Truck bed mounting bolts for 1988-1998 Chevrolet/GMC OBS

Eight mounting bolts for an OBS pickup bed

This set supplies eight silver-colored steel bolts for selected 1988-1998 Chevrolet and GMC full-size C/K pickup bed applications. Each bolt has a hex flange head and a threaded shaft. The listed range includes 2WD and 4WD trucks, subject to matching the actual bed mounting hardware.

Use the set when replacing bed mounting bolts or refitting a removed pickup bed with compatible mounting points. Before ordering, compare the original bolts and count the positions that need replacement. The cab configuration, bed style and length, and any changes to the bed or frame should be checked individually.

Compare the bolts at each mounting point

Confirm the required thread diameter and pitch, length under the head, flange size and bolt strength specification against the truck's service information. Check the receiving threads and the space behind each mount so the bolt can engage correctly without bottoming out. An OBS designation or a matching drive type alone is not enough to select the hardware.

Inspect the bed supports, frame mounting points and any isolators or spacers used by the original assembly. New bolts do not repair damaged supports or stripped receiving threads. Keep the mounting stack appropriate to the specific truck and confirm any additional parts needed before starting work.
