Stewart Fastener J2516MRCZ 1/4-20 X 1 Round Head Machine Screws

Product Description

The STEWART FASTENER J2516MRCZ is a 1/4-20 x 1 inch round head combination drive machine screw with a zinc finish, sold in a jar of 100. These screws feature a round head profile and a combination drive that accepts both slotted and Phillips drivers, making them practical for general fastening work across a range of trade and industrial applications. The zinc coating provides basic corrosion resistance for use in dry and mildly humid environments. Each jar contains 100 screws, packaged for convenient bench or field use.

These machine screws are suited for light mechanical assemblies, electrical panel work, HVAC equipment enclosures, and general metalwork where a 1/4-20 thread is specified. The combination drive head is compatible with standard hand tools and power drivers. They are commonly used by electricians, HVAC technicians, and maintenance professionals who need a reliable fastener stocked in volume quantities for repetitive applications.

Key Features

• 1/4-20 thread size with 1 inch length for standard mechanical fastening applications
• Round head profile provides a low-profile bearing surface and clean finished appearance
• Combination drive accepts both slotted and Phillips drivers for flexible tool use
• Zinc finish offers basic corrosion resistance in dry to mildly humid conditions
• Sold in a jar of 100 for high-volume or repetitive fastening tasks

Compatibility

Designed as a standard 1/4-20 machine screw for use in any application requiring that thread size and a round head profile, including electrical enclosures, equipment panels, and light mechanical assemblies.

Installation Notes

Installation requires a properly tapped or pre-threaded hole sized for 1/4-20 threads. Use the appropriate slotted or Phillips driver to avoid cam-out and head damage. Always follow applicable codes and equipment manufacturer guidelines when fastening electrical or mechanical enclosures. Do not overtighten, as this can strip threads in softer base materials.
