Believe it or not, the screw is actually considered a simple machine. It converts rotational motion into linear motion by way of its helical grooves, more commonly known as threads. As most people are aware, it is generally used as a fastener.
The G3 grip screw is no exception. It is a screw manufactured by Heckler & Koch to be used specifically with the G3’s pistol grip and is compatible with the HK91 and the PTR91 as well. The purpose of this screw is to secure the pistol grip to the rifle’s lower receiver/trigger pack.
The screw may seem like an insignificant component of your firearm but that line of thinking is quite wrong. Since screws are subject to inertia during the operation of a firearm, the threads are susceptible to damage. Screws may also show evidence of previous repair work. Additionally, the wrong screw may leave the most scrutinous collectors feeling as if a firearm is not correct.
As you can see, screws are very important pieces of any firearm. If you’ve ever dealt with a damaged screw or a loose grip, consider this package of 10 original HK grip screws and rest assured knowing that another part of your G3 is correct.

The screw is one of six simple machines. The lever, wheel and axle, pulley, inclined plane and wedge comprise the other five. It is unknown when the screw was invented, but first appeared in ancient Greece. Early uses included the screw press and the Archimedes screw, a form of water pump used to move water from low-lying areas to higher areas. It is believed to have first been used a fastener in clocks during the 1400s.
