M&M Explosion Venting Fasteners are used in the construction of certain metal building environments. These environments may contain potentially hazardous material or operations which may pose an explosion threat. M&M Explosion Venting Fasteners assist in allowing explosive forces to escape or vent from the building.

The M&M Fastener System consists of a fastener-washer assembly with special aluminum alloy washers bonded with EPDM rubber to provide a weather tight seal. Certain applications require a centering device to prevent panel sag.

M&M Explosion Venting Fasteners are identified by a color code on the fastener body, which allows the head and washer to be color matched to any panel color.
