Fully threaded along its 20mm length under the head, it is manufactured from Grade 12.9 alloy steel and finished with a blue phosphate coating that provides corrosion resistance and a consistent surface appearance. The hex socket drive accepts a 5mm hex key for installation and removal. This fastener is specified to ISO 7380 standards and is suited for use by mechanical contractors, industrial maintenance technicians, and precision assembly professionals.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in applications where a standard hex cap screw head profile is too tall for the assembly clearance. The button head design distributes clamping load across a wider bearing surface than a standard socket cap screw. Typical install scenarios include machinery panels, equipment enclosures, and structural assemblies where metric fasteners are specified. Full threading along the 20mm shank length allows engagement in a range of thread depths without a grip-length constraint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction provides high tensile and proof load ratings\u003c\/li\u003e\n  \u003cli\u003eButton head profile reduces overall installed height for tight clearance applications\u003c\/li\u003e\n  \u003cli\u003eBlue phosphate finish delivers corrosion resistance and a uniform appearance\u003c\/li\u003e\n  \u003cli\u003eFully threaded 20mm length under head maximizes thread engagement range\u003c\/li\u003e\n  \u003cli\u003e5mm hex socket drive for standard hex key or bit installation\u003c\/li\u003e\n  \u003cli\u003eManufactured to ISO 7380 fastener standard for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric replacement fastener for assemblies specifying M8x1.25 button socket cap screws per ISO 7380.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5mm hex key or socket bit.
