Embodiments of the present disclosure provide for systems, apparatuses, and methods of securing screen assemblies. Embodiments include a system having a compression assembly with a compression pin and a pin assembly having a pin. The compression assembly may be attached to a first wall member of a vibratory screening machine and the pin assembly may be attached to a second wall member of the vibratory screening machine opposite the first wall member such that the compression assembly is configured to assert a force against a first side portion of a screen assembly and drive a second side portion of the screen assembly against the pin of the pin assembly. The pin assembly may include a pin that is internally or externally mounted and that is adjustable and/or replaceable.
