S-91355A175 10-32 x 2" Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance thanks to the black-oxide coating on alloy steel, extending service life in harsh industrial environments
• Superior thread engagement and vibration resistance achieved with precision-machined 10-32 UNF Class 3A fine threads for secure, reliable fastening
• High-torque installation capability enabled by the 1/8" hex drive and wide button head design, preventing cam-out and simplifying assembly
• Enhanced load distribution and surface protection from the integrated flange, reducing the risk of material damage under high clamping forces
• Optimal strength-to-weight ratio with a 120,000 psi tensile strength and Rockwell C32 hardness, ensuring durability under heavy mechanical stress
• Full-threaded design for maximum grip length, providing consistent holding power along the entire 2" length for deep or variable material thicknesses
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and international supply chains

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 10-32 UNF Class 3A threaded screws address critical challenges in machinery assembly, automotive components, and heavy equipment. The black-oxide alloy steel construction provides excellent resistance to corrosion and wear, while the fine UNF threads and Class 3A fit ensure precise alignment and superior vibration resistance in high-stress environments. The combination of a flanged, wide button head and 1/8" hex drive allows for efficient installation with standard tools, reducing assembly time and minimizing the risk of head stripping. With a fully threaded design and 120,000 psi tensile strength, these screws deliver reliable performance in applications requiring consistent clamping force and durability, from electronic enclosures to structural frameworks.
