Key Features & Benefits at a Glance
- Corrosion-resistant polypropylene construction ensures reliable performance in chemical and moisture-rich environments without rust or degradation
- Precise Class 2A thread fit guarantees smooth installation and secure fastening with standard UNC mating components
- Wide temperature tolerance (-20° to 210°F) maintains structural integrity across industrial and outdoor applications
- 3/16" hex socket drive provides superior torque transmission and prevents tool slippage during high-tension assembly
- Full RoHS 3 & REACH compliance eliminates hazardous substances for safer workplace handling and environmental protection
- Coarse UNC threading enables rapid installation and reduced cross-threading risks in production environments
- 2" fully threaded design offers maximum adjustment flexibility and uniform load distribution
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these polypropylene socket head cap screws solve critical challenges in electrical enclosures, food processing equipment, and chemical handling systems where metal fasteners would corrode or contaminate processes. The off-white color provides visual contrast for quality control inspections, while the coarse 1/4-20 UNC threads maintain holding power in vibration-prone assemblies. The hex socket drive allows flush mounting in confined spaces where external wrench clearance is limited, making these plastic fasteners ideal for maintenance-free applications requiring temperature resistance and regulatory compliance.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with UNC coarse threading standards, ensuring compatibility with industry-standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance adherence. The 0.25" thread diameter and 3/8" head diameter maintain dimensional consistency across production batches for reliable assembly performance.
