Industrial-grade Grade 12.9 alloy steel DIN912 screws, covering M18-M27 metric sizes, feature a knurled cup head, full thread design, and hex socket drive. Engineered for high-strength fastening, these precision machine screws deliver exceptional tensile/shear resistance, reliable torque transfer, and durable performance, ideal for heavy machinery, industrial fixtures, and large-scale mechanical assemblies requiring robust load-bearing capacity.
Core Features & Advantages
Grade 12.9 High-Strength Alloy Steel: Premium alloy steel construction ensures superior tensile strength (1220MPa minimum) and shear resistance, withstanding high-stress industrial applications without deformation or failure, suitable for heavy-load scenarios.
DIN912 Standard Compliance: Strictly adheres to DIN912 specifications, guaranteeing uniform dimensions, precise full threads, and compatibility with standard hex socket tools, ensuring industrial interchangeability and quality consistency.
M18-M27 Size Range & Full Thread: Covers M18 to M27 metric sizes with full-thread design, maximizing thread engagement for stable fastening. Precisely machined threads ensure tight fit with metric nuts and components for versatile assembly needs.
Knurled Cup Head Design: Knurled cup head enhances grip during manual adjustment and prevents slippage, while the low-profile cup shape balances aesthetics and torque-bearing capacity, suitable for accessible and visible installations.
Hex Socket Drive Convenience: Hex (Allen) socket drive enables precise tightening in confined spaces, minimizing drive damage and facilitating efficient installation, maintenance, and disassembly for industrial workflows.
