Split washer or spring lock washer A ring split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener's head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to ...

This is mostly used to describe manually operated bolt action firearms, but also on some automatic firearms. The most common locking mechanism on rifles is a rotating bolt, which can be classified as a rigid type of bolt lock. Semi ...
This secondary spring rate dominates the spring rate of the bolt. Therefore a split lock washer can allow the bolted joint to take the same amplitude of vibration while maintaining more preload, which will result in a joint more resistant to loosening. I know that ASME B18.2.1 2009 does require the lock washer to be trapezoidal in shape.
Although bolt-action guns are usually associated with fixed or detachable box magazines, in fact, the first general-issue military breechloader was a single-shot bolt action: the paper-cartridge Prussian needle gun of 1841. France countered in 1866 with its superior Chassepot rifle, also a paper-cartridge bolt
To put lock time and bullet dwell time in perspective; the lock time of most conventional bolt action rifles varies between 2.6 and 9.0 milliseconds, while after cartridge ignition most rifle bullets travel through a high powered rifle barrel bore in 1.0 to 1.5 milliseconds. Mechanical bolt-action rifle trigger systems with a sub 2.0 ...
