Professional Applications & Engineering Value
Engineered for precision assembly where electrical insulation and chemical resistance are critical, these socket head cap screws solve common metal fastener limitations in electronics enclosures, laboratory equipment, and food processing machinery. The Polypropylene material eliminates galvanic corrosion when mating with dissimilar metals while maintaining dimensional stability across the -20° to 210° F temperature range. The 6-32 UNC coarse thread configuration ensures rapid installation in plastic and soft material applications, reducing assembly time and improving production throughput. With Class 2A thread fit tolerances, these fasteners deliver consistent clamping force without compromising thread integrity.
Specification Summary & Compliance
Manufactured to UNC thread standards with Class 2A fit tolerances for consistent thread engagement. The 0.138" thread diameter and coarse thread spacing adhere to standardized inch system specifications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances. The fully threaded design maintains uniform mechanical properties along the entire 3/4" length for reliable performance in industrial applications.
