S-92200A720 1/2"-13 x 2 1/2" MS16995-100, NAS1352C8-40, NASM16995, FF-S-86 Mil. Spec. 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
• High tensile strength of 80,000 PSI ensures reliable performance under significant load and stress in demanding applications.
• Secure and precise installation via the 3/8" hex drive, providing excellent torque transmission and reducing the risk of tool slippage.
• Optimized for specific assembly needs with a partially threaded design, allowing for unthreaded shank sections where clamping force is critical.
• Superior thread engagement and reliability with a Class 3A thread fit, ensuring tight tolerances and reduced risk of cross-threading.
• Enhanced durability and oxidation resistance from the passivated finish, prolonging the screw's lifespan even in corrosive conditions.
• Broad industrial compatibility with coarse (UNRC) thread spacing, facilitating quicker installation and disassembly.

Professional Applications & Engineering Value

This partially threaded socket head cap screw is engineered to address critical challenges in machinery assembly, automotive manufacturing, and heavy-duty equipment. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor or chemically exposed environments. The hex drive and socket head design allow for high-torque installation in confined spaces, reducing assembly time and improving fastener integrity. The partially threaded configuration ensures that the unthreaded shank bears shear loads effectively, while the threaded portion secures components without inducing unnecessary stress. With a coarse UNRC thread, it offers faster installation and robust holding power, ideal for applications requiring frequent maintenance or adjustments. This screw delivers reliable performance where high tensile strength and corrosion resistance are paramount, minimizing downtime and maintenance costs.
