The Eaton Fuller hex flange cap screw, part number X8-688 or X8688, is a genuine Eaton fastener used in Eaton Fuller transmission and driveline assemblies. The integrated hex flange head spreads clamping load across a wider bearing surface, so no separate washer is needed at the joint. It is referenced under Eaton OEM number X-8-688 and cross part number HFX8-688. Because a cap screw like this is used in specific torque-critical locations, verify the fastener size and grade against your unit's parts breakdown before ordering. Not sure this is your part?
