Professional Applications & Engineering Value
These 8-32 UNC flat head screws with integrated Buna-N rubber O-rings provide critical sealing solutions for industrial equipment exposed to fluids, gases, and environmental contaminants. The 316 stainless steel construction delivers outstanding corrosion resistance in chemical processing, marine, and food industry applications where moisture and aggressive media are present. The undercut flat head profile ensures proper seating while the Phillips drive facilitates efficient installation. Engineered to maintain integrity across a broad temperature range from -40° to 225°F, these sealing screws prevent leakage in hydraulic systems, pneumatic controls, and fluid handling equipment where pressure containment up to 1500 psi is essential for operational safety and reliability.
Specification Summary & Compliance
This fastener features 8-32 UNC coarse threads with Class 2A thread fit for consistent engagement, measuring 0.164" thread diameter and 3/8" length with full threading. The flat head design incorporates an 82° countersink angle and undercut profile for optimal seating. Manufactured to precise dimensional standards with maximum hole diameter of 0.179". Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications worldwide.
