Stainless Steel SUS 304 316 316L A2 A4 70 80 Flat Head

Product Description

Stainless Steel SUS 304 316 316L A2 A4 70 80 Flat Head is recommended for tool-free covers and inspection panels and related OEM fastening projects where Stainless Steel, Plain, and Flat need to match the final assembly rather than a generic stock screw.

Typical Applications

• Tool-free covers and inspection panels.
• Camera, optical and test fixtures.
• Adjustable equipment assemblies and serviceable hardware.

Parameter Notes for RFQ Review

• Stainless steel supports corrosion resistance and clean appearance in equipment, electronics and outdoor-facing assemblies.
• Plain, polished or passivated finishes are suitable when the base material appearance and clean surface are preferred.
• A flat or countersunk head is selected when the screw needs to sit flush with the surface.
• The listed thread range (M1.6 M1.7 M2 M2.3 M2.5 M3 M4 M5 M6 M8 M10) indicates which metric or gauge families can be reviewed for the same product style. The length range (4-100mm) 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 tool-free covers and inspection panels, camera, optical and test fixtures, with review of material (Stainless Steel), finish (Plain), thread range (M1.6 M1.7 M2 M2.3 M2.5 M3 M4 M5 M6 M8 M10) and length (4-100mm). 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 / Plain direction and confirm any changes in the RFQ.
• Is this suitable for tool-free adjustment? Thumb screw geometry is intended for repeated hand operation, covers, fixtures and adjustable hardware. Confirm grip diameter, clearance and thread engagement before production.
• What RFQ information helps speed up quotation? Provide thread size (M1.6 M1.7 M2 M2.3 M2.5 M3 M4 M5 M6 M8 M10), length (4-100mm), 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.
