- Full thread engagement along the 1/2" length, providing consistent clamping force and vibration resistance
Professional Applications & Engineering Value
These 6-32 UNC flat head screws with integrated Buna-N rubber O-ring address critical sealing challenges in industrial equipment, fluid systems, and pressurized enclosures. The 316 stainless steel material offers exceptional resistance to chlorides and corrosive agents, while the undercut flat head design ensures a flush surface finish and maximizes O-ring compression for leak-proof performance. Engineered for high-pressure applications up to 1500 psi, these fully threaded screws provide uniform stress distribution and reliable sealing in hydraulic systems, pneumatic controls, and outdoor machinery exposed to temperature fluctuations from -40° to 225° F. The coarse thread and Phillips drive facilitate quick installation in tight spaces, reducing assembly errors and maintenance downtime.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (6-32 size) and 82° countersink angle. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. Designed for maximum hole diameter of 0.152" with fully threaded 1/2" length.
