Steel Nail With Flat Head

Steel nail with flat head get treated in a few ways to do their job better. Hot-dip galvanizing dunks them in zinc for a thick rust-proof layer,great for outdoor gear that sits in rain or dirt for years. Electro-galvanized is a lighter, smoother zinc coat, better for indoor furniture where you don’t want rough-looking nails. Epoxy coating fights off chemicals, so factories with harsh stuff use those. Phosphate ones help paint grip better, and stainless steel gives a polished finish for spots where looks matter. Basically, these treatments keep nails from rotting in weather, sun, or beat-up places,so they stay tough wherever you stick them.

Size

Steel nail with flat head come in many sizes,diameters from 0.5mm to 8mm and lengths from 10mm to 300mm to fit all kinds of jobs. You might see them sized by the penny system (like 8d, 16d) or in metric measurements (50mm, 100mm). The shanks (the shaft part) can be smooth, ringed, or spiral,each works better in certain materials, like ringed shanks for gripping wood tighter. The heads also vary: flat, countersunk (so they sit flush), or rounded, which is better for looks or function.If your project requires a specific size or shape, they can be custom made.Just remember to choose nails based on how thick the material is and how much weight they need to hold,that way, they’ll work best.

International Standards

Q:Do the steel nail with flat head produced by Xiaoguo® meet international quality standards such as ASTM or ISO?

A: Our steel nails meet ASTM F1667 (U.S.) and ISO 9001 standards, which means the material is consistent, sizes are accurate, and they perform reliably. We do strict batch testing for hardness, shear strength, and how thick the coating is. You’ll get Certificates of Compliance (COC) and Mill Test Reports (MTRs) to check the quality. For markets like the EU, we make sure they follow REACH rules, avoiding restricted substances like hexavalent chromium.
