Typical Applications

• Electronics and instrument housings.
• Machine panels and brackets.
• Oem hardware assemblies requiring repeatable metric threads.

Parameter Notes for RFQ Review

• Titanium is useful where weight reduction, corrosion resistance and non-magnetic behavior matter.
• Black oxide or black zinc improves dark appearance and basic surface protection; confirm corrosion target if used outdoors.
• A pan, round or button head provides a visible bearing surface and is easier to inspect after assembly.
• The listed thread range (M3 M4 M5 M6 M7 M8) indicates which metric or gauge families can be reviewed for the same product style. The length range (10-100mm) should be checked against clamping thickness, thread engagement and clearance behind the assembly.
• Drive note: Hex socket / Allen drive. Confirm driver access, assembly torque and whether service teams need matching tools.

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 Brass, Stainless Steel, Steel, Aluminium, Plastic, Titanium, Nickel, Iron, Alloy Steel, Carbon Steel, 316 Stainless Steel, Copper, Metal, Bronze, Nylon, 304 Stainless Steel, C1022, 410 Stainless Steel / Black, Zinc, Plain, Black Oxide, Zinc Plated, Nickel Plated, Galvanized, Other, Blue-Dyed, Cadmium Plated, Zinc-Aluminum Coated, Chrome Plated, Zinc-Flake Coated, Silver Plated, Blue Anodized, Phosphate, Anodizing, Plating direction and confirm any changes in the RFQ.
• How should I choose the head and drive style? A pan, round or button head provides a visible bearing surface and is easier to inspect after assembly. Share the mating part, clearance and installation tool so the head and drive can be checked against the assembly.
• What RFQ information helps speed up quotation? Provide thread size (M3 M4 M5 M6 M7 M8), length (10-100mm), 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.
