When assembling precision instruments, optical devices, PCBs, or miniature mechanical components, standard hardware-store screws simply don't cut it. The wrong material causes galvanic corrosion, the wrong head profile won't seat properly in recessed holes, and oversized fasteners can damage delicate housings. Engineers, hobbyists, watchmakers, and electronics technicians who work with sub-M3 fasteners know how hard it is to source the right brass slotted cheese head machine screws in small, manageable quantities.
Each pack contains brass slotted cheese head machine screws conforming to DIN 84 (ISO 1207), available in diameters from M1.2 to M3 and lengths from 2mm (≈5/64") to 10mm (≈13/32"). Packs are offered in 100 or 200 pieces per order. The cheese head profile — a cylindrical head with a flat top and vertical sides — provides a deep, precise slot engagement and a clean, low-profile appearance in recessed or countersunk assemblies. Material is brass, offering natural corrosion resistance, non-magnetic behavior, and good compatibility with copper and brass mating components.
These DIN 84 brass machine screws are commonly used in precision instrument assembly, electronics enclosure fastening, optical equipment and camera body hardware, model engineering, and decorative or architectural metalwork where a polished brass finish is desired. The slotted drive is the standard specified in many legacy engineering drawings and repair manuals, making these screws an essential stock item for repair technicians and instrument makers.

A general guideline is to select a length that provides at least 1.5× the screw diameter of thread engagement in the base material. For example, an M2 screw threading into a brass insert would typically need at least 3mm of engagement. Available lengths in this listing range from 2mm (≈5/64") to 10mm (≈13/32"). Measure your panel thickness and add the required engagement depth before selecting your size.
These screws are made from brass, a copper-zinc alloy known for its corrosion resistance, electrical conductivity, and non-magnetic properties. Brass is commonly used in precision instruments, electronics, and applications where galvanic compatibility with brass or copper components is important. Contact us to confirm the specific alloy grade if needed for engineering documentation.
Brass generally offers good corrosion resistance in mild outdoor environments and does not rust like steel. However, in marine or highly corrosive environments, brass can be susceptible to dezincification over time. For demanding outdoor applications, consider whether a higher-grade alloy or additional protection is needed.
These screws conform to DIN 84 (equivalent to ISO 1207) and use ISO metric threads (M1.2, M1.4, M1.6, M2, M2.5, M3). They are compatible with standard metric nuts, brass threaded inserts, and tapped holes machined to ISO tolerances. They are not compatible with UNC/UNF inch-standard threads.
A cheese head screw has a cylindrical head with a flat top and vertical sides, resembling a small wheel of cheese. Compared to a pan head, the cheese head is taller and narrower, providing a deeper slot for the screwdriver and a more precise fit in recessed holes. It is the head style specified in DIN 84 and is commonly used in precision instrument and electronics assembly.
These screws use a straight slotted drive. For M1.2–M1.6, a precision flat-head screwdriver with a blade width of typically 0.8–1.0mm is generally appropriate. For M2–M3, a standard flat-head screwdriver with a 1.0–1.5mm blade is typically used. Using a correctly sized blade prevents slot damage and cam-out during installation.
Brass machine screws are generally softer than steel and are not intended for high-load structural applications. They are well suited for light-duty fastening in precision instruments, PCBs, optical equipment, and decorative assemblies where corrosion resistance and non-magnetic properties matter more than tensile strength. For load-bearing applications, consult a fastener engineer and confirm the material grade with us before ordering.
