Frequently Asked Questions

Which anchor models is the HDIASTS31-37 setting tool compatible with?

This setting tool is specifically designed for use with Simpson Hollow Drop-In Anchor models HDIA31, HDIA37, and HDIA37SS, covering the 5/16-inch and 3/8-inch anchor size range.

What base materials can this setting tool be used in?

The HDIASTS31-37 is designed for use in solid materials, including brick, normal-weight concrete, and lightweight concrete. It is not intended for use in hollow or cavity-type base materials.

What is the purpose of using a dedicated setting tool rather than improvising with another instrument?

Using the correct setting tool ensures that the hollow drop-in anchor expands fully and uniformly within the base material, strongly reinforcing the anchor to create a secure, load-ready connection. Improvised tools may result in incomplete expansion and compromised holding values.

What types of suspension systems is this tool commonly used for?

This setting tool supports installations where threaded rod is used to suspend systems such as electrical cable trays, HVAC ductwork, and fire sprinkler pipe and sprinkler heads from solid overhead substrates like concrete or brick.
