The Simpson Wall Tie Tension Testing Kit for 3/8 in Heli-Tie from Simpson Strong-Tie is the recommended onsite solution for accurately determining the load values of 3/8 in Heli-Tie helical wall ties in any specific structure. Whether you are a contractor verifying tie performance in an existing masonry wall or an engineer confirming installation integrity, this kit delivers everything needed to conduct reliable, job-site tension tests with confidence.

Key Features

• Onsite load value determination - allows contractors and engineers to test actual pull-out resistance in any specific structure, removing guesswork and supporting accurate project documentation.
• Dedicated grip key for the Heli-Tie fastener - the included key is purpose-built to seat securely on the helical tie, ensuring consistent contact and repeatable, trustworthy test readings.
• Compatible with the 3/8 in Heli-Tie helical wall tie system - designed specifically for this fastener size, eliminating compatibility concerns and streamlining your testing workflow.
• Protective carrying case included - keeps the tension tester and grip key organized, protected from jobsite damage, and ready for transport between locations.
• Recommended testing equipment from Simpson Strong-Tie - sourced directly from the manufacturer of the Heli-Tie system, so the kit is engineered to work precisely with the ties it tests.

Why This Product

• Manufacturer-matched accuracy - because this kit comes from Simpson Strong-Tie, the same brand behind the Heli-Tie system, every component is engineered to interface correctly with the 3/8 in helical tie, giving you test results you can rely on.
• Saves time on complex masonry projects - performing tension tests directly at the job site means faster decision-making on wall tie adequacy without waiting on off-site lab evaluations.
• Purpose-built for helical wall tie tension testing - rather than adapting a general-purpose tester, you get a kit designed from the ground up for this specific application, reducing setup errors and improving overall test confidence.
• All-in-one kit, ready to deploy - the tension tester, grip key, and protective carrying case arrive together, so your team can move from unboxing to testing without sourcing additional components.
