Custom Vented Screws In Invar 36 Material - 8-32 X 5/8 And 6-32 X 1/4

Both of these custom vented screws are recurring parts for a research lab we work with.  Measuring 8-32 X 5/8 and 6-32 X 1/4 both are made using Invar 36 material with a vent drilled hole running the full length of the screw.  Invar 36 material has a very low level of thermal expansion and is typically used for applications where dimensional changes due to temperature variation must be minimized as much as possible.  The hex socket drive was broached for both parts, in lieu of a cold headed alternative.

Custom Metric Invar Screws - M2.5 X .45M X 8MM Socket Head Cap Screws in Invar 36 Material

These are the other version of the custom metric invar screws that we supply to the University of Montreal, typically at approximately 50 pieces per order.  Plain invar 36 material is used for the domestic production of the parts and lead time typically ranges from 2 to 3 weeks from confirmed order placement.  Material certs, FAIR, and certificate of conformance are available with the parts upon request.
