Frequently Asked Questions
- What does "predeflected" mean and why does it matter?
- The HDU4-SDS2.5HDG holdown body is pre-deflected during the manufacturing process, which virtually eliminates deflection under load due to material stretch. This results in a more stable and reliable connection in shearwall and lateral-load applications compared to standard holdowns.
- Why are SDS screws used instead of bolts?
- Strong-Drive SDS Heavy-Duty Connector screws install easily, reduce fastener slip, and provide a greater net section area of the post compared to bolts. They also eliminate the need to countersink stud bolts at openings, simplifying the installation process.
- Is this holdown suitable for exterior or treated-wood applications?
- Yes. The hot-dip galvanization (HDG) coating offers extra corrosion resistance, making the HDU4-SDS2.5HDG well suited for exterior environments and applications involving treated wood where standard coatings may be insufficient.
- Do the correct fasteners come with this holdown?
- Yes. The package includes (10) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws and (1) crescent washer, ensuring the proper fasteners are used for a code-compliant and correctly assembled installation. A 5/8 in. anchor bolt is also required for installation.
