The Simpson ECCQ End Column Cap for 6-3/4 in. Beam and 4x Post with Strong-Drive SDS Screws is a Simpson Strong-Tie engineered connector built to deliver a high-capacity connection for column-beam combinations in wood construction applications. Formed from heavy-duty 7-gauge steel and finished in Simpson Strong-Tie gray paint, this end column cap gives engineers and contractors a reliable, code-friendly fastening solution designed and tested to perform at the highest quality standards.

Key Features

• Installs with included Strong-Drive SDS screws - eliminates the need to source separate fasteners and gets the connection done faster than traditional bolt-based methods
• SDS screws preserve greater net section area of the column compared to bolts - maintains more of the column's structural integrity at the connection point, supporting overall load capacity
• Low-profile SDS screw attachment - results in a cleaner, less obtrusive installation compared to standard through bolts, which is especially valuable in visible or finished applications
• Sized for a 6-3/4 in. beam paired with a 4x post - engineered for a precise fit with engineered lumber and heavy timber column-beam assemblies, reducing guesswork on the job
• Made from 7-gauge steel with Simpson Strong-Tie gray paint finish - provides durable construction and a consistent appearance across compatible Simpson Strong-Tie connector installations

Why This Product

• Engineered for high-capacity column-beam connections - this connector is purpose-built for end-of-beam applications where a strong, reliable column-to-beam tie is required, giving buyers confidence the connection is up to the structural demands of the project
• Faster installation with no extra hardware needed - the included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws mean crews can go straight to installation without hunting down compatible fasteners separately
• Trusted Simpson Strong-Tie engineering and manufacturing - designed, tested, and made to the quality standards that engineers and contractors rely on for both residential projects and code-compliant commercial construction
• Straps may be rotated 90 deg. - this built-in flexibility accommodates varying field conditions and framing orientations, reducing the need for workarounds or custom fabrication on site

Frequently Asked Questions

What beam width is the ECCQ74SDS2.5 designed to fit?

The ECCQ74SDS2.5 is specifically designed for use with a 6-3/4 in. wide beam in combination with a 4x post, making it ideal for engineered lumber and heavy timber column-beam applications.

What fasteners are used with this end column cap, and are they included?

This connector installs with 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws enable faster installation and provide a greater net section area of the column compared to standard bolts.

What are the advantages of SDS screws over standard through bolts?

Strong-Drive SDS screws provide a lower profile than standard through bolts, which results in a cleaner installation. They also allow attachment to a greater net section area of the column, improving the overall strength and integrity of the connection.

What material and finish is the ECCQ74SDS2.5 made from?

The ECCQ74SDS2.5 is manufactured from 7-gauge steel and features a Simpson Strong-Tie gray paint finish, providing durability suited for structural wood construction applications.
