When you're assembling a 3D printer, mounting an electronics enclosure, or fastening a bracket in a tight space, the last thing you want is to fumble with a separate washer. These flanged button head machine screws solve that problem with an integrated flange that acts as a built-in washer — spreading the clamping load over a wider area, preventing pull-through in soft materials, and saving you assembly time and parts.
Made from carbon steel with a choice of nickel plating (bright silver) or black zinc plating (matte black), these screws offer reliable corrosion resistance for indoor and light outdoor use. The low-profile button head sits neatly above the surface without snagging, and the Phillips cross drive works with standard #1 or #2 Phillips screwdrivers and power bits. Available in M2, M2.5, M3, M3.5, M4, M5, and M6 diameters, with lengths from 3mm to 50mm (measured under the head).
Ideal for 3D printer frames and panels, electronics enclosures, automotive interior trim, furniture assembly, appliance repair, and any DIY or light industrial application where a wide bearing surface and clean low-profile finish are required. Select your size and pack quantity above.
Frame assembly, panel mounting, and electronics enclosures where M3 and M4 flanged screws are the standard fastener. The integrated flange prevents pull-through in printed plastic parts without needing a washer.
PCB standoffs, enclosure panels, and equipment housings where a low-profile head and wide bearing surface are needed. M2 and M2.5 sizes are ideal for miniature electronics work.
Dashboard panels, trim clips, and interior fittings where a clean, low-profile head finish is required. Black zinc plating blends naturally with dark interior components.
Furniture assembly, appliance repair, workshop jigs, and general fastening tasks where metric machine screws with a wide bearing surface simplify assembly and reduce part count.

A flanged button head screw has an integrated washer-like flange directly under the head. This flange distributes clamping pressure over a larger area, reducing the risk of the head pulling through soft materials like plastic or thin sheet metal. It also eliminates the need for a separate flat washer, saving assembly time and reducing part count. The button head itself is lower profile than a pan head, making it ideal for applications with limited clearance.
These are machine screws — they are designed to thread into pre-tapped holes or be used with a matching metric nut. They will not cut their own threads. For use in plastic or soft materials without a tapped hole, use a threaded insert or a nut on the back side for best results.
Nickel plating produces a bright, silver-colored finish with good corrosion resistance — commonly used for visible applications where a clean, polished appearance matters. Black zinc plating produces a matte black finish that blends well with dark equipment and also provides good rust protection. Both finishes are suitable for indoor use and light outdoor exposure. Neither is as corrosion-resistant as stainless steel, but both are cost-effective for most DIY and light industrial environments.
Length is measured from the underside of the flange (the flat bearing surface) to the tip of the screw. The flange and button head height are not included in the stated length. For example, an M3 × 10mm screw has 10mm of threaded shank below the flange.
Use a standard metric coarse-thread nut of the same diameter: M2 nut for M2 screws, M3 nut for M3 screws, and so on. Thread pitches are standard coarse: M2 (0.4mm), M2.5 (0.45mm), M3 (0.5mm), M3.5 (0.6mm), M4 (0.7mm), M5 (0.8mm), M6 (1.0mm). These are widely available at hardware stores.
Yes — carbon steel is ferromagnetic, so these screws are strongly magnetic. A magnetic screwdriver or bit will hold them securely, which is especially useful when working in tight spaces or overhead where dropping a screw is a concern.
For M2 and M2.5 screws, use a #1 Phillips (PH1) bit. For M3 through M6 screws, use a #2 Phillips (PH2) bit. Always use a well-fitting, sharp bit to minimize cam-out and avoid damaging the head, especially at higher torque levels.
