Overview
These socket head cap screws are engineered specifically for demanding industrial
applications
where traditional metal fasteners are unsuitable. Constructed entirely from high-grade polyurethane, they offer exceptional corrosion resistance and superior electrical insulation properties. The design
features
a standard 1/4-20 thread size combined with a 1.5-inch length to ensure secure fastening in non-conductive assemblies. Finished in a matte black color to minimize visual distraction, these fasteners utilize a hex drive system for efficient installation using common tooling. They are an ideal solution for environments requiring chemical stability, reduced weight, and dielectric strength without compromising structural integrity.
Key Features
Superior corrosion resistance against harsh chemicals and solvents Complete electrical insulation for safe use in live or sensitive electronic environments Lightweight polyurethane construction reduces overall assembly mass Black finish provides low visibility and aesthetic consistency Hex drive interface allows for high torque application during installation Non-magnetic properties ideal for MRI suites and magnetic sensing equipment Resistant to UV degradation and weathering for indoor and outdoor use

Applications
Chemical processing equipment and piping systems Electrical enclosures and circuit board mounting Food and beverage processing machinery requiring non-metallic contact Marine environments prone to saltwater corrosion Medical imaging rooms where non-magnetic hardware is mandatory Water treatment facilities and pump assemblies Laboratory fixtures exposed to acidic or caustic solutions Automotive testing rigs requiring dielectric isolation Performance Notes The polyurethane
material
maintains its mechanical properties across a wide temperature range, ensuring reliable clamping force in fluctuating thermal conditions. Unlike metal alternatives, these screws will not gall or seize when installed into threaded plastic or composite inserts. The 1/4-20 thread pitch offers a balanced combination of holding power and ease of assembly, making it suitable for both permanent and serviceable connections. Users should
note
that while the tensile strength is sufficient for most non-structural applications, torque values must be adjusted compared to steel equivalents to prevent stripping of the internal hex drive or the external threads. Regular inspection is recommended in high-vibration settings to ensure continued joint integrity.
