Key Features & Benefits at a Glance
- Superior torque transfer with T20 Torx drive, reducing cam-out and tool wear for efficient assembly
- Enhanced corrosion resistance through zinc plating, extending service life in harsh industrial environments
- High tensile strength of 60,000 PSI ensures reliable load-bearing capacity and joint integrity
- Precise flush mounting with 82° countersink angle and standard flat head profile for seamless surface finishes
- Optimized thread engagement using coarse UNC threads with Class 2A fit for quick installation and vibration resistance
- Full 3/4" threading provides maximum grip length and uniform stress distribution in assemblies
- Regulatory compliance with ASME B18.6.3, RoHS 3, and REACH ensures safety and environmental responsibility
Professional Applications & Engineering Value
These 10-24 UNC flat head Torx screws are engineered to address critical challenges in industrial assembly where space constraints and high-stress conditions prevail. The zinc-plated steel construction combats corrosion in manufacturing facilities, while the T20 Torx drive prevents stripping under high torque applications like machinery frames and automotive components. With coarse threads and Class 2A fit, they maintain secure fastening in vibrating environments, and the 82° countersink allows flush installation in sheet metal and precision equipment. Ideal for right-hand threaded applications requiring 60,000 PSI tensile strength, these screws deliver consistent performance in fully threaded configurations for robust mechanical joints.
Specification Summary & Compliance
This product adheres to Class 2A thread fit tolerances per UNC standards, ensuring dimensional accuracy for inch-based systems. Manufacturing follows ASME B18.6.3 specifications for flat head machine screws, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The coarse thread spacing and fully threaded design meet industrial requirements for durability and ease of use.
