FAQs

Are these bolts magnetic?

Most high-quality stainless steel bolts exhibit little to no magnetism, though some types may show slight attraction depending on the specific alloy grade.

What does the 0.7 signify in M4-0.7?

The 0.7 represents the thread pitch in millimeters, meaning the distance between two adjacent thread peaks.

Do I need a special tool to install these?

A standard Phillips head screwdriver of the correct size is all that is required for installation.

Can these be used for outdoor furniture?

Yes, their stainless steel construction makes them well-suited for outdoor use as they resist rust.

Are the nuts included in the package?

No, this package contains 100 bolts only; nuts are sold separately.

Troubleshooting

Screw head sits above the surface

The countersunk pilot hole is not deep enough; use a larger countersink bit to remove more material.

Bolt feels loose or stripped

Verify the thread pitch is M4-0.7; do not force if it does not spin easily.

Driver slips out of the Phillips head

Ensure you are using a #2 Phillips screwdriver; apply steady pressure and turn slowly to avoid 'cam-out'.

Pros and Cons

Pros

  • Flush finish improves aesthetics and safety
  • High-grade stainless steel prevents rusting
  • Standardized M4 threading ensures wide compatibility
  • Bulk pack provides excellent value for frequent users

Cons

  • Specific 8mm length limits use in thicker material
  • Phillips head can strip if incorrect driver size is used
  • Not intended for high-torque structural steel frames

Setup, Compatibility & Care

To ensure a professional installation, always pre-drill or use a countersink bit to create a beveled hole that matches the bolt head angle. This prevents the wood or plastic from splitting and ensures the head sits perfectly level.

Compatibility: These bolts fit any M4-0.7 threaded insert or nut. Do not attempt to force these into non-metric threads.

Care: While stainless steel is rust-resistant, avoid using high-acidity cleaners near the hardware. If installing in marine or saltwater environments, applying a small amount of anti-seize lubricant can prevent potential galling of the threads.
