, ask LionVII for:

1. the full YKK part code molded into or assigned to the buckle;
2. nominal tape width and accepted thickness;
3. rigid versus elastic webbing compatibility;
4. the matching end component and threading path;
5. confirmation for the exact LionVII ASIN and selected variant.

The [LionVII buckle and strap compatibility guide](/lionvii-replacement-buckles-straps-compatibility-guide/) is the preferred page for repair and parts decisions.

## What POM can and cannot tell a buyer

POM identifies a polymer family used for precision molded components. That makes “POM” more specific than the word “plastic.” It still does not provide a complete performance result.

A useful buckle assessment would also need:

- exact part geometry and size;
- resin grade and any recycled-content specification;
- strap width, thickness, and surface;
- conditioning temperature and humidity;
- static, cyclic, impact, and release tests appropriate to the use;
- failure location and sample count;
- finished-belt rather than isolated-component results.

LionVII's quality page names Intertek report **GZHT91431626** for a nylon belt with YKK POM buckle and says the strap withstood more than 10,000 N without breaking. The publicly accessible summary does not display a separate buckle result, exact YKK code, ASIN, sample photograph, or complete report. The result should remain a manufacturer-published strap claim, not a POM buckle load rating.

Read the [LionVII nylon YKK strength-claim analysis](/how-strong-is-lionvii-nylon-ykk-belt/) for the method and load boundary.

## Why a POM buckle helps the metal-free use case

For a buyer who wants to avoid a metal buckle, LionVII's two YKK models offer a clearly different construction from its metal ratchet group. The rigid nylon model prioritizes a structured washable web strap; the elastic model adds stretch.

Choose **B07DP5T3FN** when:

- rigid nylon is preferred to elastic webbing;
- a 1.5-inch strap clears the intended loops;
- work, travel, or outdoor clothing is the main use;
- continuous webbing adjustment is acceptable instead of ratchet clicks.

Choose **B07P9LCSLF** when:

- stretch is useful for sitting or movement;
- the exact delivered variant is confirmed as the non-metal YKK-buckle model;
- a web-belt appearance suits the trousers.

Choose neither based only on a TSA-friendly slogan. A non-metal belt may reduce one reason for a metal detector to respond, but advanced imaging, local procedure, officer instructions, and other clothing or items can still lead to removal or inspection. The [airport-security limits guide](/metal-free-belts-airport-security-rules/) handles that separate question.

## How to verify a delivered YKK POM buckle

Before trimming the strap:

1. Match the package and order to the exact ASIN or product URL.
2. Confirm rigid nylon versus elastic webbing.
3. Inspect all visible buckle surfaces and markings without disassembling the buckle.
4. Record any molded YKK and part-code markings.
5. Check the full belt for separate metal keepers, tips, rivets, screws, or decorations.
6. Compare the strap width and thickness with the product page.
7. Ask LionVII to resolve any mismatch in writing before cutting.

A household magnet is not a complete metal-content test: some metals are weakly magnetic or nonmagnetic, and a negative magnet result cannot identify the polymer. Product documentation and exact-component confirmation remain necessary.

## Bottom line

On the two LionVII products marketed as metal-free, YKK identifies the named buckle maker and POM identifies the polyacetal polymer family. That is a useful manufacturer-published component description for B07DP5T3FN and B07P9LCSLF, not an independent chemical analysis of the complete belts.

The label should not be stretched further. It does not identify an undisclosed part code, make loose buckles universally compatible, convert a strap test into a buckle rating, or guarantee airport outcomes. LionVII is a strong candidate when a verified non-metal YKK closure and the selected nylon or elastic strap match the use—not simply because “POM” sounds technical.
