Simpson ECCQ44-SDS2.5HDG ECCQ HDG End Column Cap for 4x Beam, 4x Post, with Strong-Drive SDS Screws is a hot-dip galvanized column cap engineered by Simpson Strong-Tie to deliver reliable column-to-beam connections in end-of-beam applications in wood construction. The extended bearing seat distributes load beyond the side of the column for superior structural support, while included Strong-Drive SDS Heavy-Duty Connector screws enable fast installation and engage a greater net section area of the column than standard bolt attachments.

Key Features

• The SDS screws provide a lower profile than standard through bolts
• Certified welds for confidence in strength and loading
• Uplift loads have been increased for earthquake or wind loading
• Diamond holes for temporary fastening
• Nominal beam width: 4x
• Nominal post size: 4x
• Made from 7-gauge steel
• Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications
• Seat provides additional bearing surface area extending beyond the side of the column to help distribute load from the beam
• Eliminates the need for additional brackets or braces in compatible applications

Frequently Asked Questions

What type of fasteners are used with the ECCQ44-SDS2.5HDG, and are they included?

This column cap installs using 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212). A full set of 28 screws - 14 for the beam and 14 for the post - is included with the connector.

Why are SDS screws preferred over standard through bolts for this connector?

The Strong-Drive SDS screws provide a lower profile than standard through bolts and attach to a greater net section area of the column, resulting in a stronger, cleaner connection without the need for drilling through-bolt holes.

Is the ECCQ44-SDS2.5HDG suitable for exterior or treated-wood applications?

Yes. The hot-dip galvanized (HDG) finish provides enhanced corrosion resistance, making this column cap well suited for exterior environments and applications involving treated lumber.

Does this column cap offer any resistance to earthquake or wind uplift forces?

Yes. The ECCQ44-SDS2.5HDG features increased uplift load ratings specifically to address the demands of earthquake and wind loading conditions, providing added confidence in high-load structural applications.
