The Simpson 3/8" Heli-Tie Replacement Test Key is a purpose-built accessory designed specifically for use with the Heli-Tie wall tie tension tester. Engineered to grip the Heli-Tie fastener securely during tension testing, this key from Simpson helps ensure accurate load value determinations and reliable installation results when verifying wall tie performance onsite in any specific structure.

Key Features

• Purpose-built fit for the Heli-Tie tension tester - designed specifically for this application, so the key works as intended without improvisation or workarounds during onsite testing.
