Simpson HCA Hinge Connectors - Custom Order Part by Simpson Strong-Tie are engineered hinge connectors designed to transfer loads between two beams aligned end-to-end. Combining bearing plates, side plates, and bolts, these connectors support vertical loads and can be configured to resist horizontal loads as part of a continuous load path, making them a versatile solution for heavy timber framing and structural beam connections.

Key Features

• Transfers loads between two beams aligned end-to-end through a combination of bearing plates, side plates, and bolts
• Supports vertical loads and can be specified with additional slotted bolt holes to resist horizontal loads as part of a continuous load path
• Can be ordered to accommodate dapping or notching on the top of the beam
• Side plates constructed from 7-gauge material for robust structural performance
• Finished in Simpson Strong-Tie gray paint for durability
• Available in heights up to 60"; contact Simpson Strong-Tie for greater heights
• Slotted bolt holes allow positioning of 3/4"-diameter bolts away from the bearing seat to accommodate wood shrinkage

Frequently Asked Questions

What types of loads can the Simpson HCA Hinge Connector resist?

The HCA Hinge Connector is designed to transfer loads between two beams aligned end-to-end. In addition to supporting vertical loads, it can be specified with additional slotted bolt holes to resist horizontal loads as part of a continuous load path.

Can the HCA Hinge Connector be used with dapped or notched beams?

Yes. The HCA can be ordered to accommodate dapping or notching on the top of the beam. For dapped beams, the H dimension should be reduced by the PT dimension for each dap.

What are the bolt hole size requirements for installation?

Per 2015/2018 NDS 12.1.3.2, bolt holes must be a minimum of 1/32" and a maximum of 1/16" larger than the bolt diameter. Additionally, 3/4"-diameter bolts in slots should be positioned away from the bearing seat to allow for wood shrinkage.

Are there height limitations for the HCA Hinge Connector?

Standard configurations are available for heights up to 60". For heights greater than 60", contact Simpson Strong-Tie directly for assistance with your specific application.
