Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 3/8"-16 UNC partially threaded pan head screws deliver exceptional performance where corrosion resistance and mechanical reliability are critical. The passivated 18-8 stainless steel construction provides superior protection against oxidation and chemical exposure, making them ideal for marine, chemical processing, and outdoor applications. The coarse UNC threading combined with partial threading design ensures rapid installation and superior holding power in softer materials or applications requiring vibration resistance. With their rounded pan head profile and Phillips No. 4 drive, these screws offer both aesthetic appeal and practical installation efficiency for machinery, equipment assembly, and structural fastening where consistent performance under load is essential.

Specification Summary & Compliance

These screws feature Class 2A thread fit tolerance ensuring precise engagement and reliable performance in UNC coarse thread applications. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance adherence. Thread configuration follows right-hand direction with 3/8"-16 UNC coarse spacing, providing optimal performance in standard industrial applications requiring 2 3/4" length fasteners with partial threading.
