A fastening device and method for mounting equipment to a framing member. The invention includes a single breakaway fastener that is pretentioned using a biasing member to fracture on a predetermined force applied to the fastened joint to avoid damage to the secured equipment. In one example the device and method includes the fastener having a reduced diameter portion that is positioned between an annular plate and the framing member.

Single retainer mounted riser

A motor vehicle car body framing apparatus for use at a welding station, the apparatus including a gate having a frame structure and a plurality of tooling members carried by the frame structure for use in positioning components of the vehicle body at the welding station for welding. The tooling members are mounted on the frame structure by a plurality of mounting brackets. Each mounting bracket includes a base member mounted on the frame structure and a riser mounted on the base and mounting a respective tooling member. The riser is fixedly mounted on the base by a single central fastener bolt which may include a reduced diameter portion sized to breakaway in response to predetermined impact against the riser. The interface between the riser and the base comprises a plurality of contact points arranged in concentric relation with respect to the fastener bolt. The contact points may comprise a plurality of circumferentially spaced balls mounted on the base for coaction with circumferentially spaced grooves defined on the riser. A breakaway bolt assembly replacement kit is also disclosed as well as an arrangement wherein the riser is constituted by an integral extension arm of the tooling member.
