The Simpson META20Z ZMAX Galvanized Embedded Truss Anchor from Simpson delivers an engineered connection between roof trusses and concrete or masonry walls, offering proven performance where structural reliability matters most. Built from 18-gauge steel with a ZMAX galvanized finish, this medium embedded truss anchor is load rated for wind and seismic forces and can be installed straight or field-bent around truss or rafter members - giving contractors a flexible, high-performance anchoring solution for both single- and multi-ply truss applications.

Key Features

• Indented embedment line - provides a clear visual guide during installation, eliminating guesswork and helping ensure accurate, code-compliant embedment depth every time
• Load rated for wind and seismic forces - independently tested to perform under the lateral and uplift loads that matter most in high-wind and seismic zones, giving builders confidence in structural compliance
• 16-in. exposed length with 4-in. embed depth - sized to work with a 6-in. minimum concrete beam or 8-in. nominal grouted block wall, covering the most common masonry wall construction scenarios
• Staggered nail pattern - strategically designed to strengthen uplift resistance, so the connection holds firm under the demanding forces a roof truss experiences over time
• 18-gauge steel construction - provides the structural rigidity needed for dependable truss-to-wall connections without adding unnecessary bulk to the installation
• ZMAX galvanization - delivers extra corrosion resistance specifically engineered for exterior environments and applications involving treated wood, extending the service life of the anchor
• Straight or field-bent installation - adapts to varying jobsite conditions and truss or rafter configurations without requiring special tooling, saving time in the field
• Compatible with Simpson TSS truss seat snap-in and TBP8 moisture barrier plate - works within a broader system of coordinated accessories to address moisture management and seating needs in a single, integrated approach

Why This Product

• Engineered for the toughest structural demands - the META20Z is load rated for both wind and seismic forces, making it a go-to anchor for residential and light commercial roof framing projects where code compliance and long-term performance are non-negotiable
• Versatility built in from the start - the ability to install straight or field-bend around truss or rafter members, combined with compatibility for single- and multi-ply trusses when used in pairs, means one anchor model covers a wide range of framing situations
• ZMAX coating for demanding conditions - where standard galvanization falls short, the ZMAX finish provides the elevated corrosion protection needed for exterior exposure and treated-wood contact, reducing maintenance concerns and protecting long-term structural integrity
• Accuracy designed in, not left to chance - the indented embedment line takes the uncertainty out of setting depth in concrete or grouted block walls, helping crews work faster and with greater precision on every anchor set

Frequently Asked Questions

What is the exposed length and required embed depth of the META20Z?

The META20Z has a 16-in. exposed length and must be embedded 4 in. into either a 6-in. minimum concrete beam or an 8-in. nominal grouted block wall. The indented embedment line on the anchor helps ensure accurate embedment depth during installation.

What type of corrosion protection does the META20Z offer?

The META20Z features ZMAX galvanization, which offers extra corrosion resistance specifically suited for exterior and treated-wood applications, making it appropriate for demanding environmental conditions.

Can the META20Z be used on multi-ply trusses?

Yes. The META20Z can be used in pairs on both single- and multi-ply trusses. Its staggered nail patterns are designed to strengthen uplift resistance, and it can be installed straight or field-bent around truss or rafter members for added versatility.

What fasteners are recommended for installing the META20Z?

The META20Z should be installed with either 0.148 in. x 1-1/2 in. nails or 0.162 x 3-1/2 in. nails. It is also compatible with the Simpson Strong-Tie TSS truss seat snap-in and TBP8 moisture barrier plate.
