Improving An Angle Tightening Attachment

Jacques Maurel improves an inexpensive but unreliable angle gauge

- Jacques Maurel

How it works

We often want to measure a tightening angle after the contact of the screw head with its mating part, a common way of applying a suitable screw tension without using a torque wrench. The accessory shown in photo 1 is readily available, but of cheap construction.

The attachment body (1) is basically a standard male/female 1/2” square junction, photos 2 & 3.
