An automotive technician must select the appropriate hand wrench for various workshop maintenance tasks. Match each wrench type to its primary mechanical application.
- Hex key (Allen wrench)Driving fasteners designed with an internal recessed six-point socket
- Strap wrenchTurning smooth, cylindrical components without marring or crushing the surface
- Offset box-end wrenchProviding full enclosure around a hex head while lifting the handle above surface obstructions
- Open-end wrenchSliding directly onto fastener flats from the side when vertical overhead clearance is blocked
Cevap
Hex key matches driving fasteners with internal recessed six-point sockets; Strap wrench matches turning smooth cylindrical components without surface damage; Offset box-end wrench matches providing full hex enclosure while clearing surface obstructions; Open-end wrench matches sliding onto fasteners laterally under restricted overhead clearance.
Each wrench is engineered for distinct mechanical constraints and fastener profiles: hex keys engage internal hexagonal recesses, strap wrenches rotate smooth cylindrical bodies via friction grip, offset box-end wrenches provide 360-degree fastener contact while elevating the handle for clearance, and open-end wrenches permit lateral access when overhead space is restricted.

Anahtar Kavram
Wrench selection criteria based on fastener drive geometry, clearance angles, and component surface profiles.
