S-92210A010 0-80 x 1/8" ASME B18.3 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel and passivated finish, ideal for harsh environments and extended service life.
• High-strength performance delivering 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing in demanding applications.
• Precise thread engagement with Class 3A fit and UNF fine threads, ensuring secure fastening and vibration resistance.
• Efficient installation and removal via the hex drive design, providing positive torque transmission and reducing tool slippage.
• Flush mounting capability with the standard 82° flat head profile, allowing for a smooth surface finish in countersunk holes.
• Full threading along the 1/8" length maximizes grip and distribution of clamping force across the entire fastener.
• Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring quality and environmental safety.

Professional Applications & Engineering Value

This 0-80 UNF flat head screw is engineered to address critical needs in precision assemblies where space is constrained and reliability is non-negotiable. Manufactured from 18-8 Stainless Steel and featuring a passivated finish, it resists oxidation and chemical exposure, making it suitable for electronics, aerospace, medical devices, and marine applications. The fine UNF threads and Class 3A thread fit provide superior holding power in thin materials, reducing the risk of stripping. The hex drive ensures high torque application without cam-out, while the 82° countersink angle allows the head to sit flush, preventing snagging and improving aesthetics. Its fully threaded design ensures consistent clamping in shallow depths, solving alignment and vibration-loosening challenges in compact machinery and instrumentation.

Specification Summary & Compliance

This screw adheres to Class 3A thread fit tolerances per UNF standards, ensuring precise thread engagement. It meets ASME B18.3 specifications for dimensional consistency and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming it is free from hazardous substances and safe for use in regulated markets.
