The integrated smooth flange measures 18 mm in diameter, distributing clamp load across a wider area without requiring a separate washer. Manufactured from Grade 10.9 alloy steel with a phosphate and oil finish, this fastener delivers high tensile strength and baseline corrosion resistance suitable for demanding mechanical assemblies. Drive engagement is through a 12.73 to 13.00 mm hex head. This bolt meets DIN 6921 and DIN ISO 898-1 standards, making it appropriate for engineers and maintenance professionals specifying metric hardware to recognized international tolerances.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in mechanical, industrial, and equipment assembly applications where an M8 metric thread is required and a built-in flange is preferred over a separate flat washer. Fully threaded construction makes it well suited for short-grip applications and thin-material clamping. It is commonly installed in machinery fabrication, equipment mounting, and structural assemblies by millwrights, maintenance technicians, and assemblers working to metric fastener specifications. The phosphate and oil finish provides a degree of corrosion protection during storage and in moderately dry service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM8 x 1.25 metric thread, 16 mm length under head, fully threaded\u003c\/li\u003e\n  \u003cli\u003e18 mm smooth flange diameter distributes load without a separate washer\u003c\/li\u003e\n  \u003cli\u003eGrade 10.9 alloy steel for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish for baseline corrosion and galling resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive with 12.73 to 13.00 mm drive size for standard metric wrenching\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6921 and DIN ISO 898-1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard DIN 6921 metric flange bolt for use in any assembly requiring an M8 x 1.25 fully threaded smooth flange bolt conforming to DIN 6921 and DIN ISO 898-1 dimensional and mechanical standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a metric hex wrench or socket sized to the 12.73 to 13.00 mm drive. Verify mating thread condition and clean threads before installation to avoid galling on the alloy steel finish.
