Answer :
Final answer:
The fastening system used to drive steel pins or threaded studs is the powder-actuated tool, which uses explosive forces to drive fasteners into hard materials. Other options like pneumatic screw nailers and air impact wrenches serve different purposes. The powder-actuated tool is optimal for this specific task.
Explanation:
Answer to the Fastening System Question
In identifying the correct fastening system used to drive steel pins or threaded studs, we must consider the options provided. Among the alternatives:
- Pneumatic screw nailer - Generally used for driving screws, not pins or studs.
- Powder-actuated tool - This tool uses a small explosive charge to drive fasteners into hard materials, such as steel or concrete.
- Air impact wrench - Primarily used for loosening and tightening bolts and nuts.
- Mini hammer drill - Mainly used for drilling holes and not specifically for driving pins.
Thus, the most suitable answer is the powder-actuated tool, as it is specifically designed to drive steel pins or threaded studs efficiently into hard surfaces. It's widely used in construction and other industrial applications where strong fastening is required.
