Frequently Asked Questions
- What makes the HDU14-SDS2.5 different from holdowns that use bolts?
- The HDU14-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws instead of bolts. These screws install easily, reduce fastener slip, and provide a greater net section area of the post compared to bolts, resulting in a stronger and more reliable connection.
- What does "predeflected" mean and why does it matter?
- Predeflected means the holdown body is deflected during the manufacturing process before it is ever installed. This virtually eliminates deflection under load due to material stretch, ensuring the connection maintains its integrity and performance over time.
- What material and corrosion protection does this holdown have?
- The HDU14-SDS2.5 is made from 7-gauge steel and finished with a Zinc Galvanized (G90) coating, providing extra corrosion resistance for long-term durability.
- Do I need to purchase fasteners separately for the HDU14-SDS2.5?
- No. The HDU14-SDS2.5 comes supplied with (36) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws, (1) crescent washer, and (1) heavy-hex anchor nut, ensuring the proper fasteners are always used with this holdown.
