Tinnerman Bolt Retainers eliminate problems of blind location, bolt retention, threaded stud damage, paint-clogged threads, weld flash and difficult assembly or removability wherever threaded studs may be used. They can be attached after finishing and just before final assembly to eliminate thread damage due to stacking, weld flash, paint clogging, etc. One type is mounted from the front to ease assembly in blind or difficult locations. Both are self-retained and can be easily removed and replaced without damage to the mounting panel. Access to the underside of the panel is unnecessary because the bolt cannot turn as the nut is driven to its prescribed torque. A shallow emboss allows flush mounting of mating panels.
