Peter G. Kokalis of Soldier of Fortune magazine and Shotgun News wrote that he installed over 300 Vortex Flash hiders while working as a military advisor with a Central American paramilitary unit in the 1980s. [7] The Vortex Flash Hider is used by the US Military on M4 carbines and M16 rifles with the NATO Stock Number of NSN 1005-01-591-5825 ...
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 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.
A positive locking device is a device used in conjunction with a fastener in order to positively lock the fastener. This means that the fastener cannot work loose from vibrations. The following is a list of positive locking devices: [1] A split beam nut; A castellated nut and a split pin; A hex nut or cap screw and a tab washer
A car hub showing a castellated nut cover and split pin (near center) Split pins are frequently used to secure other fasteners, e.g. clevis pins, or to secure a castellated nut, [6] or, infrequently, as a low-tech shear pin. Split pins are cheaper but less reusable than linchpins, and provide less strength but easier to install/remove than ...

A turn bolt refers to a firearm component where the whole bolt without using a bolt carrier turns to lock/unlock. 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 ...
A lock washer is used to prevent a screw, bolt, or nut from loosening under vibration. It operates as a spring under compression having sufficient elasticity to neutralize the play between the assembled parts that vibration causes. [3] National licensed five other washer manufacturers under the patent.
