Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw delivers critical sealing performance where standard fasteners fail. The 18-8 stainless steel construction provides excellent corrosion resistance for marine, chemical processing, and outdoor equipment applications. The integrated silicone rubber O-ring creates a permanent seal against fluids and gases, solving leakage issues in hydraulic systems, pressure vessels, and pneumatic equipment. The coarse thread design ensures rapid assembly in production environments while the fully threaded configuration maximizes grip length. With 80,000 PSI tensile strength, this external hex drive screw maintains structural integrity under extreme mechanical loads, making it ideal for heavy machinery, industrial pumps, and high-pressure piping systems where reliability is paramount.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse threading (3/8"-16). The screw features a 9/16" hex head width and 3/4" length with fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The O-ring material meets -80° to 400°F temperature range specifications while maintaining sealing capability up to 20,000 PSI maximum pressure.
