Aircraft Tool Supply Brass Compass Screwdriver

This is very well made and is definitely non-magnetic. The blade is a nice fit for the adjustment screws in an aviation-type compass.

This was exactly what I needed to swing my compass. Non-ferrous screwdriver perfectly sized for my PAI 700 compass card. It's a bit pricey but worth it for me as I could not source this locally and needed it quickly.

Very useful flathead for use in sensitive areas where a non-magnetic screwdriver is needed. Good for compass/magnasyn installs

This well-made special purpose tool handles properly and does what it is supposed to do. Remember that it is made of relatively soft brass and can't be used to tighten steel screws, at least not very tight. Brass screwdrivers are for the purpose of making adjustments, not tightening.

Love this tool. I purchased one for each of my MTP friends and gave them as Christmas presents. It's nice to have the right tool for the job.

Primary purpose of this screwdriver is that it's non-magnetic (brass) and used for adjusting stand-by compasses. This is a light duty screwdriver and should be used as a precision tool. The tip of the shaft dimension is: .1562" (5/32") Wide, by .0350" (a hair over 1/32") thick. Other dimensions are: 4 3/4" overall length, knurled handle is 2" x 1/2", shaft 2 3/4" x 5/32".

Good screwdriver works for what it intended for non-magntic work

Used to calibrate my PAI-700 vertical card compass. Fit the screws perfectly and is definitely non magnetic (brass).
