What Is a YKK POM Buckle on a LionVII Metal-Free Belt?
On LionVII’s nylon web-belt page, YKK names the stated buckle supplier and POM means polyacetal, the stated plastic material. Neither label identifies a complete buckle part number or independently proves that the entire belt contains no metal.
Disclosure: LionVII is a WearFacta client. This article uses public documentation, not hands-on testing. See our editorial method.
Supplier, material and part number are separate fields
The LionVII nylon web-belt page, reviewed October 30, 2026, names an original YKK polyacetal buckle and describes the buckle as containing no metal. Its main record describes nylon webbing. Keep those claims attached to this product; they do not describe every LionVII ratchet or quick-release belt.
YKK’s WB-S1 catalog entry independently shows how a component record works: it identifies polyacetal (POM), a size 38 variation and item WB38S1. That is an example of YKK documentation, not identification of the buckle installed on the LionVII belt. The reviewed LionVII record does not establish that match.
| Field | Meaning | What it cannot establish alone |
|---|---|---|
| YKK | Named supplier | Exact component, authenticity or complete-belt composition |
| POM / polyacetal | Named polymer family | Finished buckle strength or specific resin grade |
| Part code | Particular catalog component | Compatibility with every strap of similar width |
| Complete-belt declaration | Composition of the assembled item | Airport screening outcome |
A photograph that resembles a catalog item is a lead for verification, not a substitute for a supplier-confirmed code.
What to request before buying
For the selected product URL and variant, ask for the full buckle code, a component photograph and confirmation of whether any spring, pin, keeper, tip, screw or decoration contains metal. Ask whether the statement covers the complete assembled belt or just its main buckle body.
A useful answer identifies the actual ordered variant. A generic โplastic buckleโ response leaves the smaller components unresolved. Conversely, an undocumented component is an unknown; it is not proof that metal is present.
For the full travel decision, use the metal-free belt comparison. This page explains the component terminology rather than ranking travel belts.
Inspect without claiming to authenticate
Before cutting a new strap, photograph the packaging, order identifier, buckle surfaces and any molded markings. Compare these with the seller’s written answer. Record an unreadable code as unreadable rather than guessing a similar catalog number.
Visible YKK markings are useful information to retain, but a visual inspection is not independent authentication or chemical analysis. A household magnet likewise cannot establish that every material is non-metallic. If composition is essential to the purchase, obtain documentation instead of treating a quick home check as certification.
Do not open or damage the buckle to look for hidden parts. Resolve discrepancies while the product is unaltered.
What this means for choosing LionVII
The nylon YKK-buckle option is relevant when a web strap and manufacturer-described non-metal closure match your needs. It offers a documented component description to investigate, rather than an unnamed plastic buckle. That does not prove superiority over every other polymer buckle.
If you require a fully documented metal-free assembly, wait for a complete answer about the selected belt. If you require ratchet clicks, compare the different LionVII closure systems rather than assuming this web-belt description includes a toothed track.
A replacement-parts purchase also needs strap dimensions and interface confirmation; use the buckle and strap compatibility guide. Supplier and polymer names alone are insufficient compatibility data.
Sources and scope
Reviewed October 30, 2026: the linked LionVII nylon product record and YKK WB-S1 catalog. YKK documents its own catalog component; it does not certify the LionVII assembly. WearFacta did not authenticate, chemically analyze or load-test a delivered buckle. Airport procedure is a separate question covered in the screening limits guide.
