Difficulty: EasyGripping and Holding Tools

A technician needs to hold two flat pieces of metal tightly together on a workbench to prevent them from moving while drilling a hole through both pieces. Which of the following tools is best designed for securely holding these workpieces together?

  1. A
    Phillips screwdriver
  2. B
    Adjustable open-end wrench
  3. C-clampAnswer
  4. D
    Flat hand file

Answer

The C-clamp is the appropriate tool for securely holding flat workpieces together.
The C-clamp is specifically designed to provide strong, stationary holding pressure to clamp multiple workpieces together securely against a surface or to each other while operations such as drilling, cutting, or gluing are performed.

Step-by-Step Solution

1
Identify the primary requirement of the task described in the scenario.
The task requires holding two flat pieces of metal stationary and firmly pressed together during a machining/drilling operation.
Secure workpiece holding prevents slipping, uneven drilling, and potential shop injury.
2
Evaluate the functional category and mechanics of the available hand tools.
The C-clamp provides rigid stationary clamping pressure via its threaded screw and fixed frame, whereas screwdrivers drive fasteners, wrenches turn bolt heads, and files cut material.
Selecting the dedicated holding tool ensures proper clamping force and workpiece stability.
