S-90271A249 10-24 x 1 1/4" ASME B18.6.3 Steel Truss Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced load distribution through wide truss head design (0.448" diameter) that reduces surface pressure and prevents material damage
• High mechanical strength with 60,000 psi tensile strength and Rockwell B69 hardness for reliable performance under stress
• Quick installation and removal with coarse UNC threading and Class 2A fit ensuring smooth engagement in various materials
• Full-threaded design provides maximum grip length and consistent clamping force across the entire fastener length
• Comprehensive compliance with ASME B18.6.3 manufacturing standards and environmental regulations including RoHS 3 and REACH
• Versatile slotted drive accommodates standard tools for easy installation in space-constrained applications

Professional Applications & Engineering Value

These 10-24 UNC coarse thread screws with zinc-plated steel construction address critical industrial fastening challenges where corrosion resistance and structural integrity are paramount. The rounded truss head profile distributes clamping force over a wider surface area, preventing damage to softer materials while maintaining secure fastening. The fully threaded right-hand design ensures maximum thread engagement in metal assemblies, electrical enclosures, and machinery components. With 60,000 psi tensile strength and Rockwell B69 hardness, these industrial screws withstand vibration and dynamic loads in manufacturing equipment, automotive applications, and construction projects. The coarse threading provides excellent holding power in both metallic and non-metallic substrates, making them ideal for production lines requiring rapid assembly and disassembly.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with UNC coarse thread specification (10-24 size). Complies with ASME B18.6.3 dimensional and mechanical requirements. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions. Features 1-1/4" length with fully threaded design and 0.19" thread diameter for consistent performance across industrial applications.
