These M5–M10 button head socket cap screws in A2 304 stainless steel solve both problems — a low-profile domed head that clears covers and guards, sold in quantities as small as 1 piece, so engineers, fabricators, 3D printer builders, and DIYers can get exactly what they need without overstocking.\u003c\/p\u003e\n\u003cp\u003eEach screw is a single button head socket cap screw machined from A2 304 stainless steel (18\/8 chromium-nickel alloy), with a hex socket (Allen key) drive and ISO metric coarse thread. Available in four diameters — M5, M6, M8, and M10 — with shank lengths from 8mm (≈5\/16\") to 80mm (≈3-1\/8\") depending on diameter. Note: length is measured excluding the head, per ISO 7380 standard. Sold in packs of 1, 2, 5, 10, or 20 pieces.\u003c\/p\u003e\n\u003cp\u003eTypical applications include securing panels, covers, and guards on CNC machines, 3D printers, and aluminum extrusion frames where a low-profile button head socket screw provides clearance that a standard cap screw cannot; fastening equipment enclosures, junction boxes, and access panels in light fabrication and electrical work where a stainless hex drive bolt delivers a clean, corrosion-resistant finish; and general-purpose metric fastening in furniture, bicycles, and DIY builds where individual piece purchasing lets you match the exact size and quantity needed without waste.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔵\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e ISO metric coarse thread — M5 (0.8mm pitch), M6 (1.0mm pitch), M8 (1.25mm pitch), M10 (1.5mm pitch).

This is standard for button head screws (ISO 7380). For example, an M6 × 20mm button head screw has a 20mm shank below the head.

This makes button head screws ideal for applications where clearance above the surface is limited, or where a smooth, rounded appearance is preferred.

Note that button head screws generally have a lower torque rating than standard socket cap screws of the same diameter due to the shallower hex socket. They are suitable for general-purpose fastening, light structural connections, and panel assembly.
