Electro Hardware HHCS-14-1250-N Hex Head Cap Screw 100pk

Product Description

The ELECTRO HARDWARE HHCS-14-1250-N is a 1/4-20 hex head cap screw manufactured from Grade 6/6 Nylon, designed for applications where metal fasteners are unsuitable due to corrosion, electrical conductivity, or chemical exposure concerns. The screw measures 1-1/4 inches under the head with a Unified National Coarse (UNC) thread form and is partially threaded. It carries an uncoated finish and conforms to ASTM D789-66 Type 1 GDE2 standards. Each package contains 100 pieces. This fastener is installed by maintenance technicians, electricians, plumbers, and mechanical contractors working in environments where non-metallic hardware is required.

This hex head cap screw is suited for light-duty panel assembly, electrical enclosure work, plumbing fixture mounting, and general mechanical assembly where non-conductive or corrosion-resistant fasteners are specified. The 1/4-20 UNC thread size is one of the most common inch-series thread standards, making this screw broadly applicable across residential, commercial, and light industrial service work. The partial threading is appropriate for through-bolt applications where thread engagement is needed only at the fastened joint.

Key Features

• Grade 6/6 Nylon construction resists corrosion, moisture, and electrical conductivity
• 1/4-20 UNC thread form — one of the most widely used inch-series coarse thread standards
• 1-1/4 inch length under head with partial threading for through-bolt fitment
• Uncoated finish — no risk of coating degradation in chemical or wet environments
• Conforms to ASTM D789-66 Type 1 GDE2 nylon material standard
• Sold in a 100-piece package to support service inventory and job-lot quantities

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw for use in any application specifying inch-series, Grade 6/6 Nylon, partially threaded fasteners conforming to ASTM D789-66 Type 1 GDE2.

Installation Notes

Install using a standard hex driver or wrench sized for a 1/4-inch hex head cap screw. Nylon fasteners have lower tensile and torque ratings than steel equivalents — do not exceed manufacturer-specified clamp loads for nylon hardware. Avoid installation in high-temperature environments where nylon may soften or creep. No special certifications are required for fastener installation, but follow applicable mechanical and electrical codes for the specific application.
