• Secure and precise mounting with four 17/64" mounting holes arranged on a 1 1/8" bolt circle for reliable attachment.
• Optimized for high-strength assemblies featuring a robust 9/16"-18 UNF thread form for superior torque transmission and vibration resistance.
• Guaranteed material safety and compliance meeting RoHS 3 and REACH standards, making it suitable for global markets and sensitive applications.
• Robust flange profile with a 1 39/64" diameter and 13/32" thickness for enhanced load distribution and structural integrity.

Professional Applications & Engineering Value

This 303 Stainless Steel precision flange is engineered to solve critical challenges in motion control and power transmission systems. Its UNF 9/16"-18 thread provides a precise, fine-pitch connection that resists loosening under vibration, a common failure point in industrial machinery. The Brinell 140 hardness ensures the flange can withstand high clamping forces without deformation, maintaining alignment in precision Acme lead screw assemblies. The four-hole mounting pattern on a consistent bolt circle guarantees even pressure distribution, preventing warping and ensuring long-term reliability in demanding industrial applications such as CNC equipment, automated actuators, and heavy-duty positioning systems.
