You're looking at bulk hardware pricing probably, so let's cut to teh chase — we move these by thousand, MOQ is 1000 pieces, and the WSDHML828A flush bolt dimensions are 43×38×38 mm, though we can tweak that if you need something slightly different.

It's basically a friction stay flush bolt combo built for window/door application, and it handles anti-theft Grade A standard so residential or commercial projects are both fine — though honestly, it's overkill for lightweight interior doors, good to know that.

3, we use aluminun alloy, zinc alloy, and stainless steel in the same unit (the steel takes the load), and finishing options are pretty standdard: anodized, powder coating, or polishing — most buyers go with powder coating for exterior use, it's more durable long-term.


2-year warranty comes as is, and our company have ISO9001 certification on file if your compliance team needs that — just ask for the COA with your order, we usually have stock.

Lead time runs about 10-20 days, give or take, and packaging is carton-based (customizable if you want branding, but we'll need to confirm minimums for that) — shippng via sea is typical for these volumes, HS code is 8302410000.

One thing we've noticed: the zinc alloy parts in the assembly hold up better than some cheaper alternatives in humid climates, so it's actually a decent choice for coastal buildings.
