Measuring and Fitting
Countersunk screw lengths include the head. Choose a length that provides sufficient thread engagement with the nut or tapped hole, and prepare a suitable countersink where a flush finish is required.
Start threaded components by hand and fully seat the 2mm Allen key before tightening. When using a Nyloc nut, ensure the screw passes through the nylon locking insert.
Use the supplied washers beneath the nut or against a suitable flat bearing surface. Standard flat, spring and shakeproof washers are not intended to seat directly beneath a countersunk screw head.
