M3 10mm Screw - Bolt with Nut Combo (5+5)

The M3 10mm Stainless Steel Screw and Nut Combo is a standard metric fastening solution widely used in robotics, electronics mounting, mechanical assemblies, and lab fixtures. Designed with a 3 mm thread diameter and 10 mm length, this fastener set is optimized for compact and lightweight structures.

The pack includes:

• 5 x M3 10mm hex socket screws  

• 5 x M3 matching hex nuts  

Made from 304 stainless steel, the set provides corrosion resistance, strength, and long service life.

Q: Is this combo suitable for robotics chassis work?  

Yes. The 10 mm length is ideal for thin plates and layered structures.

## Technical Architecture

The screw follows ISO metric M3 thread standards with right-hand threading. The nut is manufactured to match standard M3 pitch, ensuring smooth engagement and secure clamping.

The hex socket head enables internal drive tightening using a 2 mm Allen key, which is preferred for compact assemblies where external spanners may not fit.

Problem-Solution:

Problem: Mismatch between screws and nuts purchased separately  

Solution: This combo ensures compatible screw and nut pairing

## Why Choose This Combo?

• Ready-to-use matched hardware set  

• Stainless steel corrosion resistance  

• Ideal short length for compact assemblies  

• Reusable for repeated assembly/disassembly  

• Suitable for institutional kits

Compared to buying loose hardware, this combo reduces compatibility issues and simplifies inventory management.

## Comparison with Related Variants

• M3 20mm or 30mm screws – for thicker assemblies  

• Mild steel hardware – lower cost but prone to rust  

• Longer bolt sets – for multi-layer frames  

The 10 mm version is best for:

• PCB mounting  

• Thin acrylic sheets  

• Enclosures  

• Lightweight robotics frames  

## Pin & Interface Overview

Not applicable. This is a mechanical fastening product.

## Power System Explanation

Not applicable. No electrical connection or power requirement.

## Common Issues & Troubleshooting

Issue: Nut not tightening smoothly  

Cause: Cross-threading  

Solution: Start threading manually before tightening

Issue: Hex socket stripping  

Cause: Wrong hex key size  

Solution: Use 2 mm hex key only

Issue: Loosening in vibration environments  

Solution: Use washer or thread locker if required
