Special air vent bolts

Special air vent bolts1 Special air vent bolts2


These bolts are used when air vents are required for vacuum equipment, etc. There is a through hole for letting out the air which accumulates between the main body of the device and the screw.
We support both additional processing of commercially available bolts and special orders.
We also manufacture long bolts.

Points for use in manufacturing:

  • The longer the portion under the head is, the more difficult hole processing becomes.
  • It depends on the quantity, but additional processing of commercial bolts is usually cheaper.

We offer various solutions, so do not hesitate to consult us
