Professional Applications & Engineering Value
These 10-24 UNC A286 stainless steel Torx button head screws deliver critical performance advantages in demanding industrial environments. The A286 stainless steel composition provides exceptional resistance to oxidation and corrosion, making these rounded head screws ideal for aerospace, automotive, and marine applications where environmental factors compromise fastener integrity. The T25 Torx drive system ensures superior torque transmission, eliminating the stripping issues common with Phillips and slotted drives while the Class 2A thread fit guarantees consistent engagement without binding. With 130,000 psi tensile strength and Rockwell C24 hardness, these fully threaded fasteners maintain clamping force under extreme vibration and thermal cycling, solving critical failure points in high-stress assemblies.
Specification Summary & Compliance
This 10-24 UNC screw features precise Class 2A thread fit tolerances with coarse thread spacing and right-hand thread direction. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental responsibility and regulatory acceptance for industrial applications worldwide. Manufacturing specifications include fully threaded design with 0.19" thread diameter and standardized rounded button head profile for consistent performance across assembly operations.
