Question

a toggle bolt is a good choice for which of the following activities?
bolting a chiller to the floor
mounting a safety warning sign
securing a blower wheel on a shaft
installing a compressor cylinder head

Explanation:

Toggle bolts are often used for light - duty mounting tasks on hollow walls. Mounting a safety warning sign is a light - duty task compared to the others which require more heavy - duty and specialized fastening. Bolting a chiller to the floor, securing a blower wheel on a shaft, and installing a compressor cylinder head need stronger and more specific types of fasteners due to the weight and stress involved.

Answer:

mounting a safety warning sign
