The Simpson Hidden Timber Connector Kit with Screws (ETB160A-SCRB) delivers a clean, professional beam connection without any visible hardware - preserving the natural aesthetic of exposed timber framing while maintaining a fully load-tested structural connection. Interlocking plates are fastened onto each member and lock together to form a secure, concealed joint ideal for architectural timber applications where appearance and structural integrity are equally important.

Key Features

• Completely Hidden Hardware: Interlocking plate system conceals all fasteners once installed, leaving no visible connector hardware on the finished assembly.
• Load-Tested Beam Connection: Engineered for reliable structural performance with a fully tested interlocking plate design.
• Interlocking Plate System: Upper and lower plates fasten independently to each member, then lock together for a secure and stable connection.
• SCRB Screws Included: Kit ships complete with SCRB structural screws for the horseshoe plate installation - no additional fastener purchase required for that component.
• Angled Screw Installation: SCRB screws are installed at a downward angle (approximately 45 deg.) for optimized load transfer and pull-through resistance.
• Routed Pocket Design: Lower plate seats into a 3/8" (10 mm) deep routed pocket in the side of the supporting beam for a flush, concealed fit.

Frequently Asked Questions

Does the ETB160A-SCRB kit include the screws needed for installation?

Yes, the kit ships complete with SCRB structural screws for the horseshoe plate installation, so no additional fastener purchase is required for that component.

Will any connector hardware be visible once the ETB160A-SCRB is installed?

No. The interlocking plate system conceals all fasteners once installed, leaving no visible connector hardware on the finished assembly - making it well suited for architectural timber applications where appearance matters.

How does the lower plate fit flush within the supporting beam?

The lower plate seats into a 3/8" (10 mm) deep routed pocket cut into the side of the supporting beam, allowing it to sit flush and remain fully concealed after the connection is made.

At what angle are the SCRB screws installed?

The SCRB screws are installed at a downward angle of approximately 45 deg., which is designed for optimized load transfer and pull-through resistance.
