SystemShield 1/4"-20 Hex Nut

1/4"-20 Hex Nut

Short Description

Steel 1/4"-20 hex nut for machine-thread fastening in grounding, bonding, cabinet, enclosure, and equipment assemblies. Matching listings show zinc-plated steel, ASME B18.2.2 dimensional standard, 7/16 in width across flats, and 7/32 in nominal height for this size class.

Product Overview

The SystemShield 1/4"-20 Hex Nut is a machine-thread fastening component intended for use with compatible bolts, screws, washers, and bracketed assemblies where a standard hex nut is required. Matching commercial listings identify this configuration as 1/4 in diameter, 20 TPI coarse thread, and right-hand thread in a standard hex-nut format.

For this size class, matching dimensional references show a 7/16 in width across flats with a tolerance range of about 0.428 to 0.438 in, and a 7/32 in height with a tolerance range of about 0.212 to 0.226 in. Matching listings also show zinc-plated steel construction and ASME B18.2.2 dimensional standard references for this common finished hex nut format.

This nut format is well suited for cabinet hardware, enclosure assembly, bracket mounting, and bonded mechanical joints where a 1/4"-20 machine-thread connection is required with separate washer and bolt hardware.

Key Features

• 1/4"-20 coarse machine thread format
• Standard hex nut geometry for wrench-driven fastening
• Steel construction for general mechanical fastening use
• Zinc-plated finish for moderate corrosion resistance
• ASME B18.2.2 dimensional standard reference
• 7/16 in width across flats for this size class
• 7/32 in nut height for this size class
• Suitable for use with compatible 1/4"-20 bolts, washers, and mounting hardware

Technical Specifications

What’s Included

• (1) 1/4"-20 hex nut
• No bolt included
• No washer included
• No locking element included

Typical Applications

• Bracket mounting assemblies
• Cabinet hardware fastening
• Enclosure assembly fastening
• Bonding hardware stack-ups using separate bolt and washer hardware
• General machine-thread fastening where 1/4"-20 hardware is specified
• Equipment mounting points requiring standard hex hardware

Compatibility

Compatible with:

• 1/4"-20 hex head bolts, machine screws, and mating threaded hardware systems sized for this thread
• 7/16 in wrench or socket tools sized for this nut format
• Compatible flat washers and lock washers sized for 1/4 in hardware
• 1/4"-20 × 1 in Hex Head Bolt
• SystemShield Standard Mounting Hardware Kit, where this nut is a primary included hardware component

Not intended as:

• A self-locking nut unless separately specified
• A substitute for a different thread system or nut style where exact match is required
• A standalone fastener without correct mating hardware

Installation Notes

1. Use this nut only with assembly points designed for 1/4"-20 machine threads. Confirm that the mating bolt or screw, washer stack, and joint design match the thread size, pitch, and required engagement before installation.
2. Install with a properly fitting 7/16 in wrench or socket.
3. Because zinc-plated steel hex nuts 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, height and clearance suitability, washer requirements, bolt length compatibility, and application requirements before installation.

Compliance & Regulatory Information

Matching listings support this nut format as a steel, zinc-plated, ASME B18.2.2 machine-thread fastener. 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 corner deformation
• Protect against plating damage
• Protect against corrosion from improper storage conditions

Store in a clean, dry environment before installation. Do not use damaged nuts with deformed threads or distorted wrench flats.

Notes / Limitations

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

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