Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 170,000 psi tensile strength for demanding industrial applications
- Precision thread engagement through Class 3A fit and UNC coarse threads ensuring vibration resistance
- Integrated flange design eliminates need for separate washers while distributing clamp load evenly
- Superior material durability from alloy steel with Rockwell C37 hardness resisting wear and deformation
- Optimized drive efficiency with external 12-point head allowing high-torque installation in confined spaces
- Full threading coverage along 1" length provides consistent grip strength across entire engagement area
- Regulatory compliance assurance meeting IFI 115 specifications and environmental standards (RoHS 3, REACH)
Professional Applications & Engineering Value
This 12-point flanged screw delivers critical performance advantages in heavy machinery, automotive assemblies, and structural frameworks where vibration resistance and high clamp force are paramount. The alloy steel construction maintains integrity under extreme stress cycles, while the UNC coarse thread profile prevents cross-threading during high-speed assembly. The integrated flange design streamlines installation by replacing washer components, reducing part count and potential failure points. Engineered for Class 3A thread fit, this fastener ensures zero-backlash connections in precision equipment, with the external 12-point drive accommodating standard industrial tools for consistent torque application.
Specification Summary & Compliance
Manufactured to IFI 115 specifications with Class 3A thread tolerance for precision fit. Features 7/16"-14 UNC coarse threads with right-hand orientation and full threading along 1" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensional accuracy maintained with 7/16" head dimensions and 21/32" flange diameter for consistent performance across production batches.
