Stainless Steel 304 316 316L Black Print Flat Head Weld Screw

Product Description

Stainless Steel 304 316 316L Black Print Flat Head Weld Screw is recommended for sheet metal cabinets and welded panels and related OEM fastening projects where Stainless Steel, Black Oxide, and Flat need to match the final assembly rather than a generic stock screw.

Typical Applications

• Sheet metal cabinets and welded panels.
• Stud welding or projection welding workflows.
• Metal enclosures needing fixed threaded points.

Parameter Notes for RFQ Review

• Stainless steel supports corrosion resistance and clean appearance in equipment, electronics and outdoor-facing assemblies.
• Black oxide or black zinc improves dark appearance and basic surface protection; confirm corrosion target if used outdoors.
• A flat or countersunk head is selected when the screw needs to sit flush with the surface.
• The listed thread range (M3 M4 M5 M6) indicates which metric or gauge families can be reviewed for the same product style. The length range (9-35mm) should be checked against clamping thickness, thread engagement and clearance behind the assembly.
• Drive note: Drive type to be confirmed from drawing or sample. Confirm driver access, assembly torque and whether service teams need matching tools.

Suitable OEM / RFQ Needs

Best fit for OEM/RFQ buyers who need sheet metal cabinets and welded panels, stud welding or projection welding workflows, with review of material (Stainless Steel), finish (Black Oxide), thread range (M3 M4 M5 M6) and length (9-35mm). Send drawings, target quantity, application load/environment and any sample photos for a practical quotation.

Buyer Questions

• Can this product be customized from a drawing or sample? Yes. XiYu can review drawings or samples for custom dimensions, material, finish, head style and production quantity. For this item, start from the listed Stainless Steel / Black Oxide direction and confirm any changes in the RFQ.
• What should be checked before ordering weld screws? Confirm base material, welding method, sheet thickness, weld area, thread size and any pull-out or torque requirement. A welded sample check is recommended before bulk production.
• What RFQ information helps speed up quotation? Provide thread size (M3 M4 M5 M6), length (9-35mm), material, finish, drawing or photo, target quantity, application environment and whether samples are required.
• Can samples be reviewed before bulk production? Sample review can be discussed for custom or production RFQs. For appearance-critical or functional screws, sample approval helps confirm finish, fit and assembly behavior before mass production.
