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 pan, round or button head provides a visible bearing surface and is easier to inspect after assembly.
• The listed thread range (M1.6 M1.7 M2 M2.2 M2.5 M3 M3.5 M4 M4.2 M4.8 M5 M6 M8) indicates which metric or gauge families can be reviewed for the same product style. The length range (8-20mm) 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.
