are allen screws having a captive screw or bolt such as a screw with a hexagonal hole in the head combined with fasteners designed for ease of installation u2014 often knurled for finger use u2014 and retained within their functional environment when not engaged captive screw or bolt retention prevents loss or damage within the captive screw 39 s parent assembly or damage to components in the nearby working environment the screw and captive bolt can connect apertures 20 of adjacent modular side frame members 12 or modular center frame members 13 frame 11 can be formed using one of modular side frame members 12 as a left hand side and a right hand side member which are basically the same regardless of whether frame 11 is to be made into a twin full queen or king size headboard in one embodiment modular side frame member 12 has a width w 1 of about 20 inches and modular center frame member 13 has a width w 2 of about 12 inches an appropriate number of modular side frame members 12 and modular center frame members 13 center sections can be coupled to one another to form frame 11 of an appropriate size support surface 18 can be attached to a front surface of frame 11 of modular side frame members 12 and modular center frame members 13 for example support surface 18 can be made of plywood for example frame 11 can be formed of hard wood fig2 b illustrates a twin frame embodiment including a pair of modular side frame members 12 connected to one another with a plurality of attachment members 21 no modular center frame members 13 are used in this embodiment for example three attachment.
