setscrew

You insert the sight and tighten the setscrew holding it firmly in place.

In one case, the large setscrew was off-center, while the .32-40's barrel was frozen on with decades of oil that had turned to varnish.

Loosen a setscrew and raise or lower the sight on its ramp to adjust elevation; loosen a different screw to adjust windage.

I did need to tighten one setscrew to prevent some initial slippage of the fine focus knob, but after that the Meade focuser worked consistently well.

The four sides of its stainless-steel sear give you the choice of no-click, short-click, medium-click or long-click settings, and each has a long hot/cold adjustment range so you can customize it to your personal travel preference via a setscrew. The anodized-aluminum release head is precision machined to guarantee perfect engagement of the sear and the stainless-steel string hook.

This design provides clearance from the burr created by the setscrew used to lock the bearing to the shaft, which makes removal difficult and can cause damage to the shaft during removal.

The rear sight is drift adjustable via a setscrew, and Smith & Wesson has done a good job balancing robust build quality and functional size with a snag-free design.

Tension on the gears can be adjusted with a setscrew. The curled metal pate apparently guides material into the gears.

Then position the connector so that the setscrew is a quarter turn counterclockwise from the front of the box.

I do recommend adding a setscrew; this would mean having to drill a hole through the bracket, so you can place a screw through the branch to hold it in place.
