Measuring and Fitting
Screw length is measured from beneath the head to the tip, excluding the head. Match these screws to a 1/4" UNF nut or tapped hole with 28 TPI and use a 3/16" Allen key for fitting.
The self colour finish has no protective plating. Consider suitable corrosion protection where the screws will be exposed to moisture.
