It features an M20 x 2.50 thread profile with a 220 mm (approximately 8.66 inches) length under head, providing substantial grip in heavy assemblies. The fastener is manufactured from alloy steel to material grade 12.9, the highest standard tensile strength class for metric socket cap screws, and finished with a black oxide coating that offers mild corrosion resistance and a low-reflectance surface. The hex drive socket accepts a standard hex key for installation. This screw is sold individually and is appropriate for professional mechanical, industrial, and trade applications requiring precision metric fastening.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in structural mechanical assemblies, machine frames, equipment mounting, and industrial maintenance where high clamping force and dimensional precision are required. The partial thread configuration allows for full engagement of the shank in clearance holes before threading into the mating component, which is common in bolted joint assemblies with a clamped member. Grade 12.9 alloy steel construction makes it appropriate for applications with high tensile load requirements where fastener failure is not acceptable. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, ensuring dimensional and mechanical property compliance across metric fastening applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20 x 2.50 thread size with 220 mm (approximately 8.66 inches) length under head\u003c\/li\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction for maximum tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise bolted joint clamping\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectance\u003c\/li\u003e\n  \u003cli\u003eHex socket drive compatible with standard hex keys and socket tooling\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit metric hex socket cap screw for applications requiring M20 x 2.50 thread engagement in compliance with ISO 4762 and ANSI B1.13M dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate hex key or socket drive rated for grade 12.9 fasteners. Verify mating thread condition and ensure clearance holes are sized correctly for the M20 shank diameter before assembly. Do not substitute a lower-grade fastener in applications specified for grade 12.9.
