Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 10-24 UNC hex head screws in 316 stainless steel deliver critical corrosion resistance where exposure to chemicals, saltwater, or extreme temperatures is a concern. The coarse thread design provides faster installation and superior vibration resistance compared to fine threads, making them ideal for machinery, equipment assembly, and structural applications. With fully threaded construction and Class 2A thread fit, they ensure maximum thread engagement and reliable clamping force, solving common issues of loosening under dynamic loads. The external hex drive accommodates high torque applications while the 70,000 PSI tensile strength maintains integrity in high-stress connections, offering engineers a durable fastening solution for critical assemblies.

Specification Summary & Compliance

This 10-24 UNC hex head screw features precise Class 2A thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy and interchangeability. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming restriction of hazardous substances. The 3/8" length and coarse thread spacing provide optimal performance in general-purpose industrial fastening applications where durability and corrosion resistance are paramount.
