Would it be possible to have an electronic copy of the Metric to Imperial screw size chart that's on page 21 of the catalogue. I would like to print this out and keep a copy in my screw box.Thanks

Searching for screws I note that they state a 'ga' size. What does 'ga' mean? Have the 'ga' refer to the screw size I'd no.6 etc

Asked by: Icho
Hello Icho, The term 'ga' means gauge, it is a method of measuring metal. This screw is the equivalent 3.5 x 20mm in metric measurements. Thank you for using Q & A.
