Screws can be supplied with pan head, countersunk head, round head, cheese head, slotted drive, Phillips drive, hex socket, Torx, or customer-specified designs according to drawings or samples. Metric and inch threads are available upon request, with brass grades, surface finish, tolerance, packing method, and inspection requirements reviewed before production. Brass machine screws can be supplied for electronics, instruments, terminals, panels, furniture hardware, and equipment assembly.
Brass screws can be produced as standard machine screws or custom fasteners according to drawing, sample, or project specification.
Quick Specs
What Buyers Should Know Before Sourcing Brass Machine Screws
Brass machine screws are commonly selected for electrical contact areas, decorative assemblies, corrosion-resistant indoor hardware, and applications where magnetic response should be low. Buyers should confirm the head style, drive style, thread, length measurement method, brass grade, and finish before requesting a quotation.
For non-standard parts, drawings are especially important because brass screws may involve custom head height, reduced shank, special slot width, shoulder design, knurling, or plated finish. XZ Fastener can review custom fasteners made to drawing when standard screw dimensions do not match the assembly.
Key purchasing checks
- Confirm screw standard, head type, drive type, thread diameter, pitch, and length.
- Specify the brass material grade or required performance properties.
- Define whether the screw is for electrical contact, appearance, corrosion resistance, or general fastening.
- Confirm finish, plating thickness, surface color, and anti-tarnish requirement.
- State packing, label, inspection, and sample approval requirements before production.

Material and Grade Explanation
Brass machine screws are typically selected for corrosion resistance in indoor or mild environments, electrical conductivity, machinability, and decorative appearance. Common brass descriptions include H59, H62, C26000, C27000, and C36000. Some applications may require lead-free brass or a specific copper-zinc composition according to order requirement.
Brass is softer than many carbon steel or stainless steel fasteners, so buyers should confirm tightening torque, thread engagement length, and mating material. If higher mechanical strength is required, carbon steel or stainless steel screws may be more suitable. For small precision parts, XZ Fastener’s guide to small screws and custom components can support specification review.
Material selection reminders
- Use brass where electrical conductivity, appearance, or low magnetic response matters.
- Confirm lead-free brass if the product or market requires it.
- Check whether free-cutting brass is suitable for machined custom screws.
- Review torque carefully because brass is softer than steel.
- Confirm mating material to reduce thread damage or galvanic corrosion risk.
Surface Finish Selection Guide
Plain brass
Suitable when natural brass color and basic corrosion resistance are acceptable. Color variation should be discussed for visible parts.
Polished brass
Used for decorative hardware, instrument panels, furniture fittings, and visible assemblies where appearance matters.
Nickel plated
Common for a bright silver appearance, improved wear surface, and controlled finish consistency in equipment hardware.
Tin plated
Can be used for electrical contact applications where solderability or contact behavior is important.
Chrome plated
Available upon request for decorative or surface protection requirements after confirming appearance and thickness needs.
Anti-tarnish treatment
Can be reviewed for brass screws that require cleaner appearance during storage, transport, or display assembly.
For finish inspection details such as thickness, adhesion, and surface checks, buyers can review XZ Fastener’s custom fastener coating inspection guidance before confirming plated brass screw orders.
Manufacturing and Quality Control
Brass machine screws can be produced by cold forming, machining, thread rolling, thread cutting, drive forming, slotting, polishing, plating where required, sorting, and packing. The route depends on screw size, brass grade, quantity, head shape, drive style, and tolerance requirement.
Quality control can include diameter, pitch, length, head height, head diameter, drive fit, thread fit, surface color, plating thickness, burr condition, and packing accuracy. For threaded parts, go/no-go thread gauge testing can be arranged according to order requirement.
Applications
- Electrical terminals, switchgear, connectors, and contact assemblies
- Electronics hardware, control boxes, meters, and instrument panels
- Decorative hardware, furniture fittings, and visible fastening points
- Machinery covers, nameplates, panel boards, and light equipment assemblies
- OEM kits, repair packs, and custom brass hardware sets
Brass machine screws are widely used where a steel screw may not meet conductivity, appearance, or magnetic response requirements. For electronics purchasing, XZ Fastener’s electronics screw and hardware selection guide can help buyers check screw type, material, size, and packing details.
For custom brass assemblies, provide drawings or samples early so head style, thread, drive, finish, and inspection points can be confirmed before tooling or sample production.
