The Simpson ECCQ6-7.13SDS2.5 6x Beam 7x Post End Column Cap is a heavy-duty structural connector from Simpson engineered for end-of-beam column-to-beam connections in wood construction. Designed specifically for use with 6x beams and 7x posts, this end column cap features an extended bearing seat that projects beyond the side of the column to distribute load effectively from the beam, making it a dependable choice for heavy timber framing applications, as well as structural connections that must meet increased uplift demands from earthquake or wind loading.

Key Features

• Extended bearing seat design - projects beyond the side of the column to distribute load from the beam across a greater surface area, improving structural performance at the connection point
• Strong-Drive SDS Heavy-Duty Connector screws included - complete hardware for both beam and post connections is provided in the box, so installation can begin immediately without sourcing separate fasteners
• 7-gauge steel construction with Simpson Strong-Tie Gray Paint finish - delivers the material thickness and corrosion-resistant coating needed for demanding heavy timber and structural framing environments
• Lower-profile SDS screw fastening - eliminates the need for standard through bolts, allowing for a cleaner installation in applications where a reduced fastener profile is preferred or required
• Diamond holes for temporary positioning - allow the connector to be tacked in place before final fastening, reducing installation errors and improving accuracy during alignment
• Domestically produced by Simpson - supports consistent quality standards and is suited for code-confident structural connections in residential and commercial heavy timber framing

Why This Product

• Complete, ready-to-install package - the connector ships with 14 Strong-Drive SDS screws for the beam side and 14 for the post side, meaning everything needed for a fully fastened connection is included, reducing trips to the hardware store and keeping projects on schedule
• Built for high-uplift structural demands - approved for structural connections requiring increased uplift load capacity under earthquake or wind loading, making this cap a practical solution for projects in high-demand seismic or wind zones
• Purpose-built fit for 6x beam and 7x post combinations - the connector is specifically sized for this beam-and-post pairing, eliminating the guesswork of adapting a general-purpose connector and ensuring a properly engineered fit from the start
• Simplified fastening with no through bolts required - the SDS screw-based installation is faster to execute than traditional bolt-through methods, saving labor time while still delivering the structural integrity required for heavy timber column cap connections

Approved Applications

• End-of-beam column-to-beam connections in wood construction
• Structural connections requiring increased uplift load capacity for earthquake or wind loading
• Applications where a lower-profile fastener is preferred over standard through bolts
• Heavy timber framing connections involving 6x beams and 7x posts

What's Included

• 1x ECCQ6-7.13SDS2.5 End Column Cap
• 14x 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws (Beam)
• 14x 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws (Post)

Installation

Fasten with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the connector. The extended bearing seat should be positioned to project beyond the side of the column to maximize load distribution from the beam. Use diamond holes for temporary fastening during positioning prior to final installation.

Frequently Asked Questions

What beam and post sizes is the ECCQ6-7.13SDS2.5 designed to fit?

This end column cap is designed for use with a 6x beam and a 7x post. It accommodates a beam width of 5-1/4 or 5-1/2 inches, with a W1 dimension of 5-1/2 inches and a W2 dimension of 7-1/8 inches.

What fasteners are included, and why are they preferred over standard bolts?

The ECCQ6-7.13SDS2.5 comes complete with Strong-Drive SDS Heavy-Duty Connector screws. These 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, resulting in a fast, secure, and code-confident installation.

What are the overall dimensions of this column cap?

The connector measures 8-1/2 inches in length (L), 7 inches in height (H), 5-1/2 inches for dimension W1, and 7-1/8 inches for dimension W2.

What material and finish is this column cap made from, and does it include any quality assurance features?

The ECCQ6-7.13SDS2.5 is fabricated from 7-gauge steel with a Simpson Strong-Tie Gray paint finish. It features certified welds for confidence in strength and load performance, and uplift loads have been increased for earthquake or wind loading applications.
