S-91290A366 M10 x 190 mm DIN 912, ISO 4762, ISO 898-1 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with 170,000 psi tensile strength and Class 12.9 rating for reliable performance in high-stress applications.
• Superior corrosion resistance provided by the black-oxide coating, extending service life in demanding industrial environments.
• Precise hex socket drive with 8mm drive size ensures secure tool engagement and reduces stripping risk during installation.
• Optimized thread design with M10 coarse thread (1.5mm pitch) and Class 6g fit enables quick assembly and vibration resistance.
• Enhanced durability from Rockwell C37 hardness, maintaining structural integrity under repetitive mechanical stress.
• Versatile partial threading along 31mm of the 190mm shaft allows both clamped joint security and unthreaded shaft functionality.
• Global compliance assurance meeting DIN 912, ISO 4762, and ISO 898-1 standards for international project compatibility.

Professional Applications & Engineering Value

This black-oxide alloy steel socket head cap screw delivers critical engineering solutions where failure isn't an option. The Class 12.9 strength rating and 170,000 psi tensile strength directly address structural integrity concerns in heavy machinery, automotive assemblies, and precision equipment. Its M10 coarse thread with 1.5mm pitch provides rapid installation while resisting loosening under vibration - a common industrial challenge. The partially threaded design creates precise clamping zones without compromising unthreaded shaft sections for alignment or sliding components. Combined with the black-oxide surface treatment, it withstands corrosive environments that degrade ordinary fasteners, making it ideal for manufacturing equipment, construction machinery, and transportation systems requiring metric socket head cap screws with proven reliability.

Specification Summary & Compliance

Manufactured to Class 6g thread tolerance with ISO metric coarse threading (M10 x 1.5mm), this fastener guarantees dimensional accuracy per DIN 912/ISO 4762 specifications. The 190mm length includes 31mm minimum thread length on the partially threaded rod. Mechanical properties comply with ISO 898-1 for Class 12.9 fasteners, while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe industrial use worldwide.
