2-56 x 5/8 Alloy Steel Button Head Socket Cap Screw is commonly specified when designers need internal-hex access with a broad, finished head profile. The alloy steel construction supports manufacturing equipment where a smooth button head and socket engagement are required.
It is commonly used on machine covers and service panels where the finished head appearance is useful on exposed equipment. It is also suited to control enclosures and equipment housings when the rounded head reduces sharp edges on handled surfaces. The button-head form is specified when the fastener head remains visible or accessible and a smooth rounded profile is preferred.
For assemblies specified with 2-56 thread and 5/8 in. length, the reference head diameter is 0.154-0.164 in. and the head height is 0.038-0.046 in. The nominal body diameter and hex-key information below help maintenance and purchasing teams verify fit and tool access.
Reference dimensions may vary slightly by manufacturer.
