Adjustable X Type Manual Bolt Hole Probe

Manual bolt hole probes have coils that are positioned at right angles to the probe’s shaft length. The probes are rotated by hand inside the bolt hole with the fastener removed. 

These probes are available in an absolute (single coil) configuration with a Microdot connector or in a bridge or bridge differential configuration utilizing a Fischer/LEMO Triax connector. These probes feature a plastic tip and body for maximum durability. All probes have a split tip, allowing them to expand beyond the indicated nominal diameter range.
