SIGMA

SIGMA 4.5 mm M3X6 Hex Key Screws, 4-Pack

SKU CH-ZERJ-2Z7R2

Four 4.5 mm M3×6 stainless-steel hex-key screws for securing support-rig accessories

  • Precise 4.5 mm diameter ensures secure rig connections
  • Stainless steel construction delivers long-lasting durability
  • Lightweight design maintains optimal balance during shoots
  • Compatible with multiple Sigma support accessories
  • Four-pack provides ready spares for field use

Essential fastening hardware for video rigs

These Sigma M3X6 hex key screws come in a four-pack and are made from robust stainless steel. Each screw measures 4.5 mm in diameter and 6 mm in length. They are designed to secure support rig accessories such as video stabilizers and supports with a precise, wobble-free fit.

Limited to M3 thread pattern and 6 mm depth

The M3X6 specification restricts use to equipment tapped for that exact thread size and length. Builders needing a different thread pitch, diameter, or longer engagement cannot use these screws. The hex key drive also requires the correct driver bit for installation and removal.

Simple installation with correct hex driver

Insert the appropriate hex key into the screw head and turn clockwise until the connection feels secure. Stripping the head is the most common issue, usually caused by using a worn or slightly undersized driver bit. Ensure the driver is fully seated before applying torque to maintain the precision fit.

Questions about this item

Should I choose the 4.5 mm diameter screws for my Sigma rig?

The 4.5 mm diameter matches the specification in the pack, so they fit the threaded holes on compatible Sigma support accessories without modification.

What does the 4.5 mm diameter mean once the screw is installed?

It gives a precise, secure fit that keeps stabiliser plates and mounting brackets from wobbling during handheld or tripod work.

What drive standard do these M3×6 screws use and what does it limit?

They use a hex key drive, which limits the tool to a matching hex wrench and caps the torque you can apply without rounding the recess.
