SystemShield 12-24 × 1" Phillips Pan Head Machine Screw

12-24 × 1 in Phillips Pan Head Machine Screw

Short Description

Steel 12-24 × 1 in Phillips pan head machine screw for mounting and fastening applications in grounding, bonding, enclosure, cabinet, and equipment assemblies. Matching listings and dimensional references show ASME B18.6.3 machine-screw geometry, 0.216 in major diameter, 24 TPI coarse thread, #3 Phillips drive, and zinc-plated steel construction for general-use corrosion resistance.

Product Overview

The SystemShield 12-24 × 1 in Phillips Pan Head Machine Screw is a machine-thread fastener intended for use in tapped holes, threaded inserts, nuts, cage-nut systems, and similar machine-fastened assemblies. This screw format is commonly used where a rounded low-profile head, Phillips drive access, and machine-thread engagement are required.

Matching product listings identify this configuration as a #12 diameter, 24 TPI, 1 in long, right-hand, coarse-thread machine screw.

For the size class relevant here, matching listings show steel base material with zinc plating for moderate corrosion resistance in general indoor or protected-use assemblies. Head geometry for this size is shown at about 0.407 to 0.425 in head diameter and about 0.139 to 0.151 in head height, with a #3 Phillips drive.

This screw is well suited for cabinet hardware, enclosure mounting, equipment bracket fastening, and similar assembly points where machine-thread fastening is required and the joint design calls for a 12-24 screw format.

Key Features

• Grounding, bonding, cabinet, and enclosure assemblies requiring this thread and length format

Not intended as:

• A self-tapping sheet-metal screw
• A wood screw
• A substitute for a different thread system, drive system, or length where exact hardware match is required

Installation Notes

1. Use this screw only in assembly points designed for 12-24 machine threads. Confirm that the receiving nut, cage nut, threaded hole, or insert matches the thread size, thread pitch, and required engagement length before installation.
2. Install with a properly fitting #3 Phillips driver to reduce drive damage and cam-out risk.
3. Because zinc-plated steel machine screws are general-use fasteners, final torque and joint suitability should be determined by the actual mating materials, hardware stack-up, and application requirements.
4. Verify thread match, length suitability, head clearance, washer or nut requirements, and application requirements before installation.

Compliance & Regulatory Information

Matching listings support this screw format as a steel, zinc-plated, ASME B18.6.3 machine screw configuration. The sources reviewed establish dimensional and material details, but they do not show a separate standalone certification claim that should be carried into this listing as a broader compliance statement.

It should be used only as part of a properly designed assembly and with hardware selected for the actual joint and environment.

Packaging & Handling

• Protect against thread damage
• Protect against drive recess damage
• Protect against plating damage
• Protect against corrosion from improper storage conditions

Store in a clean, dry environment before installation. Do not use damaged screws with deformed threads or stripped drive recesses.

Notes / Limitations

This product is a fastening component, not a complete assembly.

• Final suitability depends on correct thread match
• Correct length selection is required
• Correct mating hardware is required
• Proper installation practices are required
• Actual application requirements must be verified
