S-99477A150 6-32 x 1" Plastic Socket Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant polypropylene construction ensures reliable performance in humid or chemical environments without rust or degradation.
• Precise Class 2A thread fit guarantees smooth installation and secure fastening with standard UNC coarse threaded components.
• Hex socket drive (7/64") allows for high-torque application and easy access in confined spaces with common Allen keys.
• Wide temperature tolerance (-20° to 210°F) maintains structural integrity across diverse operating conditions.
• Full threading along 1" length provides maximum adjustability and holding power in assemblies.
• RoHS 3 & REACH compliance meets stringent international regulations for safe use in industrial and consumer products.
• Lightweight off-white design offers aesthetic consistency and reduces overall assembly weight versus metal alternatives.

Professional Applications & Engineering Value

Engineered for precision assembly applications, these polypropylene socket head cap screws deliver exceptional chemical resistance and electrical insulation properties where metal fasteners would corrode or cause galvanic reactions. The 6-32 UNC coarse thread with Class 2A fit ensures rapid installation in plastic housings, electronic enclosures, and machinery components while resisting vibration loosening. With a hex drive compatibility and fully threaded 1" length, they provide uniform clamping force in automated production lines, laboratory equipment, and food-safe assemblies where temperature fluctuations from -20° to 210°F are common. The off-white color blends discreetly in consumer products and medical devices while maintaining RoHS 3 and REACH compliance for global market access.

Specification Summary & Compliance
