- Partial threading offers optimal grip length control for precise clamping applications
Professional Applications & Engineering Value
These 3/8"-16 UNC hex head screws deliver exceptional performance in demanding industrial settings where corrosion resistance and mechanical strength are critical. The 18-8 stainless steel composition combined with ASTM A193 Grade B8 certification ensures reliable operation in chemical processing, marine applications, and high-temperature environments. The coarse thread design provides superior vibration resistance compared to fine threads, while the external hex drive enables high-torque installation without stripping. With 75,000 PSI tensile strength and controlled partial threading, these fasteners maintain clamping force integrity in pressure vessels, piping systems, and structural assemblies where precise grip length is essential for safety and performance.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances for consistent engagement and proper clearance. Complies with ASTM A193 specification for high-temperature service alloy steel bolting materials. The UNC coarse thread (3/8"-16) follows standardized inch system measurements with 0.375" diameter and 1.5" total length. Meets industry standards for chemical composition, mechanical properties, and dimensional requirements suitable for critical industrial applications.
