U.S. Patent Specifications

In devices for securing structural members together, the combination with a nut‐containing fastening strip comprising a channel member having a web and side flanges, of a nut having a screw‐threaded bore, said nut comprising a body portion and a laterally enlarged base portion, said base portion being housed within said channel member, the web of the channel member being provided with an aperture into which the body portion of the nut extends, the laterally enlarged base portion of the nut being adapted to engage the side flanges of the channel member to prevent relative rotary movement between the nut and channel member and to engage the said web to prevent the nut from passing completely through the aperture in the web, the side flanges of the channel member having inwardly‐turned edge portions forming a base to the channel member to secure the nut to the channel member against removal, the said base of the channel member having a bolt‐receiving aperture of such size as to register with the bore of the nut and a threaded bolt for insertion, in the order named, through a plurality of structural members, the base of the channel member, and the threaded bore of the nut, whereby the base of the channel member may be frictionally gripped between the base portion of the nut and the adjacent structural member to resist spreading of the channel member by rotation of the nut.
