How to choose size?
  • Please note that the Bolt length(L1) is fixed for M3-M8 to make sure the bolt can be fully screwed into the nut. The Nut thread depth(L3) is not the same as the L2. Please check detail on the size table.
  • If you need other length of the bolt to fix your special project thickness, please add the length you need in the order note, we can change for you for free.
  • For example, if your project thickness is 24mm, M3 size hole. The size only have M3-20mm or M3-25mm, you can choose M3-20mm size, and add a note for 8mm bolt, so that you can screw the bolt 4mm inside to achieve 24mm length.

Q & A

Hi, what size screw post hex bolts/sleeves do I need to mount the VD2053 800mm sliders to 18mm wood and the VD1551 600mm sliders to 12mm plywood? Is the M3 size the right diameter for the holes on the sliders? Thanks! Nicky asked on July 4, 2024

Hi!For your reference, both VD1551 and VD2053 are compatible with M3 screws.

Hello I need some fixings for some double sided panels that we are making. The panels are 62mm in thickness. Would your M4 nut bridge this distance and nip up tight. If not, what would you recommend. Thanks in advance. barnaby ward asked on February 1, 2024

Hi, you can use M4 nut, which bridges this distance and snaps tightly.

What is the diameter of the hole? Is the M4 dimension the diameter of the thread, or the diameter of the sleeve nut? Thank you Paul asked on June 13, 2023

Hi Paul,
The M4 is for the diameter of the sleeve nut holes and the screws. We have screws and nut in the pacakge. So they should matched.
