S-94414A247 10-24 x 1" ASME B18.3, ASTM F835 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional torque transmission with Torx Plus IP25 drive system, reducing cam-out and tool wear during high-torque applications
• Superior corrosion resistance through black-oxide coating on alloy steel, extending service life in demanding industrial environments
• Maximum thread engagement with Class 3A thread fit and UNC coarse threading, ensuring secure fastening in various materials
• Enhanced structural integrity from 140,000 psi tensile strength and Rockwell C39 hardness, preventing failure under heavy loads
• Flush mounting capability with standard 82° countersink angle flat head design, creating smooth surfaces in assembled components
• Full-length threading providing consistent holding power along the entire 1" screw length for uniform load distribution
• Regulatory compliance assurance meeting ASME B18.3, ASTM F835, RoHS 3, and REACH standards for global industrial applications

Professional Applications & Engineering Value

These 10-24 UNC flat head screws deliver critical engineering solutions where vibration resistance and high-strength fastening are paramount. The black-oxide alloy steel construction combined with Torx Plus IP25 drive addresses common industrial challenges of fastener stripping and corrosion-induced failure. In machinery assembly, automotive manufacturing, and heavy equipment applications, the Class 3A thread fit ensures precise engagement while the 82° countersink angle provides seamless integration into components requiring flush surfaces. The 140,000 psi tensile strength makes these fully threaded screws ideal for structural connections subject to dynamic loads and thermal cycling, significantly reducing maintenance intervals and replacement costs in demanding operational environments.

Specification Summary & Compliance

Manufactured to exacting Class 3A thread standards with UNC coarse threading (10-24 size) and precise dimensional tolerances per ASME B18.3 specifications. These flat head screws comply with ASTM F835 manufacturing standards and feature full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment provides consistent corrosion protection while maintaining the 140,000 psi tensile strength and Rockwell C39 hardness of the underlying alloy steel material.
