S-96242A588 1/4"-28 x 1 3/4" 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 450 Stainless Steel construction, ideal for harsh industrial environments
• Superior torque transmission and reduced tool slippage thanks to the external 12-point drive and 5/16" drive size
• High load-bearing capacity with a 170,000 psi tensile strength and Rockwell C37 hardness for demanding applications
• Precise, secure fastening ensured by the Class 3A thread fit and UNF fine threading, minimizing loosening under vibration
• Enhanced stability and load distribution from the integrated flange, eliminating the need for separate washers
• Optimized for partial threading providing unthreaded shank strength where needed, improving shear resistance
• Reliable right-hand thread direction for standard assembly processes, ensuring compatibility and ease of use

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this 12-point screw addresses critical challenges in machinery, automotive, and construction sectors where vibration resistance and high tensile loads are paramount. The 450 Stainless Steel material offers excellent durability against corrosion and wear, while the UNF fine threading and Class 3A fit provide superior clamping force and precision alignment, reducing the risk of joint failure. The external 12-point drive allows for high-torque installation with common tools, enhancing efficiency in assembly lines. Its flanged design distributes pressure evenly, protecting sensitive surfaces and simplifying installation in tight spaces, making it a reliable choice for high-stress fastening scenarios.

Specification Summary & Compliance

This screw adheres to UNF thread standards with a Class 3A thread fit for precise dimensional accuracy and minimal tolerance. It meets industry specifications for inch system measurements, including a thread size of 1/4"-28 and partial threading over a 1 3/4" length. Manufactured from 450 Stainless Steel, it complies with common industrial requirements for strength and corrosion resistance, though specific certifications like RoHS or REACH should be verified per batch. The design ensures compatibility with standard external 12-point drive tools, supporting efficient, reliable fastening in regulated environments.
