Simpson ECCQ5-4HDG-SDS ECCQ HDG End Column Cap for 5-1/8 in. Beam, 4x Post, with Strong-Drive SDS Screws is an engineered Simpson Strong-Tie connector designed to provide a high-capacity connection for column-beam combinations in end-of-beam wood construction applications. The seat of the column cap extends beyond the side of the column to provide additional bearing surface area, helping distribute load from the beam and support the connection. Hot-dip galvanized for superior corrosion resistance, this end column cap is ideal for exterior and treated-wood applications where long-term durability is essential.

Key Features

• Uses Simpson Strong-Tie Strong-Drive SDS screws to provide faster installation and provides a greater net section area of the column compared to bolts
• SDS screws provide for a lower profile compared to standard through bolts
• The extended bearing seat distributes load from the beam beyond the side of the column for added connection support
• Certified welds for confidence in strength and loading
• Uplift loads have been increased for earthquake or wind loading
• Diamond holes for temporary fastening
• Beam width: 5-1/8 in.
• Made from 7-gauge steel
• Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications
• Manufactured in the United States

Frequently Asked Questions

What fasteners are used with the ECCQ5-4HDG-SDS, and are they included?

This end column cap is installed with 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. The package includes 14 screws for the beam connection and 14 screws for the post connection.

Why are SDS screws used instead of standard through bolts?

Strong-Drive SDS screws provide faster installation than through bolts and engage a greater net section area of the column. They also result in a lower profile connection compared to standard through bolts, which can be an important consideration in finished structural applications.

Is this end column cap suitable for use with pressure-treated lumber or exterior applications?

Yes. The hot-dip galvanized (HDG) finish provides extra corrosion resistance specifically suited for exterior applications and use with pressure-treated wood, making it appropriate for outdoor structures and environments where moisture exposure is a concern.

What beam and post sizes is this end column cap designed for?

The ECCQ5-4HDG-SDS is engineered for use with a 5-1/8 in. wide beam and a 4x post. The connector dimensions are W1: 5-1/4 in., W2: 3-5/8 in., L: 8-1/2 in., and H: 7 in., fabricated from 7-gauge steel.
