Review on Glarks M5X50Mm Security Stainless Resistant by Alan Estell

I replaced the original Trane screws on my new air handling unit access panel. I watched the assemblers tighten the original screws with an 18 volt cordless impact wrench, now they should be able to see me for the bit I taped onto the bit driver. No more warping or manipulating the panel. Update: someone used a regular T25 bit to unscrew them. Not as reliable as I thought.
