Dead bolt combination lock having an inexpensive lock mechanism, of a type known in the luggage industry, that cooperates with a one-piece bolt. The bolt is supported for reciprocative movement on internal shoulders of a housing and forms a detent device with a resilient arm of a back cover of the housing, so that the bolt is releasably held in its locked and unlocked positions. The bolt is locked in one of those positions when the combination lock is off-combination. The configuration of the bolt resists bending, and a projecting portion of the bolt contains a case-hardened pin that can rotate to resist sawing through the bolt.
