Extended Product Information

FAQs

What does M6 x 20 mean?

M6 refers to the 6mm diameter of the thread, and 20 refers to the 20mm length of the threaded shank.

Can these be used outdoors?

While the BZP finish provides corrosion resistance, it is best suited for indoor or sheltered outdoor use. Prolonged exposure to moisture may cause rust over time.

Do I need a screwdriver to install these?

No, these are designed specifically for tool-free, hand-tightened installation.

What material is this fastener made of?

These are made from high-quality steel with a Bright Zinc Plated finish.

Can I use these for structural furniture frames?

No, these are intended for light-duty tasks, such as panel attachment or minor adjustments, not for structural load-bearing joints.

Troubleshooting

Screw is difficult to turn into the thread

Check for debris inside the target hole or ensure the alignment is perfectly perpendicular to the surface.

Screw loosens due to vibration

Consider using a small rubber O-ring or nylon washer between the screw head and the surface to provide tension and friction.

Pros and Cons

Pros

  • Easy to install and remove by hand without tools
  • Bright Zinc Plated finish prevents premature rust
  • Ideal for applications requiring frequent disassembly
  • Compact M6 size fits most common furniture assemblies

Cons

  • Not suitable for high-torque or heavy-load structural applications
  • Shoulderless design requires precise alignment for aesthetic flush-mounting
  • Requires manual dexterity to achieve a tight fit

Setup, Compatibility & Care

To ensure proper function, verify that the female thread (nut or insert) is a clean M6 size. If the screw feels resistant, do not force it to avoid damaging the thread pitch.

Care Instructions:

  • Wipe clean with a dry cloth to remove dust or debris from the knurled grip.
  • Keep in a dry, low-humidity environment to maintain the integrity of the BZP coating.
  • If threads become stuck, apply a small amount of light machine oil to the threads to facilitate smoother rotation.
