Simpson ECCQ5-6SS-SDS2.5 End Column Cap by Simpson Strong-Tie is a 5-1/8" beam width, 6x post end column cap engineered to provide strong column-beam connections in end-of-beam applications in wood construction. Fabricated from 3-gauge stainless steel with a stainless steel finish, this connector delivers reliable performance in demanding structural environments while resisting corrosion over the long term.

Key Features

• The seat of the column cap provides an additional surface area of bearing that extends beyond the side of the column, helping distribute the load from the beam and provide support for the connection
• 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
• Uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation and attachment to a greater net section area of the column than a bolt attachment normally entails
• Made in the United States

Frequently Asked Questions

What type of fasteners are used with the ECCQ5-6SS-SDS2.5?

This column cap is installed using 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are included with the connector. A total of 28 screws are provided - 14 for the beam and 14 for the post.

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 than a bolt attachment normally entails, which contributes to a stronger and cleaner connection.

What is the purpose of the extended bearing surface on the ECCQ column cap?

The seat of the column cap extends beyond the side of the column to provide an additional surface area of bearing. This extended bearing surface helps distribute the load from the beam and provides greater support for the overall connection.

Is this column cap suitable for use in high-wind or seismic applications?

Yes. Uplift loads on the ECCQ have been increased specifically to accommodate earthquake or wind loading conditions, making it appropriate for use in regions subject to these structural demands.
