Phillips and hex drives are everywhere — but they’re not always the right choice. Precision instruments, electrical terminal blocks, legacy industrial equipment, and vintage electronics often specify a slotted (flat) drive for a reason: fine torque control, easy visual inspection, and compatibility with a simple flat-blade screwdriver. These brass slotted cheese head machine screws in M2 combine the traditional slotted drive with the properties that make brass the preferred material for electrical and precision fastening — electrically conductive, non-magnetic, and corrosion-resistant.
The cheese head profile provides a cylindrical head with a flat top and vertical sides — a larger bearing surface than a pan head, with a defined head height that suits recessed housings and terminal block assemblies. Available in M2×8mm (0.31”) and M2×12mm (0.47”), each sold in a pack of 50 pieces.
Typical applications include electrical terminal block and connector fastening, precision instrument and gauge assembly, vintage electronics and radio equipment repair, scientific and laboratory instrument maintenance, and any application specifying M2 brass slotted cheese head fasteners.

A cheese head screw has a cylindrical head with a flat top and vertical sides, resembling a round of cheese. It provides a larger bearing surface than a pan head and a taller, more defined profile — making it easy to grip and suitable for applications requiring a specific head height above the surface, such as terminal blocks and recessed instrument housings.
Slotted (flat) drive is the traditional standard for precision instruments, electrical terminals, and vintage equipment. It allows fine torque control with a simple flat-blade screwdriver, is easy to inspect visually, and is the specified drive type for many legacy and precision applications where Phillips or hex drives are not appropriate or available.
Brass is electrically conductive, non-magnetic, and corrosion-resistant. It is the preferred material for electrical terminal connections, precision instruments, and applications where magnetic fasteners would cause interference or where conductivity is required. Brass also resists galvanic corrosion when used with copper or brass terminals.
A flat-blade (slotted) precision screwdriver sized to fit the M2 screw slot. Apply moderate torque only — brass is softer than steel and the slot can strip if overtightened or if an oversized blade is used. A quality precision screwdriver set with multiple blade widths is recommended.
Brass provides good corrosion resistance in most indoor environments. It does not rust (iron-based corrosion) but can develop a natural patina over time. For marine or highly corrosive environments, stainless steel or marine-grade brass is recommended. These screws are well-suited for indoor precision and electrical applications.
Yes — these are machine screws, not self-tapping. They require a pre-tapped M2 hole or a matching M2 metric nut. They will not cut their own thread into plastic or metal.
Each size is sold in a pack of 50 pieces. Available in M2×8mm (0.31”) and M2×12mm (0.47”). Select your preferred length using the Size option above.
