This fully threaded fastener is manufactured from Grade 8.8 steel and left uncoated with a bright finish, making it suitable for use in controlled environments where a bare steel surface is acceptable. The M8 x 1.25 thread pitch and 28 mm length under the head make this screw a standard metric size commonly stocked in maintenance, manufacturing, and trade settings. Installation is performed using a 13 mm hex wrench or socket. It conforms to DIN 933 and ISO 4017 standards.\u003c\/p\u003e\u003cp\u003eThis screw is used across a wide range of industrial, commercial, and mechanical installation scenarios. Typical applications include equipment assembly, machinery maintenance, HVAC unit mounting, and general structural fastening where metric hardware is specified. The fully threaded shank provides thread engagement along the entire shaft length, which is useful in through-bolt applications or when threading into deeper tapped holes. Minimum order quantity is 100 pieces, and the package quantity is 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 metric thread size, fully threaded shank\u003c\/li\u003e\n\u003cli\u003e28 mm length under head per DIN 933 and ISO 4017 standards\u003c\/li\u003e\n\u003cli\u003eGrade 8.8 steel construction for reliable tensile and yield strength\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for bare steel appearance\u003c\/li\u003e\n\u003cli\u003e13 mm hex drive size compatible with standard metric sockets and wrenches\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 933 and ISO 4017 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric hex head cap screw for use in any application requiring an M8 x 1.25 x 28 mm fully threaded fastener meeting DIN 933 or ISO 4017 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a mechanic, millwright, or qualified tradesperson using a 13 mm socket or open-end wrench.
