It features a low-profile button head driven by a 5mm hex socket. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this fastener is fully threaded and carries a hardness rating of 38 HRC. It meets ANSI\/ASME B18.3 and ASTM F835 standards. The combination of high tensile strength and corrosion-resistant finish makes it suited for precision mechanical assemblies where a flush, low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in applications where standard hex cap screw head heights would interfere with mating components or enclosures. Typical installations include machine housings, brackets, fixtures, and structural joints in industrial and mechanical equipment. The right-hand thread and metric sizing make it compatible with tapped holes conforming to metric thread standards. The black oxide finish provides moderate corrosion resistance in protected environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction for high tensile load capacity\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance in indoor and protected applications\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head at 14.0mm diameter and 4.4mm height reduces interference in tight assemblies\u003c\/li\u003e\n  \u003cli\u003e5mm hex socket drive for precision torque application\u003c\/li\u003e\n  \u003cli\u003eFully threaded with right-hand M8x1.25 metric thread\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use metric fastener for any M8x1.25 tapped hole application requiring a button head profile and Grade 12.9 strength class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical or maintenance technicians using a 5mm hex socket or hex key. Ensure the mating threaded hole is clean and free of debris before driving the screw. Do not exceed the rated strength class by applying impact tooling without proper torque control.
