The Simpson ECCQ64SDS2.5 End Column Cap is an engineered structural connector from Simpson built to deliver a high-capacity connection for column-beam combinations in end-of-beam wood construction applications. Designed for use with a 6x nominal beam and a 4x post, this end column cap is fabricated from 7-gauge steel and arrives ready to install with included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws - giving contractors and builders a reliable, code-conscious solution trusted by engineers on residential and commercial framing projects alike.

Key Features

• Installs with included Strong-Drive SDS screws - eliminates a separate fastener purchase and speeds up installation while preserving greater net section area of the column compared to standard through bolts
• SDS screws produce a lower profile than through bolts - keeps connections cleaner and reduces interference with surrounding structural elements for a neater finished assembly
• Sized for a 6x nominal beam width - precisely matched beam and post sizing ensures a secure, properly fitted connection without field modification
• Constructed from 7-gauge steel - heavy-gauge material supports the high-capacity load demands expected of column-to-beam connections in structural applications
• Finished in Simpson Strong-Tie gray paint - provides a consistent, protected surface suited to typical covered structural environments

Why This Product

• Faster installation without sacrificing strength - the included Strong-Drive SDS screws drive quickly without pre-boring for through bolts, cutting labor time while delivering a high-capacity structural connection
• Engineered and tested by Simpson - Simpson connectors are manufactured to meet rigorous quality standards and are the choice of engineers and contractors for projects that must perform to code
• Hardware included right out of the box - the 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws are included, so installation can begin immediately without sourcing separate fasteners
• Purpose-built for end-of-beam column applications - the ECCQ end column cap geometry is specifically designed for the structural demands of beam-end and post-top connections, making it a straightforward fit for pergolas, decks, carports, and similar framed structures

Frequently Asked Questions

What size beam and post is the ECCQ64SDS2.5 designed for?

The ECCQ64SDS2.5 is designed for use with a 6x nominal beam width and a 4x post, making it specifically suited for column-beam combinations in end-of-beam wood construction applications.

What type of fasteners are used to install this end column cap?

This column cap is installed using 1/4 in. x 2-1/2 in. Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws provide faster installation and a greater net section area of the column compared to standard through bolts.

What is the advantage of using SDS screws over standard through bolts?

Strong-Drive SDS screws provide a lower profile compared to standard through bolts and allow attachment to a greater net section area of the column, resulting in a stronger, cleaner, and faster-to-install connection.

What material and finish is the ECCQ64SDS2.5 made from?

The ECCQ64SDS2.5 is manufactured from 7-gauge steel and features a Simpson Strong-Tie gray paint finish, providing durability and consistent quality meeting Simpson Strong-Tie's high manufacturing standards.
