Professional Applications & Engineering Value

These cadmium-plated alloy steel socket head cap screws deliver critical performance advantages in precision engineering applications where space constraints and vibration resistance are paramount. The 2-56 thread size with UNRC coarse thread spacing provides optimal engagement in thin materials and blind holes, while the Class 3A thread fit maintains tight tolerances for vibration-prone environments. The hex drive socket head design enables high torque application without compromising the low-profile requirement in compact assemblies. These fully threaded screws are particularly valuable in aerospace, defense, and precision machinery where the combination of 160,000 PSI tensile strength and corrosion protection ensures long-term reliability in demanding operating conditions.

Specification Summary & Compliance

Manufactured to exacting inch system dimensions with Class 3A thread fit tolerances for precision assembly. The UNRC right-hand coarse thread configuration follows standardized threading practices. These socket head cap screws fully comply with MS16997-1 specifications and meet NAS1352-02-3P requirements for aerospace and defense applications. The cadmium plating provides corrosion resistance while maintaining electrical conductivity where required.
