S-95841A806 5/8"-11 x 3" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance due to PVC plastic construction, ideal for humid or chemical environments
• Easy installation and removal with standard 7/8" external hex head design for common wrench tools
• Reliable coarse threading (UNC) provides superior holding power in plastic and soft materials
• Precision Class 2A thread fit ensures consistent engagement and reduces cross-threading risks
• RoHS 3 compliance meets environmental regulations for electronics and sensitive applications
• Temperature resistance up to 140°F maintains integrity in moderate heat conditions
• Partially threaded shank design allows for controlled clamping force and material stress distribution

Professional Applications & Engineering Value

These PVC plastic hex head screws deliver exceptional value in applications where metal fasteners would corrode or cause galvanic reactions. The 5/8"-11 UNC coarse thread configuration provides optimal pull-out resistance in plastic assemblies, electrical enclosures, and chemical processing equipment. The gray PVC material offers inherent UV stability and electrical insulation properties, making these screws ideal for outdoor installations and electronic housing applications. With Class 2A thread fit precision, engineers can achieve consistent torque values and reliable joint integrity without the risk of material stripping common in plastic-to-plastic fastening scenarios.

Specification Summary & Compliance

This 3" long hex head screw features a 5/8"-11 UNC coarse thread with Class 2A thread fit tolerance per ASME B1.1 standards. The partially threaded design provides 1½" of engaged threading with 0.625" major diameter. Manufactured from industrial-grade PVC plastic with external hex drive (7/8" across flats, 31/64" height). Compliant with RoHS 3 (2015/863/EU) environmental regulations and rated for continuous service up to 140°F operating temperature.
