Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 450 Stainless Steel construction, ideal for harsh industrial environments.
- Superior load-bearing capability from a high 170,000 psi tensile strength, ensuring joint integrity under extreme stress.
- Precise, reliable fastening due to Class 3A thread fit, minimizing the risk of cross-threading and ensuring consistent clamp load.
- Enhanced torque transmission and reduced slipping with the external 12-point drive and 5/16" drive size, suitable for high-torque applications.
- Increased stability and distributed load thanks to the integrated flange, eliminating the need for a separate washer.
- Optimized for fine-thread applications with UNF 1/4"-28 threading, providing superior resistance to vibration loosening.
- Versatile partial threading design allows for precise grip length control, ideal for materials where full threading is not required.
Professional Applications & Engineering Value
Engineered for demanding scenarios, this 12-point flanged screw in 450 Stainless Steel addresses critical challenges in assembly and maintenance. Its Class 3A UNF fine thread ensures a tight, secure fit in high-vibration machinery, preventing operational failures. The external 12-point drive facilitates efficient installation in confined spaces, reducing assembly time. The flange design distributes clamping force evenly, protecting soft materials and enhancing joint durability. With a Rockwell C37 hardness and 170,000 psi tensile strength, it is a reliable choice for heavy-duty industrial equipment, automotive systems, and structural applications where precision and reliability are non-negotiable.
Specification Summary & Compliance
This screw adheres to UNF (Unified National Fine) thread standards with a Class 3A fit for high precision. It is partially threaded with a minimum thread length of 1" and a total length of 1 1/4". Manufactured from 450 Stainless Steel, it meets industry requirements for corrosion resistance and mechanical properties. Compliant with RoHS and REACH regulations, ensuring environmental and safety standards are upheld.
