The Simpson Strong-Tie ECCQ48-SDS2.5HDG is a heavy-duty, hot-dip galvanized end column cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction projects. Designed for use with a 4x beam and 8x post, this column cap features an extended seat that provides additional bearing surface beyond the side of the column, helping to effectively distribute loads from the beam while supporting the integrity of the connection. Fabricated from 7-gauge steel with a hot-dip galvanized finish for superior corrosion resistance, the ECCQ48-SDS2.5HDG comes complete with Strong-Drive SDS Heavy-Duty Connector screws for fast, efficient installation and enhanced net section attachment to the column.

Key Features

• Extended Bearing Seat: The seat of the column cap extends beyond the side of the column to distribute beam loads across a greater surface area, providing reliable support at the connection point.
• Strong-Drive SDS Screws Included: Comes with 1/4" x 2-1/2" SDS Heavy-Duty Connector screws - 14 for the beam and 14 for the post - enabling fast installation without the need for through bolts.
• Lower Profile Fastening: SDS screws deliver a lower profile than standard through bolts, resulting in a cleaner, more streamlined installation.
• Certified Welds: Features certified welds for confidence in connection strength and load performance.
• Increased Uplift Load Capacity: Uplift loads have been increased to meet demands associated with earthquake or wind loading conditions.
• Diamond Holes for Temporary Fastening: Diamond-shaped holes allow for quick temporary fastening during installation.
• Hot-Dip Galvanized Finish: The HDG finish provides excellent resistance to corrosion, making this column cap suitable for demanding environments.
• 7-Gauge Steel Construction: Heavy-duty steel gauge ensures durability and structural integrity under load.

Frequently Asked Questions

What beam and post sizes is the ECCQ48-SDS2.5HDG designed to fit?

This end column cap is designed for use with a 4x beam and an 8x post, making it suitable for heavy-duty wood construction applications where those specific lumber dimensions are used.

What fasteners are included, and do I need to purchase additional hardware?

The ECCQ48-SDS2.5HDG comes complete with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws - 14 for the beam and 14 for the post - so no additional through bolts or fasteners are required for installation.

What material and finish does this column cap use, and is it suitable for outdoor or exposed applications?

This column cap is fabricated from 7-gauge steel with a hot-dip galvanized finish, which provides superior corrosion resistance, making it well suited for outdoor and exposed wood construction environments where moisture and the elements are a concern.

What is the purpose of the extended bearing seat on this column cap?

The extended bearing seat projects beyond the side of the column, distributing beam loads across a greater surface area at the connection point. This design helps support the integrity of the connection and provides reliable load transfer in end-of-beam applications.
